The idea of human beings living underwater might be a great solution in the future as the population is increasing in an alarming rate. We know that Earth is mainly covered by water , so it could actually serve as a major real estate in future. Underwater colonization is not that easy as we imagine. There are many challenges like lack of oxygen, high pressure,etc., which cause harmful effects on humans. But all these challenges are manageable as we are capable of finding solutions . It is our duty to provide and promise a better future for the next generation. Breathing underwater is major problem which needs a serious discussion because the pressure underwater might be immense. Artificial light will be the only source of light underwater. There will be a direct access to seafood and other foods and water can be transported using tunnels. Valuable minerals are present underwater which might improve the whole word's economy to a great extent. Electricity can also be produced from the massive waves using turbines. Underwater colonies can also serve as hiding places for humans to survive a great disaster. Measures are already being taken by scientists, architects etc, to promote underwater colonization. One of the best way to escape from growing threat of nuclear war, global warming etc., may come from moving people underwater.

Instead of being in the race of finding extraterrestrial bodies for establishing future home,we can actually try to develop our new colonies underwater.. Underwater colonisation has various kinds of positive and negative impacts.Positively speaking, underwater colonisation would instantaneously decrease population issues.Also,Underwater is somewhat familiar to our mainlands as those were once probably a landmass.We can avoid trying to build up an atmosphere to make a habitable zone in case of extraterrestrial colonies.We can actually gain access to sources of energy we have in underwater like wave energy through turbines.We can synthesize plants and crops to grow underwater so that food source is guaranteed. We can explore a variety of marine flora and fauna which we haven't seen yet.Underwater colonisation is very much useful in times of natural disasters happening in surface.Proper colonies made of glasses (submarine kind of habitats) would save us from underwater predators and ensure marine life cycle. Though underwater colonisation seems to be a good option,it has it's own various limitations and drawbacks.Proper equipments and accessories would become essential for survival in underwater. Underwater pressure is another major threat. When colonising on high depths, water pressure could be highly unimaginable. Proper sunlight would have been impossible when we had colonized oceans. So artificial sources would be required to produce photosynthesis and stuff.Living underwater could change our entire system. Our lifestyle and food culture would change as we would become extremely dependent on sea foods. So by Lamarck theory,we would become more likely to adapt the atmosphere and become an underwater species after many generations of survival. Finally,we could find a temporary economical colonisation rather by spending billions in space exploration.

Fiction has tried to portray an idea of underwater habitation for many years. The most recent adaptation of this idea that was widely seen by the mass was the underwater city in DC universe's cinematic adaptation of Aquaman.
With the advancing technology of today's world, coupled with the uncontrolled growth of global warming, it seems very likely that we may have to share habitat with our soon to be underwater neighbors.
The biggest concerns however related to underwater colonization would be the lack of presence of oxygen and the high pressure the water exerts in ocean depths. Life in the ocean may as well be synonymous with life with an oxygen cylinder and rubber diving attire. However, the idea of underwater colonization isn't new. Researchers and scientific minds have been working on an efficient solution.
Apart from the difficulties, the change in scenery will be one of the most biggest impacts on mankind. Man has been used to the blue skies and green fields. Underwater colonization would completely erode thar idea and replace it with blue seas all-around. Our lifestyle would also be affected as we will be more dependent on seafood rather than plants and mammals since vegetation, farming and cattle breeding seem unlikely underwater. People will have to be trained to survive underwater and be equipped with skills to face the difficulties that come with underwater life.
Since the blue planet is mostly water, the problem of holding a massive population would be solved if we are able to achieve a proper underwater colonization. Our means of transportation would drastically change with the idea of wheels being abandoned and replaced with submarine like vehicles. The sports industry will take a massive hit since most sports cannot be played underwater unless we build am artificial ecosystem ideal for human survival, mimicking the habitat on land, on the ocean floor with a large glass dome with oxygen. This dome, apart from acting as our new home, would provide us protection against hostile aquatic animals. If we are able to establish some form of artificial ecosystem underwater, life would not be very different. However the effort and energy required to pull something like that off is immense and does not seem feasible in the near future.
In an ethical sense, rather than trying to figure out how to colonize the ocean, it'll be wise to solve the crisis that causes the erosion of ice caps and let us live life comfortably, as we like it, above the surface.

Underwater habitats are underwater structures in which people can live for extended periods and carry out most of the basic human functions.Almost three-quarters of the surface of the Earth is covered by water. Humans are engaged in a number of activities conducted underwater like scuba diving, research etc. But however, almost a majority of the underwater still remains unexplored and is expected to have several million undiscovered species of flora and fauna.
Underwater colonisation is not an easy thing because there is too much pressure at that level which makes breathing extremely difficult. The density of water also causes many difficulties at that level. As the underwater depth increases, the visible light starts diminishing.
It has to meet the human physiology and provide suitable environmental conditions.Pressure, temperature,light, humidity these all differs.we will be more dependent on sea foods rather than plants(vegetables).The life will be totally different and it takes time for humans to adjust.
The underwater life also provides man with a variety of minerals and other resources for consumption. However,underwater habits and their technology designed to meet human requirements is shared with diving bells,submersible vehicles and submarines,and space crafts.Underwater colonies serves as hiding place for humans to survive from disasters,global warming etc...
Underwater colonisation is the best solution as our population will increase in high rate in future.
The concept of underwater world is very futuristic and one of the fascinating solutions similar to the colonization of Mars . An underwater settlement on Earth would be awesome, it would be cheaper to build than on Mars foremost because of its proximity. The collection of water and oxygen in the ocean would be easier. Food, too, for dishes like fish and seaweed.
ReplyDeleteBut there is a risk of having various health issues. Beneath the water surface, we will have very low access to sunlight, which we cannot produce artificially. So there is a great threat of being affected by skin diseases.
First, we need food. This will be challenging, depending on the depth of the colony. We can send cargo submarines or drones to deliver food supplies, but if we wanted to make the colony self sufficient, we would have to have immense structural expansions for farms. Trying to build such a large structure with today's technology is nearing the realm of improbability. Now, if we wanted our team of brave colonists to survive on sea food, we can make underwater farms that grow seaweed or other potential foods. Still, it will be tough to produce enough of this food for a full colony.
The major factors that restricts the possibilities of underwater colonies are pressure of the environment and we can't get access to all the facilities that we enjoy on land. Humans are terrestrial beings, they cannot get adapted to such circumstances.
Instead we could colonize the Mars, which almost have the atmosphere similar to Earth.

Imagine how funny it would be to share our life with aquatic organisms!!
Our life underwater would be "quirky". We have to make many changes in our lifestyle for sure. We have to totally replace the word " walk" by "swim".Yes ,we couldn't walk ! Our primary mode of transportation or movement would be " swimming". Of course we can use submarines for long distant transport.
Our skin would become like frog skin. The most awkward change would be that we can't change or wash our clothes. We would have to wear the same clothes. Even if we wash the clothes we can't dry it because we will always be in water right . Also no sunlight under water.
We have to always carry oxygen cylinder on our back like school bag and have to learn to live in darkness without sunlight.
Our eating habits also would have to be changed. We could eat only sea foods that too without cooking. We can't use telecommunication underwater easily . We have to find some alterenvironmentmeet our communication needs. Obviously no electricity. We should conduct many research and advancement to improve our life standard underwater.
In reality ,sudden transformation of our life from land to water environment definitely creates many problem in health and totally disturb our metabolism and routine before we could adapt it or making advancements. So. Unfortunately Unfortunately, life under water can never sustain ...

Global warming is the major problem that the world is facing today. Though the causes are not many , they are so worse that death is fast approching. The effects of global warming are innumerable. One of which is the melting of ice caps. If global warming was in a controlled level then the melting would also be in a controlled level and if that was the case then water scarcity will not be a problem now. But the rate of global warming is increasing drastically that the melting is causing floods over the world and the land area is fast submerging. If this continues then the living beings should shift their habitat from land to water and start living in the underwaters. But this is also not an easy task. The level of oxygen in the underwaters is very less that we have to create a oxygen layer for a effective living there. And we should learn to conserve all the natural resourses since we lack in all sources . Though the water level is rising ,the water for usage is very less. So we should convert melted ice into usable form. And storage of water is not a easy task. We should make suitable containers for the storage. Technology should pave way and many equipments have to be created for maximum utilization of oxygen and food. "A home underwater". Special type of buildings to withstand underwater. Health habits have to be altered completely. It would be like living in a different planet with different environmental conditions. Though we think of living in the underwaters it is practially not possible . But we would eventually adopt for all those consequences. Today we have technology and with help of these we can achieve to great extent and challenge any conditios. Are people willing to spend for environmental causes. According to us the environment is meant only for getting exploited. So if we even wish to live over there we people would again start exploiting the underwater that even that habitat will get destroyed. Though we people speak about saving the environment what we actually do is exploiting it. So living in the underwater is also not possible for the world in which we live. The only solution would be , we not explointing the environment and just leave it to itself to get recovered. In that case we can also live happily and the world will also be the same.

Underwater world is good option for the future dramatic world. Day by day the world around us is undergoing some drastic changes. Human intelligence crossed all boundaries and reached the extent of changing the law of nature. Living underwater is a cool idea,even thinking about it will be fun,but will it be possible for us to adapt to it. Sudden change of livelihood is very difficult. It needs some time to go along with it. We need to adapt to aquatic foods. Construction of Transportation facilities are difficult. Living things will need sufficient exposure to sunlight, or it leads to several health issues.WHAT ABOUT INTERNET,we cannot swim from Atlantic to pacific in search of signal. Our mobile technology not crossed the extent of underwater travelling signals.It is not easy to communicate with one another.Living underwater does not mean we are safe from natural calamities..There are underwater volcanoes that erupt and sometimes the result is the formation of an island. Thermal vents underwater erupt due to some disturbances in earth's core.Above on land we can run to safe and secure places at time of calamities,but what is the case if we are below the sea,where you will run.
So the point I am trying to make it up is living in underwater colonies is a sophisticated idea, but we must agree that the we are not limited by intelligence or knowledge we are shorted i.e limited by technology, budget, resources.So first we must fix the problems and find alternatives for our queries, before enacting this plan in future.
But really this is a really an awesome idea...everytime we dream about it while watching cartoons.But it just needed some time to do it.

Starting on with one of the major difficulties that we would face if underwater habitat for humans is possible; I would like to make one thing clear. The partition underwater is extremely difficult. We people engage in a lot of collisions for OUR LAND. Then the condition underwater? How could we specify that a particular part belongs to a certain country? We might end-up fighting for our portion of area. with the help of our technologies survival underwater might be reality soon. But before any construction starts, we must figure out how deep we can go. research by eminent scholars has indicated that humans should not build a colony any deeper than 1,000 ft or 300 meters. Anything deeper would cause serious risk to the structure and the people living in the habitat. the pressure experienced under water at any point depends mainly on the height of the particular layer from the open surface. as we go deep pressure increases. Because of the immense pressure, the walls of the buildings in the underwater city should be extremely thick, protecting us from exposure to excessive periods of decompression. At these depths, we need to take extra measures to ensure that there is a healthy ratio of oxygen to other gases in the air as the body requires varying levels of different air components when at pressure. The good news is that living on the ocean floor provides humans with large access to seafood found on the ocean floor. Even more so, more traditional meals and even fresh water could be transported through tunnel systems connected to the surface. Living underwater could help give scientists a better understanding of the planet and its early days. Not to mention there is a lot of resources still to be discovered on the ocean floor. Experts predict there could be an unquantifiable amount of minerals and metals that could be used to improve humanity and even help with the further construction of underwater cities. one major issue which stands as a huge rock in front of us is the population. number of people who could be accommodated under water would be definitely less than what’s possible on land. India itself is highly populated. then imagine accommodating the entire humanity. if the land is submerging, animals and plants too would be endangered. This indirectly affects us as we're the primary consumers. this in turn means a huge population depending on very less food. We humans are accustomed to specific cuisines. sometimes exploring new cuisines may sound cool. but definitely not in the long term. not everybody can adjust to the seafood. the dependence of the people on the sea animals would increase. this may lead to the extinction of underwater animals. at least on land, we separately have forests, zoo and so on. but that confinement is absent underwater. we can’t block them from roaming about in the seas. there are even chances of us being a prey to them. the mode of transportation becomes entirely different. no planes, trains, cycles, autos, metros, cars, bikes and so on. it would be mostly submarines. then imagine the no. of people who would become unemployed. for proper transporting the no. of submarines that we need must compensate the absence of the above mentioned. Vision might be a problem. So, there are chances for these submarines to even clash. Underwater habitation can be considered, but only as plan B.

Under water colonies is a phrase generally we come across in sci- fic movies and imaginary stories but if we are going to experience it in our real life then it will be like a unsolved puzzle with full of excitement and fun.
But thinking practically If we were going to lead a life in underwater colonies then it will be a life of both extremes that is pros and cons .There will be no issues which affects the ecosystem like pollution , global warming etc..which made a unpleasant life for us on the lands and also there will be no harmful effects due to ultraviolet rays. There will be a need for new modes of transportation.
Though , we have may have a pleasant life in underwater colonies there are many issues that we have to face in the underwater colonies. Initially it's quite difficult for humans and for other creatures in the world to adapt to a different livelihood rather than what we used to and also it is difficult to balance our body temperature since increase in depth of the seas will increase body pressure too it may lead to many consequences. We have to find alternate resource for food it may lead to vitamin D deficiency . Similarly we have to find new techniques to breathe inside the water , oxygen which is like a fuel for human cells isn't sufficient enough for us to breathe. And the construction of houses or colonies in underwater may require advanced technology and also it cost more.
Last but not the least there may be many cons for this idea but this does not mean that it's not a ban for human kind because we are just limited by our technology to satisfy the needs but there is a possibility that in future it may be a boon for our next generation when the technology satisfies all their needs to lead a life in underwater.

Living underwater is possible. You could be moving to an underwater city in the near future.The idea of humans living underwater may is not as crazy as you think. It makes sense to go out and colonize Mars, but the ocean is just as livable and is far closer to home. As you probably already know, the earth is 71 percent water. This could be prime real estate for future generations.
Living underwater does pose its host of challenges, like freezing, immense pressure, and a lack of oxygen. Not to mention, underwater living can wreak havoc on your body.
However, there are promising new horizons in the world of underwater living that could tackle these issues and have you or your future children living comfortably in the coming years.The good news is that living on the ocean floor provides humans with large access to seafood found on the ocean floor.There are Aquanauts who are currently living under water now, who are able to support themselves via spearfishing and pair that with canned and preserved foods.
How humans breathe underwater, and the depth of the structure are correlated, dictating how the structure should be created and the quality of air, humans will breathe in their underwater city.
First and foremost, humans should not build a colony and deeper than 1,000 ft or 300 meters.Anything deeper would cause serious risk to the structure and the people living in the habitat.
Because of the immense pressure, the walls of the buildings in the underwater city should be extremely thick, protecting humans from exposure to excessive periods of decompression.
At these depths, humans need to take extra measures to ensure that there is a healthy ratio of oxygen to other gases in the air as the body requires varying levels of different air components when at pressure. Plants and artificial light could help combat this problem.
Even more so, more traditional meals and even fresh water could be transported through tunnel systems connected to the surface.
The idea of living underwater excites scientists around the world including marine biologist and archeologists.
Scientists and researchers have better maps of Mars than they do of Earth’s own ocean floors. To this date, humans have only explored 3% of the ocean.

Living underwater could help give scientists a better understanding of the planet and its early days. Not to mention there is a host of resources still to be discovered on the ocean floor.
Experts predict there could be an unquantifiable amount of minerals and metals that could be used to improve humanity and even help with the further construction of underwater cities.

ReplyDeleteThe concept of under water habitation truly requires technological development and acceptance. As we could see now due to increased global warming world's ice is melting and sea level is increasing. If we fail to take steps in reducing global warming ,for sure we will reach a condition where habitation is possible only at underwater colonies. Definitely life would be so different under such circumstances. In the underwater colonies the process of breathing is quite difficult. We will have to think new strategies to adapt ourself to the new habitation. Since human beings are adaptive in nature we will get used to the new environment . Due to the new adaptation our body will change its temperature,pressure and so on according to the underwater circumstances. People will have to create new ways to transport materials from one place to another. People will have to eat sea food everytime since it's easily available . Reaserchers will play a vital role in finding new components under sea water and the government would invest huge amounts on such kind of projects. Since sea foods are the only eatables in underwater colonies fishing will become a major occupation for many people. People will become a master in swimming since they will not be able to walk anymore. However lack of sunlight will lead to more changes on our skin and body.
All these changes are more challenging than we think. But if such situations occurs ,then definitely human beings will find the optimal way to live under those constraints.

The fact that ice is melting rapidly would mean that previously uninhabitable areas near both poles would soon become habitable.
Setting that aside - as much as food, fresh water and air are staggering challenges, I will analyse a different angle from the others - the micro-organisms of the sea will be a devastating threat to our survival.
The Native Americans were defeated by their first encounter with European diseases before they ever met their rifles. (https://www.encyclopedia.com/science/encyclopedias-almanacs-transcripts-and-maps/impact-european-diseases-native-americans)
It is also very likely that there are some very dangerous microbes waiting for release from their icy prisons.
An undoubtedly traumatic shift to the sea would probably be successful for a small proportion of the population. It might be surprising to know that humans are actually not very genetically diverse - a small sampling of the population would not help.
If we did survive a pandemic, it would lead us to a condition called a 'genetic bottleneck'. In simple words, the population would eventually become more inbred than it already is, and that is a huge problem since it leads to more hereditary diseases and a smaller variety of infectious diseases to which we are resistant.
Take the example of the cheetah. Due to a near-extinction event in their past, they are all so closely related that you can perform a skin transplant between any two of them. A disease which is lethal to one is lethal to all of them.
To conclude, even if we survived the transition, we could be negatively impacted by it forever.
Underwater colonization is arguably a greater challenge than conquering space (which is why we have not yet bothered!) for another good reason.
We function optimally at a certain atmospheric pressure around us. Despite how rigorously astronauts work out in their spaceships, they are significantly weakened by the end. (https://en.wikipedia.org/wiki/Effect_of_spaceflight_on_the_human_body)
What would the long-term effect of the far higher water pressure be?
Electricity would be another major challenge, both in production (power plants use steam-powered turbines to generate electricity) and safety, for obvious reasons. Yet, the very advanced technology necessary to make living underwater viable requires an enormous amount of electricity.
Perhaps we could automate power plants on land (and more nuclear plants, as they don't require refueling that frequently) and find a way to transport that electricity underwater, protected by multiple layers of insulation.
A far more practical solution would be to colonize the previously uninhabited areas around the poles, or live on the sea in floating structures instead.

Let’s be honest, we are pushing our planet to a climate change catastrophe.Underwater colonies could be one of the best solution.
What if we lived Underwater cities?What would life be like?
Underwater living – our bodies aren’t adapted to it. If you dove 150 meters underwater without proper training or equipment, your lungs would shrivel to the size of a pop can and your veins would collapse. Descending all the way to the bottom of the ocean would feel as if you were being crushed under 14 full cement trucks and humans can't breathe in underwater. So We should build an underwater cities like "Atlantis" to stay.An individual human can't do it. So Bringing humanity undersea is something huge corporations might be interested in investing in to build underwater colonies.
Our underwater habitats would be rather small – populated with a few thousand good swimmers at most. We’d live in small modules made of steel, glass and cement designed for underwater use. Instead of going too deep into the ocean, we’d settle about 100 meters (328 feet) undersea.
We’d need to build life support systems that would maintain air composition, temperature and humidity. Keeping a livable amount of oxygen in the air would be our major concerns
With land-based solar panels that would transmit energy to the habitat. We could also use wave power – the undersea equivalent of wind turbines.
Our drinking water would be supplied through distillation or condensation. And all our waste would be most likely flushed out into the ocean.
Vegetarians might have to eat a lot of sea weed and plants which grow underwater. Finally something in the sea food section for non-meat eaters.For Non-Veg eaters there will be fish meat for whole life.
Earthquake will be one of the worst threat for erwater colonies.It can break the glass which protect us from the seawater. Your bedroom window gets a massive crack and water rampages through your living space. Or your life support system fails, leaving you to suffocate undersea.
The cool thing about all this is that we already have the technology to make it work. Although, so far, the longest an individual has managed to live underwater is 31 days, there are companies out there planning on building an underwater city like this.

The idea of humans living underwater may is not as crazy as you think!! An idea reserved for video games or sci-fi films, underwater colonies are a viable solution for humanity in the distant future.
It makes sense to go out and colonize Mars, but the ocean is just as livable and is far closer to home. As you know, the earth is 71% water and if all the world's ice is fast melting and land is fast disappearing our world will be filled with water.
Living underwater does pose its host of challenges, like freezing, immense pressure, and a lack of oxygen. Not to mention, underwater living can wreak havoc on your body. We need to build colonies which could overcome these.
Scientist have planned for underwater colonies for a long time. In 1963 seven divers lived underwater off Sha’ab Rumi (Sudan) in the Red Sea for one month under the supervision of Jacques-Yves Cousteau. The colony consisted of four manned habitats including a hangar for the DS-2 Diving Saucer and a tool shed. Eight additional structures including shark cages completed the colony. The main habitat called Starfish House was located at 10 m (33 ft) while the smallerDeep Cabin was located at 26 m (85 ft). Interesting right !! These had few drawbacks... These could be rectified and we can create a great underwater colonie for humans to accommodate .

It can be possible but not for long period of time...
More than 80% of our population will be affected because we need huge amount of required accommodations to live in underwater such as oxygen , food ,and other necessities to live ...
We can go for other ways to live in underwater but air is main problem.... Since there is no findings by scientist about air without trees and converting oxygen from water.
There will be few changes on us to adopt living in under water like No telecommunications,
No sunlight in depth of water,
Health issues and
Foods without cooking.
If we live in under water colonies , there must be less pollutions. There is always *eco-friendly* to environment. There is no non biodegradable wastages such as plastics that causes water to pollute.
For our food we can go for *KELP* (algae) but it is high rich protein, iron, calcium etc., which is available in plenty. We can cultivate plants by *HYDROPONICS SYSTEM* method by desalination method (freshwater). And mostly based on aquatic animals.
But for oxygen we need certain alternative ways to live. We have lungs and not gills to extract oxygen from water.
We took alternative ways for clothing’s and shelter. But many aquatic animals were disturbed by us. More kinds of birds and mammals will be extinct.
For power we can generate by turbines, wind, and solar energy.
However it is not possible to live in underwater which occurs within 50years. There is always a need for everything to live there.

Looking at the current rate of global warming, humans have to come up with contingency plans to face global warming apart from trying to prevent it. Though the idea of underwater colonisation seems to be a bizzare plan. It might turn out to be one of the feasible ones.
We have already seen underwater colonisation depicted fictionally. The most prevalent example would be DC universe's Atlantis. In this world, the people living there have the ability to breathe underwater and on land. Pragmatically, will it be possible to attain the same? It seems very far fetched. But, maybe after a century or two, advancement in science and technology could help us achieve it. Modifying the genes of our race to help us breathe underwater might be possible to achieve, provided that we have the time to reach such a level of advancement in science.
If we are in dearth of time, the above solution is absurd and practically impossible. We would have to create an underwater environment for us to breathe air just like we do on land. Something of this sort has already been implemented in a small scale around a decade ago. A hotel in Fiji named 'Poseidon' is an underwater resort. There are approximately seventy pressure habitats that are suitable for humans to live in. There would be no physiological effects of hydrostatic pressure. Implementation of a structure of similar type on a large scale would be a challenge of immense difficulty. But it is achievable, provided that an abundance of resources are put into creating such an environment.

ReplyDeleteWe have seen the portrayal of underwater colonies in sci-fi movies and in novels but, in real life , the concept is still on research. Due to over-population and depletion on resources on land, we look out for this option, but at least for the present generation, it does't seem like a viable option.
Cons:-
1) Breathing is a main issue. Oxygen has to be provided from the surface and also the access to fresh water and power supply isn't easy and is very expensive.
2)Moreover, a colony cannot be built deeper than 100 feet because anything deeper would cause serious risk to the structure and people living out there.
3)Due to immense pressure underwater, the walls of the buildings have to be thick, in order to protect humans from danger and excessive periods of decompression.
4) Also, there should be a healthy ratio of oxygen to other gases suiting to our body requirements at sea level pressure. For this, plants and artificial light could ease this problem but are not a perfect viable solution.
5)Transportation will be a huge issue. Only top submarines can travel at a speed over 30 mph.
Pros:-
1)A large number of companies are working on the projects related to underwater colonization and many of them claim to be successful in forthcoming years. For instance, A Tokyo based company is working on project named "Ocean Spiral City". With its massive turbines, the city would power itself through the power of waves, tide and ocean currents, thus, solving a major con and is said to become a reality by 2030.
2)Food won't be an issue due to the availability of plenty of sea food and sea weeds can be cultivated out there.
3)Apart from that, quantifiable amount of minerals and metals are available for the sustenance of human race.
Although living underwater is expensive and not a feasible solution for the current generation, with the technological advancements in near future , it can become a reality within a few decades. With the depletion of resources, and increasing population, we might arise on a solution of colonizing underwater instead of inhabiting on other plants if it turns out cheaper in former case. Moreover, once the colonies are set , maintenance would be lower than that on surface.

Well we have been exploiting our resources and the earth for years and years being ignorant about the consequences that we would have to face. And now we are thinking about the solutions for the problems we have created.
We have increased global warming with our selfish practices and have occupied the entire land on earth. Now since we are running out of space on land we are thinking of moving into underwater colonies. Well this might sound exciting for few, but there would be many challenges that we would have to face.
Breathing under water will be the major issue. Oxygen would have to supplied from the surface or a dome shaped structure must be built that is filled with oxygen. Food might not be a problem as there is large access to seafood and can also be transported using tunnels. Drinking water can be acquired by treating sea water.
Another challenge is to deal with high pressure under water. But it could be tackled with the advance technology that we have. Human activities on land should be done in the dome shaped structure.
Well with the technology that we have it is feasible to live under for a small population. But it has yet not come to reality due to lack of interest, motivation and funding.

Ice masses melting all over the world at a fast rate, decreases the land areas. As,humans conquer and compete everywhere ,they will be occupying the underwater a soon . So,is this a solution to decreasing land areas?No. Colonies below water will totally affect the water society of amphibians and other creatures. And also we can't adapt to that surroundings with high pressure and low oxygen level with salt water damaging our homes.
Moreover, we can't produce nutrition over there. It is imagine to live in water world,but it is not possible.The reason for under water colonies are "we the humans". We can think of a way to stop this crisis than to escape that. So, never think of these colonies. You can live not every butterfly and deer beneath tonnes of pressure.

What if underwater colonization happens,
For the last century, outer space has been considered "the final frontier". But when over 70% of Earth's surface is covered by water, perhaps there's a whole other frontier entirely.The deep seas are waiting for Hyman's habitation.All eyes are currently on space and there is a more buzz around the idea of transforming Mars into a better place to live and building stations in moon. But the oceans are much more accessible, we don't want to leave our planet. In both the cases we should have to construct sealed oxygenated living space from the outside environment. One difference is that in space, extreme temperature pose a major challenge, while in ocean the problem is extreme water pressure. It is certainly an issue though, and it probably wouldn't be a great idea. But we have already sent manned submersible to depths of over 35000ft.An advanced under water Colony would only cost a fraction of what it would cost to colonize in space. In fact Design are already in works. It might also pay itself faster through undersea tourism, mining opportunities and it makes the transportation Easier. The main obstacle is to provide oxygen but we can over come that with the technology what we have.Electricity can be generated from tides.And other resources can be fetched from the terrestrial bodies. It could help us from environmental land disasters. For example we can escape from floods. But in some areas, ocean colonies
would be at risk under under sea volcanic eruption, earthquake and tsunami. Even ocean currents can affect ocean colonies. So the location should be chosen wisely considering all factors. At the same time we should not disturb the underwater ecosystem. Again it's a way to escape from global warming because the warmer regions are becoming unhabitable. The colonies will be isolated and there won't be a realistic environment. We human beings depend much on terrestrial bodies and we have been living here for many years so it would be demanding and difficult to live underwater. But for increased living space we can colonize ocean with what technology we have now.

Due to global warming, our mother Earth suffers seriously with the melting of glaciers and the disappearing of landmasses. So humans will have to move underwater in the later years.We have to develop new colonies underwater.But this is not an easy task.It has its positive and negative sides.
Positively speaking, we can get easy access to food like marine creatures like fish, seaweeds,etc.We can consume algae whic are rich in protein and calcium.We can easily escape from man- made disasters like war,etc. We can use plenty of natural resources found underneath the ocean floor like minerals,etc. Due to advancement in technology,we can generate hydro electric power during high tides.We can hide from enemies and predators.We can easliy get access to any materials through ocean tunnels.
Negatively speaking, pressure changes at high depths becomes difficult for survival.There is insufficient sunlight available for photosynthesis at greater depths.Therefore, an artificial light must be induced for photosynthesis.Some people are alergic to seafoods.This causes health issues.As fish has gills for breathing, they can easily extract oxygen from water whereas human beings (having lungs)experience oxygen deficiency at greater depths thus finding difficulty in breathing. This could be overcome by using an oxygen cylinder.We can escape from man made-disasters but not natural disasters like tsunami, etc.We have to swim for mobility rather than walking.Submarines may also be used for transportation.Desalination of seawater is not an easy task and it is very expensive.
Underwater colonisation is not a good decision now but it could be a good solution after many years with the advancement in technology.

As sea levels and populations rise, and we begin to run out of space on land, some pioneers think that we should begin to colonise the oceans.
That would have the best life anyone could have. Just like sci-fi, you can have everything you can imagine. The underworld life will be full of color and mystery, that would fascinate the mind of everyone. We don’t have to worry about living under is the hassle of traffic, commuting. Creatures of the underwater, big and small will be hunted by humans can be used as ornaments, decorations, food.
Although underwater buildings exist since 1960 but no one have heard about it. Everything can be built underwater like houses, hotels, restaurants to let people have a good life or vacation. The glamour view underwater of fishes, coral reefs and different creatures encourages people to build and live there.
As there also many cons like density of water also causes many difficulties at that level. As the underwater depth increases, the visible light starts diminishing , and an underwater habitat has to meet the needs of human physiology and provide suitable environmental conditions, and the one which is most critical is breathing air of suitable quality.

As the ice at polar caps are melting at rapid rates,we have to tackle the problem of rising sea levels.One possible solution is to move to underwater cities,similar what we have read about the city of Atlantis or what we have seen in the movie Aquaman.
Though the human race has adapted itself to the changing environment over millions of years,it will be difficult to adapt ourselves to live under water.One major problem is the lack of oxygen without which it's going to be a hard to live.There will also be a necessity to change food habits as cultivation of crops under water will be difficult.As a result atleast for the initial times we will end up eating marine organisms in a large extent that we end up risking many of the species.Another problem is building of a proper protection globes for each cities which can protect people from the saline water and harmful creatures.And also maintaining it is going to be a tough task in the future.Transportation will not be that easy and people will be restricted to the places they live which can have effects on the economy which is very important for the maintenance of these cities.Sewage disposal is also going to be a problem as we humans tend to let it mix with the surrounding sea water which will cause water pollution which inturn may affects the quality of water which we drink if we are to stay in those cities.We humans have created a world filled with technology and hence we will find it difficult to start over again with no electric gadgets as power supply in these cities will be damn difficult.Building these cities cities in such a way that it can withstand seabed tremors and underwater phenomenon is far beyond our current technology.
Though we humans are capable enough to overcome all the above problems and develop proper underwater cities, it would be better if we can reverse the damages done atleast upto manageable levels.

“Underwater colonisation” - At the outset, this looks like a zesty state-of-the-art idea.But, as we cogitate on its design, we have to face a multitude of hitches although I personally have no qualms against it.
Apart from the conspicuous problems such as Oxygen , Pressure , etc, the major glitch in this plan according to me is communication.No life is meaningful unless we get to share our ideas and communicate our thoughts. This may not be that simple underwater as sound waves have to travel through water and hence they happen to be incapable of vibrating the ossicle bones in our inner ear which subsequently make us incapable of hearing things in a way that we would like to. So, we have to figure out alternatives to combat this problem.
Also, the concept of a boundary would perish and the entire world would become one single mass which is kind of weird as this would lead to chaos all over the park. Generation and transportation of electricity would be another major concern as water is a conductor of electricity and hence, we have to be very careful in handling electric current which if we fail to do would lead the entire human race to perish in a jiffy.
Although we do have significant pros like more space to accommodate people, good food , less pollution, etc, I would like to unfortunately tag this concept as a “MYTH” atleast in the near future as there are a billion different problems associated with transforming an all time land life to a completely oceanic living.But who knows, we humans are known for achieving the unachievable and we have proved that time and time again.So all I would say now is - “FINGERS CROSSED !!!!”

One of the best ways to combat the global warming and fast melting of ice may come from moving populations under water.
Here comes the challenges to be faced in underwater colonisation.Breathing is an obvious issue. Since humans do not have gills, we cannot extract oxygen from water.Oxygen will have to be supplied from the surface, and underwater citizens will also need access to fresh water, food and power.While drinking water would come from desalination technology, and could be transported through tunnel systems connected to the surface. The good news is that living on the ocean floor provides humans with large access to seafood found on the ocean floor and also with underwater farms.High pressure is one of the most difficulty in moving population underwater.Because of the immense pressure, the walls of the buildings in the underwater city should be extremely thick, protecting humans from exposure to excessive periods of decompression.
At these depths, humans need to take extra measures to ensure that there is a healthy ratio of oxygen to other gases in the air as the body requires varying levels of different air components when at pressure. Plants and artificial light could help combat this problem.
Finally our bodies aren’t adapted to underwater living if you dove underwater without proper training or equipment, your lungs would shrink and your veins would collapse. So this transformation may lead to life threat sometimes.

The technology already exists to create underwater colonies supporting up to 100 people.If you had the money and the need, you could do it today.But technological advances would be needed to emergency evacution systems,oxygen supply and humidity.To be self sustaining, future habitats could potentially grow plants using natural or artificial light to generate a fresh supply of oxygen, or develop other methods to produce their own oxygen.Explorer Ian Koblick and his colleagues lived under the water for almost 60 days,they did not experience any ill effects and he thinks that staying below the water can be feasible upto 6 months.Fresh sea food is available,so food will not be a concern.Depending on the size of the colony the human waste could be treated and released into the evironment or converted to fine ash.Electricity can be generated from the wave tides using turbines and placing solar panels on the surface.Oxygen will have to be supplied from the surface while drinkking water would come from desalination techonology,where food from underwater farms.Since the pressure under the water increases for every 10 metres deep,the colonization should not be more than 150m.
Conshelf, Marine lab, Hydro lab, Aquarlus, New World Explorer are some of the under water habitats.The oxygen supply system has a surface mounted air compressors in conjuction with Carbon di oxide scrubbing systems to absorb the carbon di oxide exhaled by the humans.Another alternative is gene mutation,as shown in the sci-fi movie waterworld where kevin costner has gills to breathe and webbed feet to swim.

This topic is revolves around the effects of global warming, which we humans did not take it serious. Although underwater colonies look like a solution, it also has some disadvantages.
Positively speaking, it would be a new life, change to mankind. Underwater colonies provide the means of safety from natural disaster like meteor shower, UV radiation, low pressure cyclones etc..
But imagine how a world would look like in underwater. There would be no sunlight. Moreover, being in an underwater colony, it is closer to the Earth's core which would make the atmosphere hotter and we will face lack of oxygen.
The area of land surface would decrease as the radius of Earth decreases when we move towards it's centre. Practically speaking, it is impossible to create an atmosphere down there, same as here. And also, it would be difficult for many people to adapt to it. Moreover, being in underwater blocks our vision from the sky i.e., one would feel like being imprisoned.
If we humans take global warming seriously and follow remedial actions promptly and consistently, then none of this would happen.

ReplyDeleteThere are vast areas on planet earth which have not yet been explored; primarily the oceans; when humans can control rovers on Mars and study about extraterrestrial bodies colonization, the idea of underwater colonies isn't far fetched.
On approaching this as a potential solution from an optimistic view, it would help us explore and study the ocean in depth. Food wouldn't pose a problem given that the ocean is a home to a variety of flora and fauna. Considering the rapidly increasing population and shrinking of land mass due to water level rise, underwater colonies seem to be a logical idea. Underwater colonies can provide us a safer and cleaner alternative to the current one, considering high levels of pollution and harmful rays. This can also be a solution to the cramped and congested urban cities, ocean area is three times more than the current land mass. Regulating weather to suit the desirable levels for normal livelihood can be done. Water crisis can be put to an end, if proper efficient desalination technology is invented in such a colony.
The main drawbacks would be to build a structure that would stand immense pressure constantly. The colony would require pumping in of oxygen with other vital air components on regular basis in appropriate specific amounts. The colonies should be built to withstand during natural calamities as even a small mishap would lead to a huge loss of life and money. Cultivating food crops and other essential crops in the ocean beds will require deep research and study as the mineral content would vary drastically.
The whole futuristic idea of underwater colonies can be a realistic vision for a post apocalyptic earth.

It wouldn't take much for one to figure out that we are exploiting the resources around us at an alarming rate and our survival on earths landmass seems almost impossible in the near future.It wouldn't be wrong on our part to search for alternative habitats for our survival.Most scientists believe that our survival lies in colonising other planets primarily Mars.
But I would like to direct your attention to something which I believe we have all seen in our childhood, The fictional underwater city of Bikini Bottom.Haven't we all dreamed of having burgers underwater from Krusty Krab.I strongly believe that with the rate at which technology is developing an underwater city is not that far away in the future.
One of the biggest concerns raised on underwater cities is about the insufficient amount of Oxygen dissolved in the water and that even the little Oxygen which is dissolved is almost impossible for us to inhale cause of the absence of a well adapted respiratory system.One suggestion put forward is to carry oxygen cylinders with us, But that is a cumbersome process.Instead we can develop mechanical inhalers which can act as artificial gills for us.This will eliminate the need for us to carry heavy oxygen cylinders everywhere with us.
With over 70% of the earths surface being covered with water we will never have to face the problem of overpopulation again.
Almost every aspect of our lives would change, On land Fire was man's greatest invention after wheels.Both of them would be obsolete in underwater cities.For transportation people would not be using vehicles with wheels but instead be using vehicles with propellers.
Large amounts of pressure at the ocean bottoms is another hindrance in the path for underwater cities to become a reality.This I believe can be solved by covering the cities with a dome like structure to maintain habitable pressure.And for transport between cities the concept of hyperloop can be used as it uses pressurised tracks.
Thus I believe underwater cities do not seem impossible but there sure is a lot of work to be done on this.I believe one day all of us can actually live in a pineapple under the sea.

ReplyDeleteThe thing that came to everyone's mind is the mythical city of Atlantis which is protrayed as the city of wonder and even as the place where Aquaman lives. Underwater colonization is not a new idea which has to be discussed but when a time came and we have to move on to a colony like that is a pressurized situation , it is even more pressurized situation when it is faced by a problem of constructing an architecture which has to be withstanding the underwater pressure and then the oxygen will be the second problem as it was the sun rays don't enter there so we can't even grow plant underwater then the dissolved oxygen in underwater is very low than the surface as the water is not in contact with air . Even if we come up with an alternate solution for oxygen and pressure . The transportation between the areas of the colonies is a difficult one . We can build architecture underwater but they won't be cost efficient one actually , because a small fault architectural fault can make the architecture to fall , which we cannot risk pepole life upon.But if we can overcome these problems we get a larger benifits we can stay on earth even when there is the biggest problem faced as a terrain people , Global Warming is the major concern , we're taking necessary action which are not that much effective one which results in climate change , melting of ice bergs . We can start a peaceful life living in bluish environment eating planktons and fishes breathing unpolluted air .

We the selfish humans destroyed our own assets and going in search of some fantasy and crazy assets(underwater colonization, mars colonization, space colonization, underground colonization...)
Though it is a crazy idea, Money and need can make impossible possible in today's world.
Thinking about underwater colonization, we get the following ideas:
*Habitat safety:
With safety being paramount, operators assure underwater habitats are running smoothly by monitoring life support systems like
-> air composition.
->temperature
->humidity ....
(Because this may collapse the ecosystem)
*Food:
We can create large access to seafood. Cooking can be made in a separate chamber and processed.
*Transportation:
Transportation occurs in submarines, ships, and boats.
*Fresh Water:
We can transport fresh water from the surface, but water could be created using condensation or desalinization.
*Waste management:
Depending upon the size of the colony, human waste and dead bodies could be treated and released into the environment or cooked down to a fine ash.
*Pressure:
Underwater the pressure is much greater, causing gases in the bloodstream to dissolve. This can result in the feared condition known as the bends, which can cause intense pain and even death.
Below certain depths extra measures would be needed to ensure a healthy ratio of oxygen to other gases in the air – around 500ft (150m) for nitrogen and below around 1,000ft (300m) for helium. This is because the body requires different levels of different air components when at a pressure
Keeping the above ideas I suggest colonization above the sea surface.
#This is a structure that projects outside sea level and steel pillars can be used to carry these structures.
#This exempts pressure management, easy fishing, easy cooking, transport in boat and helicopters,...

The idea of underwater colonies is a bit interesting one that is already being used in sci-fi films and video games.It makes sense to go and colonize Mars but our ocean is just as livable and nearer to us.As Earth contains 71% water it is also an ideal solution to control population bomb. Looking at the increasing temperature,global warming and climatic changes living underwater may seem as a good one but there are certain challenges that the humans must face before they get to adapt themselves in their new environment.Immense pressure,lack of oxygen and sunlight and freezing temperature are the primary challenges that one must face. Speaking about building the colonies,humans should not build a colony deeper than 1000 feet or 300 metres as anything deeper would cause serious risk to the structure and the people living in the habitat.
Because of the immense pressure, the walls of the buildings in the underwater city should be extremely thick, protecting humans from exposure to excessive periods of decompression. At these depths humans must take measures to ensure healthy ratio of oxygen and other gas components at respective pressures. Artificial plants and light might help to tackle few problems. Food will be the thing that humans would least care about as there will be a large access to sea food.
Underwater colonization might improve the chance of survival of a species.But the communication and transportation seems to be a secondary challenge and technology must find an answer to the upcoming reality.As many wish to live underwater just to see how exciting it could be and sad state is that humans have only explored 3% of the oceans!

Global warming is one of the major problem that we are facing today. Because of this if ice melts, the land may be disappeared. Then we must move to underwater colonies.
If we start to live in underwater colonies, our lifestyle should be completely changed.we should try to adapt ourselves to the environment and it is really difficult and it may lead to the change of the environment of underwater and the species live in the underwater get affected.
Underwater colonies is not an new idea. It is possible to live in underwater colonies. But in the early stages, there will be no transportation and communication as we like .
We have to face many struggles in daily life till we get adapted. Ther will be no proper oxygen and food and it is the basic need of humans. It may lead to some new diseases. There won't be much job opportunities. It will be much more difficult for everyone to get adapted.
I think, if we start living in underwater colonies,using our technologies we can able to create a good atmosphere for our future generations. And one day the underwater colonies may also disappear just like the land disappeared. So taking actions to control global warming and life on land is the better solution.

Global warming is already having significant and costly effects on our communities and our health.So it is our prime duty to provide solution for future generation to lead a healthy and wealthy life. One such solution for that is underwater colonization.
Building human habitat on the ocean floor is possible, but very technologically challenging. Even in shallow (<100m) waters, it is much more convenient to have above the see level platform and perform all bottom activities from there. So nothing is impossible. Scientists have already explored their ideas regarding underwater colonization.
But Oxygen and extreme pressure would be major risk factors for survival.In deep sea,the temperarure difference of deep and shallower waters could be used to drive a power generator.While drinking water would come from desalination technology which would be a full stop to the problem of alarming water crisis.The underwater life also provides man with variety of minerals and other resources for consumption.
But there are also other factors which should be taken for consideration.For example,our food habits will completely be dependent on seafood rather than vegetation and farming as it is not possible in underwater.Proper sunlight would have been impossible when we colonize oceans.Transportation will also be completely different as there are only submarine vehicles.Construction of houses will also require advanced technology which will be highly expensive and it will not be possible for poor people.
So taking all these factors into account,it is important to create a artificial ecosystem which satisfy all the above mentioned needs with highly advanced and improved technology which will not be possible in the near future.So now we should protect all our natural resources to make our blue planet a better place to live.

Colonizing oceans is profitable, challenging, feasible, and doable. There are still a lot of questions to be answered. How will we construct an underwater city? What will people do there?
Ocean colonization is one of the solutions to the overpopulation. Oceans cover 70% of Earth. The surface area of all habitable land on Earth is 24,642,757 square miles. So, we can make our planet 50% larger! This will solve the problem of overpopulation for a few generations. And as inhabiting oceans makes colonizing other planets easier, this is a long-term solution as well.
90 000 people killed in natural disasters every year and underwater cities would act as a barrier for humans .
If you play video games, read science fiction, or watch futuristic blockbusters, you can remember a dozen submarine habitats.
The Floating City, the Ocean Spiral, the City of Rapture these are the three potential ocean colonies project . This future might be closer than you think: Shimizy corporation claims the first Ocean Spiral will be ready for residents to move in by 2030. In ten years, we’ll have an opportunity to look at an underwater city with our own eyes, not with our imagination.
I hope.

It's always been fascinating, the idea of underwater habitation. It hasn't become a reality yet, but what would life be like if humans had to move to underwater colonies?
The idea seems very futuristic, but with the alarming rates at which the human population is increasing, it seems as though we need to start thinking about colonization underwater much sooner.
The population on land can be controlled if humans start moving underwater, consequently reducing pollution and traffic on land. It will allow the surface above water to replenish and restore itself from the damage made. Colonization underwater could also mean more land for activities like agriculture, industries, farming power generation etc, because there is, in fact, more water than land on our planet.
But I feel that there are more complications and drawbacks to underwater colonization than advantages.
It will be very difficult to adapt to the new environment. Humans are not equipped with skills to face the hardships of underwater living and will have undergo education and training to survive the same. The most apparent hitch is the inability to breathe underwater due to the lack of oxygen. So people will have to travel around with heavy oxygen cylinders under the immense pressure of the depths of the seas, unless we find a way to mutate ourselves to breathe dissolved oxygen. This calls out our next hindrance to and easy life underwater, and that is travelling. Humans would have to learn how to swim. And even if there were vehicles available, it would eventually lead to traffic underwater. The requirement of housing or shelter for humans will lead to destruction of the existing life underwater and such underwater will require suitable architecture and build. Increase in vehicles, shelter, population, industries, etc will obviously lead to increase in pollution and will be an impediment to the already existing flora and fauna. It will disturb the natural underwater ecosystem. We might have to build regions that are similar to that on land, filled with oxygen, where one can walk and needn't swim. There are many such limitations and obstacles that accompany this unprecedented idea, and we could go on listing them.
It would take enormous amounts of money ,time, effort and skill to achieve something like this.
With the advancement of science and technology it is possible to see it become a reality, but nowhere in the near future.
Instead of trying to escape the destruction we've already caused on land, we should work towards rectifying it and look for viable solutions to make the earth a better place to live.
Living under water does pose it's
ReplyDeletehost of challenges like freezing, immense pressure and lack of oxygen, density of water. These can be overcome by modern technologies.
Earth is probably 71 percent water which could be a real estate for future generation. Humans have only explored 3% of the ocean. If we can imagine humans living on mars, then why not humans readapting back to our beginings and live underwater?
But with modern technology it's a wonder why great efforts haven't been put into finding a way which humans can exist and live beneath the sea's surface. It significantly help with the problem of over-population and safety from various natural or man- made disasters.
The problematic issues with creating underwater cities would be finding the place for emergency evacuation plans and regulating air
Supply and humidity. Basic needs like fresh water through condensation or desalinisation and plenty of nutrition underwater and fresh seafood ,electricity through turbines , artificial light inorder to generate fresh oxygen is possible . Won't it be a good option for us to colonise the ocean?
Life under water is one of the most exciting things in the world. The same is characterized by plants which exist in a wide variety, aquatic animals which are both dangerous and sober, microscopic organisms which are the basic food of the animals.
Even the largest mammal in the world ,the blue whale, resides in tht oceans. Thus, the life underwater is a part of the life on earth.😊😊

The glaciers in the poles are melting due to global warming. The land area occupied by human habituation is rapidly increasing due to increase in population. Due to the melting of glaciers, rise in sea level leads to the decrease in the land area. Underwater habitation is one of the solution to this problem. But underwater habitation has it own flaws and positives.
What will happen if underwater habitation becomes reality?
1)underwater cities will be protected using special equipments to withstand the high pressure under deep sea.
2) there will be a transport system for carrying food and water from the land area or synthetic foods might be used.
3) new transportation system will be developed to connect the land and underwater cities.
4) underwater ecosystem will be affected due to the human habitation.
5) many rare marine animals will lead to extinction.
6) everyone will be wearing oxygen mask for breathing as there is only dissolved oxygen in water.
7) first of all it will take time for us to psychologically adapt to the underwater habitation.
8) it will lead to many new inventions for adaptation in under water cities.
9) new culture will be formed.
10) artificial lights will be use during day times as the sunlight cannot penetrate into the deep sea.
11) crops cannot cultivated as there will be no sunlight.
There are many other points which also can be added.There are many flaws in underwater colonization so, Instead of planning for underwater colonization we can take necessary steps to stop melting of ice burgs and glaciers.

Climate change is true and is happening right under our noses. In order to mitigate this hazard, we prospect to colonize the up and beyond, rather avail the abundant aqua around us.
The basic necessities of man for survival : food, water, shelter, clothing,electricity, transportation and connectivity ( The latter three being a neo-sapien addition), with the perfect funding and research, could be attained.
With structures made of high strength steel and unyielding reinforced glasses, the immense pressure of the ocean water and the harmful radiation can be withstood. In case of ozone depletion too, the water above us would protect from the radiation.
With the the major potable water resource (glaciers) united with ocean, we rely on desalination plants and reverse osmosis engineering.
Pod agriculture, hydroponics, artificial light agri and our existing schools of fish can satisfy the hunger.
Ocean Thermal Energy Conversion plants, Tidal energy and underwater mining for crude oils will power our subaquaceous cities.

The newspapers are being blanketed by stories of drought, depletion and death, primarily caused by Global Warming, a wake up call ringing through the forests on fire, the dry reservoirs and eventually falling on the deaf ears of the people that dot the Earth. Studies show that due to the rapid descent of the Earth’s health, humans may have to resort to underwater colonization. Underwater colonization is the theory or practice of permanent human settlement beneath the surface of our water bodies. To begin positively, the ideology of colonizing underwater proves to have certain benefits, such as expansion of living area, exposure to underwater resources at a deeper level, new recreational activities and ultimately entering a safer living space. However, we have to be able to tackle the obvious problems like immense amounts of pressure, lack of oxygen and sunlight. Transportation is going to be a huge problem underwater. But I think an underwater tunnel transportation(for example: Hyperloop) is a plausible public transportation solution. Instead of cars and bikes, families living underwater could possess mini-submarines. The next obvious problem would be food. To tackle this problem, we must have ready-made food products which could be hard to invent but I think Earth's greatest minds could pull it off. Truth be told, living in an underwater environment would be pretty much termed as "survival" as we wouldn't be able to accomplish the other recreational activities which have been made possible on Earth and by recreational activities I refer to sports, cinemas, businesses, etc. However , in reality, this solution may be just a ripple in finding a solution to the problem. With regards to India, the reservoirs are empty and the few bodies of water that are remaining are slick with garbage and toxic substances. The theory of underwater colonization is the very essence of a theory considering it has not been tested by the masses. The only other option being space colonization which is far fetched and in turn might give leeway to shelter beneath the shore but despite it being a step in the right direction, I do not believe that it is an apt solution. For now, we must do what we can to save all the elements in all ways possible. Reusing, reducing, recycling, eradicating plastic items, decreasing pollution in all forms, taking care of the Earth in all the little ways we know, this is what is important. The simple truth is that we are a part of our Earth and whatever we do to it, we do to ourselves as well. Global Warming is no longer a prediction. It is a reality.

Due to increasing global warming and other problems such as overpopulation, underwater habitation can be seen as a better alternative to living on land. The beautiful marine life and multicoloured aquatic plants will be our new environment.
There would be no global warming as we would use under water volcanoes as energy for thermal plants which convert that energy into electricity. Our modes of transport also would've changed and we might be using hyperloop technology to get us to places faster than an airplane at the cost of a train ticket. Our technological advancements are paving the way for making this dream into a reality.
The main problems we would face are:a lack of breathable air and the immense pressure threatening to crush our organs. Artificial air can be created using special masks or even genetic engineering can allow us to form gills and the capacity to withstand pressure by having a different type of biological setup

ReplyDelete71 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all Earth's water.
Scientists have claimed that only 3 percent of the oceans have been explored.Now this opens up a huge opportunity for underwater cities.
This idea looks fascinating and seems to be an appropriate solution for overpopulation and global warming .Though the research for underwater habitation started way back in 1967 we are still many decades behind establishing it.
Transition from land to underwater would be the biggest concern here.The amount of area that needs to be constructed is humongous.Also,this should be done without damaging the ecosystem of the oceans.
Constructing a city underwater would lead to depletion of millions of species.First and foremost, humans should not build a colony and deeper than 1,000 ft or 300 meters.
As we move deeper down the ocean the pressure drastically increases.At these pressures the structures of the underwater cities are prone to damage.At these depths, humans need to take extra measures to ensure that there is a healthy ratio of oxygen to other gases in the air as the body requires varying levels of different air components when at pressure
The Ocean Spiral is a concept suggested by the Japanese Shimizu corporation.The spiral will stretch from the seafloor to the surface.Architects at the Shimizu Corporation have already placed a $26 billion bet on the future of underwater cities.
But even this 26 billion dollar prototype can support only 5000 people !.So the cost for accommodating an entire city would go way beyond calculations.
By constructing these cities many deep sea resources could be mined.
Commuting underwater can be done using submarines and specific tubes.Hyperloop technology could be also used underwater by making the takes water resistant.
Though the idea of underwater colonies looks cool,the amount of effort,manpower,money,research,etc..... required for establishing these could be put into solving our excisitng crisis such as global warming,overpopulation.
World population is growing rapidly , According to the Census (USCB) estimated current population of the world is 7.012 billion. Statistics show that global population is expected to reach between 7.5 and 10.5 billion by 2050. As the total land area of the earth is fixed, population density of the earth is also gradually increasing it makes life impossible for human being to live on the earth. So, for accommodating this increasing population man has started to find several alternatives, which include finding for another planet where people can live.But what if we turned our eyes a little closer to home?
ReplyDeleteThere are vast areas on planet earth which have not yet been colonised; primarily the oceans, which cover 71% of the Earth’s surface. Living underwater is possible, at least for a short period of time. But with modern technology, it’s a wonder why greater efforts haven’t been put into finding a way which humans can exist and live beneath the sea’s surface.There are a number of arguments which support research into underwater habitation. It could significantly help with the problem of over-population. Residing below the waves would also provide protection and safety from various natural or man-made disasters, such as tornados and earthquakes and so on , but comes in with greater challenges as well.
Suitable quality breathing air is one of the most critical environmental conditions along with others needing for human physiology to continue their live. Underwater habitat needs to meet these requirements to allow humans to live. Along with meeting these requirements, researchers need to concern about the physical environment (pressure, temperature, light, and humidity), the chemical environment (drinking water, food, waste products(management), and toxins) and the biological environment (hazardous sea creatures, microorganisms, and fungi) of underwater habitats , communication and requires huge funding.
The life underwater is no less rich than the life on the surface of the water or the terrestrial life. The aesthetic beauty of underwater life is one of the prominent features. Living underwater full time is not fully reasonable in the present time, but it could become a very logical option in the next 10 to 15 years. We just need to hope that underwater technology continues to develop so that we can live under the sea. But along with these we also need to think about to do all these things effecting the environment as less as possible. I personally feel , It is better that we live on earth's surface than colonizing oceans , it is high time that we consider problems like global warming, increasing population etc and control them .

ReplyDeleteLife underwater is one of the most exciting things in the world. The same is characterized by plants which exist in a wide variety, aquatic animals which are both dangerous and sober, microscopic organisms which are the basic food of the animals. Even the largest mammal in the world, the blue whale, resides in the oceans. Thus, life underwater is a part of the life on earth.
The underwater life also provides man with a variety of minerals and other resources for consumption.Besides that, other side effects of living in underwater bases include paleness and reduced vitamin D production, from lack of exposure to the sun.
The most obvious and problematic issues with creating cities underwater would be putting in place emergency evacuation plans, and also regulating air supply and humidity. Finding an independent energy supply is another challenge, however, there are plenty of sustainable options, including utilising wave action and placing solar panels, or wind turbines, on the surface.
Therefore i conclude that living in underwater can be possible only for very short period of time.

In today's life, global warming becomes a major problem. It is the main reason for the melting of ice. so,may be after 100 years all the world's ice will be melted and the land will be disappeared. So, we have to move to underwater colonies. I trust It would be quite interesting. We have to swim instead of walking and the transport system also changed.we can move fast than walking. Scientists may found another way to breathe under the sea. There will be no pollution in the underwater colonies. Our food habits will also be changed. Electricity will be brought in another way. In Disney movies I saw some underwater colonies and I eagerly waiting to live in the underwater colonies.

There was an idea,not too long ago:
Humans can start occupying the blues of the earth rather than just filling up all of the greens.
We know that the world population is rising and mother Earth hasn't got enough to feed every upcoming generations.People build habitats at almost every lands which are unoccupied and suitable for life.We should remember that we aren't the only living things on land.To preserve the ecosystem,the other animals,birds should also their equal share in land resources.The another reason humans should try having a aquatic life is Global warming,the root cause for almost every other catastrophe that could happen.It has lead to melting of ice in the polar regions.
Scientists have actually made researches in building underwater habitats for humans to maintain ecological balance in the future.We could also think of finding outer space planets with living environments like in the movie 'Interstellar' but it's a long shot and highly impossible.But living in a place built under the seas isn't impossible according to the researchers and they even have prototypes ready just in case.
When we look at the life underwater,it could be actually peaceful and more safe than the polluted environment we are living now.We have polluted the oceans too,but undoing that for the survival of life is not too much of an ask.We could take all we need for years to come before going underwater and start a new life in an almost new world.Maybe there will be advancements in technology to finally convert saltwater to groundwater,so that we can actually live there till death.But as modern generation,we should learn to let go of all the facilities we get in land,like internet-based features,mass media,etc. as such communications underwater could disrupt the marina life.This again brings an imbalance in the ecosystem.
Thus,the only way to sustain human life in underwater is to live as colonial habitats with not too much developed but simple methods of livelihoods,similar to the life we had centuries ago.So if other living things should adapt according to our benefits,then we should learn to adjust living in such habitats for a lot more generations.

Human activities are at the root of these phenomenon. The industrial revolution, Carbon dioxide and other green house gas emissions have raised temperatures,even higher in the poles, and as a result,glaciers are rapidly melting,calving off into the sea and retreating on land.
If we think that switching our livelihood into Underwater habitats is feasible in the near future, then we should also think how efficient would it be when compared with the present.
Cost and resources :
Even though an underwater colony is cheaper than the Martian one, it would still be horribly expensive to build and it will still almost certainly be dependent on resources and services from land. A fully self-sufficient underwater city looks like science fiction than an economic reality.
Medical :
Medical care would be much harder to receive , especially in the earlier days of colonization. The psychological effects on a human being , stuck far underwater away from the sunlight would also make a community of people , with depression and anxiety issues.
Sewage system :
We should construct a proper sewage system that doesn't affect the sea creatures . The waste should be treated well before disposing.
Human nature :
It is the nature of human beings to conquer and secure their necessity and belongings. So from this perspective, what could actually happen is, we would divide the sea into different countries and band together for common defense against the dangerous other thereby destroying the resources available.
To conclude, I would say,a floating city would be really efficient than the underwater colony. A floating city will get drinkable water from rain,sea and air. Its energy sources will be sun and bio- fuel. The cost and resources of construction and development also look feasible.
With the upcoming technology and inventions,even the underwater concept would soon be a reality.

World over, the human population is exploding at an alarming rate and our various environment-deteriorating activities have resulted in drastic changes in the climatic pattern. This has in turn led to the melting of ice-caps and other undesirable consequences. This scenario is making it difficult for humans to survive on land. The alternatives are either forming space colonies or going underwater for survival.
With rapid technological innovations, underwater colonization is something that is not far behind in time! The first question that arises is “How do we go about it?”. One of the ways is clearing selected pockets of seawater, using bubble technology wherein seawater is sucked out, space created and eventually filled with oxygen and other necessary gases. Eventually many small pockets can be clubbed together to form a huge colony in the size of an existing city. For the purification of air inside the pocket, some artificial pores can be created on the surface of the pockets, that permits only the diffusion of dissolved oxygen from the seawater. As land area under the oceans, is more than that on the earth’s surface, this technology can be used to create more underwater colonies. Transportation needs can be met by connecting the colonies through tunnels. As far as food is concerned, cultivation also needs to take place as we can’t just survive on the marine organisms and edible underwater plants. Plant gene mutation can be experimented with, to introduce new characteristics in plants that enable their survival under artificial light.
The main challenge lies in overcoming the various hurdles and creating an atmosphere that meets the needs of human physiology and provides suitable environmental conditions. Once that is done, all the other basic factors like electricity, cultivation, transportation etc can be incorporated. Only time will say how far this will be fruitful and all we can do from our side is meticulously work for it!

Having said that, as a result of Global Warming, the glaciers are melting fast which could result in disappearance of portion of lands. Also population has been increasing at high rate. Hence, we humans are searching for alternative solutions like Colonization in Mars. One such solution is Underwater Colonizing. People are thinking of this idea and doing research on this for years.
Now speaking about underwater colonies, our first thought would be that this idea can be the best solution we are looking for! The reference to the idea of underwater colonization can be seen in some video games or some movies. But as we continue thinking, we will know implementing this idea has many problems , for which solutions we may or maynot arrive at.
So, the foremost problem will be oxygen as we humans aren’t capable of taking dissolved oxygen like aquatic organisms. The oxygen cylinders can provide a solution, so we have to carry those cylinders with us everywhere we go. When we speak about underwater, we must think about the high pressure it exerts. I don’t think human lungs can handle gases of such high pressure. Hopefully, there can be a solution or we may find one in the near future. Still there are lot of problems we need to look at.
Our way of living would be totally changed when we go underwater. Like foodstyle, transportation, way of communication, etc will be changed. So we have to depend on seafoods. For transportation, we might have to use vehicles like submarines. Communication will get difficult underwater. Some of these problems can be solved if we can construct some dome like structure which can meet our physiology , where we get enormous oxygen and do things that we do here on Lands(Say Walk).Another thing we have to think about is that there are many organisms underwater whose ecosystem could be disturbed by our arrival there.
If we find solutions to all the difficulties with our technology, we will be able to live in the exciting world of underwater. Maybe, we can adopt to the situations there by achieving small change through generations. But, generally everyone of us would prefer living on land ( which we are well adapted to do)…

ReplyDeleteUnderwater colonies would be a great solution for spacious living. It would help us discover life from a new perspective and sturdy about ocean. How humans breathe underwater, and the depth of the structure are correlated, dictating how the structure should be created and the quality of air, humans will breathe in their underwater city.
First and foremost, humans should not build a colony and deeper than 1,000 ft or 300 meters.Anything deeper would cause serious risk to the structure and the people living in the habitat.
Residing below the waves would also provide protection and safety from various natural or man-made disasters, such as tornados and earthquakes
The most obvious and problematic issues with creating cities underwater would be putting in place emergency evacuation plans, and also regulating air supply and humidity. Finding an independent energy supply is another challenge, however, there are plenty of sustainable options, including utilising wave action and placing solar panels, or wind turbines, on the surface.
In today's world where there's overpopulation, available land space keeps on decreasing . This results in encroachment of forests and pollution of nature and natural resources. With all the ice melting land masses will disappear and moving underwater colonies sound like an exciting prospect but there are lots of problems associated with which doesn't make it worthwhile in now but maybe in the future.
ReplyDeleteWell the main problem is technology and infrastructure. We know more about space than our oceans. If we are to survive underwater we need infrastructure which can withstand a lot of pressure and undersea currents and we have must have the technology to build it. This is just a few meters deep into the ocean. As we move deeper the situation changes as there as different phenomenons which occur which we do not fully understand. There are underwater volcanoes,
earthquakes, shifting ocean beds which pose a threat and one which could destroy the colony in a flash.
The next problem is livelihood. We as humans can adapt in most dire situations and habitats. Sure humans can survive in an infrastructure underwater but many factors come into play like pressure regulation and oxygen supply. The infrastructure should be built to almost perfection because even a single leak in it could endanger the lives of everyone in the colony.
But with all the problems, underwater colonies seem like a viable solution to tackle overpopulation. Underwater colonies sound exciting but can mankind change his normal habitat from land to ocean?

Global warming and climate change have raised alarm bells and this is a wake-up call to all of us. We've done all we can to damage this planet and its high time we look out for other possibilities like space or underwater colonization.
The concept of underwater colonization might seem bizarre, but it is a point to take into consideration. The very idea of civilization has evolved over centuries and starting this process again on a completely different planet is going to be a Herculean task. Imagine, on the contrary, a life in the underwater world. Industrialization is booming, with few notable studies and initiatives being carried out along the same lines.
Before implementing such thoughts, however, there are few severe problems to contemplate upon. Looking at the history of the geography of the world, most countries are formed by invading the land. Right from ancient times; the conquest of land symbolizes power and authority. With underwater colonization, there won’t be any distinct boundaries which segregate and hence it would become extremely difficult to control gain over territory.
Secondly, at greater depths, withstanding pressure becomes intolerable. It is therefore necessary to construct the shape of structures and infrastructural sites in such a manner that it can endure elevated stress. This issue can be tackled by constructing spherically shaped structures as sphere with minimum surface area can withstand massive pressures, but this is undeniably a challenging task for the architects. Corrosion is another issue which needs to be resolved. If not handled properly, it can lead to huge economic losses and may destroy the property which will have an adverse effect on the lives of people. Galvanizing or electroplating won’t be sufficient. We have to find newer means of Nano technological ways that can cope up with this problem. Finally, with underwater colonization, waste management is going to be arduous. Ocean-cleaning sea bins that can gobble up plastic wastes could be constructed to efficiently recycle and treat non-biodegradable wastes.
Considering all these factors, underwater colonization is psychologically challenging. We can expect this to become reality in the near future with the advancement in science and technology. As humans, however, we need to retrospect on the drastic destruction we have incurred and take conscious steps to guarantee a peaceful survival.

The idea of underwater colonies was once a fantasy. But that's what is going to be the reality in the upcoming centuries. Considering both the aspects of population density rates and global warming, we will end up in giving up our lives on land and going into the deep blue oceans. The living planet with two thirds of it's portion covered with water would soon transform to a larger extent. Underwater cities is not a complete fantasy, at the same time it's not that easy. Proper facilities have to be arranged without damaging the marine ecosystem. The marine ecosytem already has issues like ocean acidification(pH imbalance of oceans), coral reef dying(coral bleaching), mercury pollution and the marine lives dying because of over-fishing. The oxygen levels of oceans also have to be considered. We have such problematic issues in the oceans, despite we staying on the land. What if we migrate into the oceans now? Yes, we ought to think. A proper ecosystem would mean a healthy life for all species concerned with it. Before the glaciers melt and before we migrate into the oceans, these kind of problems have to be fixed properly.
Basically we all would need oxygen cylinders to breathe properly, typically like underwater divers. Life protecting cylinders have to be manufactured in billions without any malpractice to meet the requirements. Next, ecah of us we would need a proper living space.So this would lead to a brand new underwater world map!!! Funny though!!! The next requirement would be a proper diet. We can't cook there!!! We need to go back to nomadic times where we ate raw food. By then 'raw sea food'. We will have to hunt and gather food for our living. The marine predators are wild beyond imagination. Hence personal safety is next. To be more specific, our safety without damage to marine life should be the ultimatum.
These are the basic requirements. Moving one level up, technology comes into consideration. Communication is not that easy under water. We will have to communicate by means of ultrasonic and infrasonic waves like whales and dolphins do. Appropriate devices have to invented and tested at all depths. But we cannot acheive every single technology as we did on land.
On the whole, we can't say a yes or no to the question "can we have underwater life?" If glaciers melt enormously and water levels rise rapidly, we need to adopt to such life.We can control global warming and do every little thing to maintain this land area. But if situation becomes worse, arrangements have to be made and lives will turn tougher. Lets get prepared in all the aspects (especially mentally) to survive on the planet.

Human activity is playing an increasing role in the melting of glaciers, Austrian and Canadian scientists have found.One of the most disruptive effects of climate change, glacier retreat leads to rising sea levels, landslides and unpredictable availability of water downstream.
Meanwhile, a separate study found ice discharge from the Antarctica could raise sea levels by up to 37cm this century, more than previously thought.As people continue to pump greenhouse gases into the air from burning fossil fuels, this trend is set to continue,“Without anthropogenic forcing, the glaciers would stabilise at slightly higher elevations, and eventually stop losing mass.If greenhouse gas emissions continue to rise at their current rate, they projected ice lost from the Antarctica could push sea levels up by 1 to 37cm.This would immerse the land around Antarctica even Australia..
If this state continues.... obviously we are pushed for a underwater colonization..is this so simple to deal with underwater colonization ?!...
Most early underwater habitats lacked regenerative systems for air, water, food, electricity, and other resources. However, recently some new underwater habitats allow for these resources to be delivered using pipes, or generated within the habitat, rather than manually delivered.
An underwater habitat has to meet the needs of human physiology and provide suitable environmental conditions, and the one which is most critical is breathing air of suitable quality. Others concern the physical environment (pressure, temperature, light, humidity), the chemical environment (drinking water, food, waste products, toxins) and the biological environment (hazardous sea creatures, microorganisms, marine fungi). Much of the science covering underwater habitats and their technology designed to meet human requirements is shared with diving, diving bells, submersible vehicles and submarines, and spacecraft.
The idea of humans living underwater may is not as crazy as you think. An idea reserved for video games or sci-fi films, underwater cities are a viable solution for humanity in the distant future.
It makes sense to go out and colonize Mars, but the ocean is just as livable and is far closer to home. As you probably already know, the earth is 71 percent water. This could be prime real estate for future generations.
Living underwater does pose its host of challenges, like freezing, immense pressure, and a lack of oxygen. Not to mention, underwater living can wreak havoc on your body.
However, there are promising new horizons in the world of underwater living that could tackle these issues and have you or your future children living comfortably in the coming years.

When I close my eyes and imagine a life underwater..it reminds me of my childhood days.. where I 'm the most excited person about this idea inspired by cartoon series.. Well..as a grown up ,I come to understand that it really requires a lot of technological development and acceptance.
As we all know earth is covered by 3/4 th of water bodies and ice is melting rapidly...underwater colonisation would be a great solution in future to control the population growth which is increasing at an alarming rate.
It really requires alot of scientific developments to manage the oxygen level and a high pressure under deep water. These colonies must be designed thick enough to withstand such high pressure.
As there is an abundant source of sea food..they would act as a main source of food..whereas planktons,canned ,preserved and dehydrated foods would act as an alrernate source.Cooking under water is although possible..it must be avoided because fumes may seem stronger which can lead to suffocation.
Though we can escape from natural disasters like earthquakes and alarming issues..such as global warming... there is a chance of having equal chances of natural disasters that could happen underwater and risks of the breakage of walls of the underwater colonies.
Unemployment would remain an unsolved problem even underwater.Though the viability of mining rare earth minerals are possible it could act as the only major employment for underwater survivers.
Depending on the size of the colony,human waste could be treated and released into the environment or cooked down to a fine ash.
Underwater colonies can satisfy the basic needs of human beings but it could not be an independent one..which always need a backup from the environment we live in.
Though human beings can adapt easily..they must be trained to a perfection and sent to underwater colonies after agreeing to certain terms and conditions only then this plan can achieve success.

With environmental problems on the rise, underwater colonization might be the only way of escape. Living underwater does pose its host of challenges, like immense pressure, and a lack of oxygen. To colonize any uninhabited environment, the primary requirements are shelter and food. Although seafood maybe in abundance, it might not be rich in all nutrients. This will affect the required balanced diet for a healthy sustenance. But few years down the lane, even that reduced nutrition will be exhausted.
There have been developments in the underwater construction which seems promising. The main principle which is to be considered for underwater construction is ‘The Law of buoyancy’. Buoyancy or upthrust, is an upward force exerted by a fluid that opposes the weight of an immersed object. The relationship between buoyancy and self-weight is an important criteria to be analyzed. If buoyancy of the structure is greater than the self-weight of the same, the structure would float. Likewise, the structure would be submerged if the scenario is vice versa. These two properties can be used to construct floating and submerged structures to make colonization possible underwater.
On a longer haul, it is imminent that human species will undergo evolution with respect to the surroundings and who knows, maybe humans can respire underwater.

In a world where population is rising at an alarming rate,we humans must find a better solution to accomodate more people. We tend to pollute our mother nature resulting in global warming which causes disappearance of lands and melting of ice.Since our argument is not about reducing pollution,we assume that our world has already been polluted enough that there is no more place on earth for a sustainable life.So we think of moving underwater and building human colonies.This could be possible in the near future, given the rate of development of our technology.But there are numerous constraints when it comes to this. For example,we must think of a way to produce oxygen since the plants need a sustainable environment to produce it.We must also consider a way to harness electricity and supply them.There should be a transport facility which produces no pollution to the environment.We couldn't have train or air transport so we couldn't travel anywhere fast.
Moreover we have to eradicate 60% of the marine animals to build human colonies.We should have that in mind that this world is not only meant for humans.If we build underwater colonies there won't be a concept of country or state we all must live as one group.If suppose some dispute arises between countries like India and Pakistan then using explosives and wepons could cause a complete collapsing of the colony.
Will there arise better technologies to overcome these constraints is a big question mark.That would be the beginning of a new era and it might take centuries to completely develop a technology that is so advanced to survive in such environment

ReplyDeleteSuppose we assume if people try to migrate to another country their adaptation to that particular environment needs more difficulty their language, food, cultures are different. If we take this as concern people hard to find it living underwater. We need a lot good technology to compensate the basic right needs of the human beings living like air,water,food,shelter,etc. God given us with a special adaptability in any every situation but whereas the other species are not. We the human can adapt any situation. Thought if we had a situation like this we can mangae. But the question is to find the technology before the world could go in such a disaster. If this is the case the underwater living, we may have a danger to the eco system already present there. We don't have the rights to take over one's living and it's habitant. There may be an undefined disease over there,if we could live. We have the solution for that. The climate could only be chill all the time. But we are warm blooded species where we find difficult to maintain body temperature over there and the transportation from one place to the other place could be so difficult because the movement under the water is less when compared to the air. Where the molecules are way far eachother so we could move fast. If this is the case would we ever thought of living inside the rocks or mountain? This also could be possible if we find a way to enter the solid object. We have only find a way to go through the liquid and not solid. So moving on to the topic the as Darvin said,"Survival of the fittest". We could take the dinosaurs age they are the fittest of all kind in that particular era. But what happens is that they went off from the world. What I am trying to say is that human could be called as fittest now. What he has extra than the dinosaurs is that he has knowledge. Able to make decision on his own. Concluding by saying that this is possible for a human to live in any environment with a proper technology. So people never find hard for the living. Instead speaking of taking over the other ecosystem people try to save our own environment.

As sea levels and populations rise, and we begin to run out of space on land, some pioneers think that we should begin to colonise the oceans.
For living in under water, we have to create ideal water displacement. We can use the material which is uses in the submarines body and also the glasses for windows.
There are many advantages to underwater living. You would have beautiful views of underwater life. There would be relatively low maintenance besides cleaning windows . You could grow seaweed, have desalination to get fresh water, a current turbine to generate power, and have a fish farm to get meat. You could pump in air from the surface.
The main disadvantage for living underwater would obviously be the cost.another disadvantage would be tougher access to stores and other facilities. This could be fixed by having underwater communities where a lot of underwater building are connected. The last disadvantage I can think of would be transportation. Only top level submarines can get over 30 mph and the average ones max out at 30 knots.
prevention is better than cure. We haven't learn to live in under water, If we reduce the global warming.

As a result of increased global warming due to pollution or the presence of excess co2 in the environment it is told that the ice caps are melting and that humans have to colonize in the water bodies.
Colonization in water bodies is something that every human being has thought of at least ones as 71 percentage of our earth is covered with water.
But this process to process to happen is not that easy as it sounds.As there is something very vital for the human race to exist that is oxygen.Which is very difficult to provide underwater .Our technology should highly advanced provide oxygen underwater.
Moreover the pressure underwater is high. Which is highly dangerous. So pressure reducing devices have to be made.
There is one more disadvantage in colonization underwater.ie the humans have to be kept safe as the humans and underwater animals are supposed coexist
Therefore underwater colonization is a very difficult process

Change. Some are afraid of it. Some embrace it. Humanity as a whole, though, has been accepting of change from a long-term point of view. It is forced to because nature constantly changes, more recently because of human actions, ironically. Nature changes but change is nature.
The cause of any global large-scale problem can most probably be traced to overpopulation, directly or indirectly. Underwater colonization has been touted as a possible solution but feasibility concerns have been fervently raised. The potential of oceans is is unequivocally high, albiet, and the following arguments illustrate why it is so.
First off, the transition has to be gradually done. Humans can't move underwater overnight. Appropriate environments have to be created to imitate land underwater. Confined spaces on the ocean floor have to be covered with some sort of glass to prevent water seeping in. Normal oxygen can be breathed in without the help of any tank.
Secondly, from a territorial perspective, nations will have to work out compromises. Conflicts will have to be prevented. International organizations will have to broker peace treaties. Landlocked countries will also need to be accounted for.
The third and final argument for ocean colonization is regarding research and development funding. The ocean has so much untapped potential. The US government spends 200 times more on space exploration than its ocean counterpart. Scientists need to be funded to research and study the ocean as an option for habitat as opposed to space.
The arguments provided above are very much utopian where everything works out as planned. Realistically, there will be many obstacles. This is why, in a practical sense, any framework drawn up in favor of ocean colonization must be a long-term plan involving multiple centuries.

As population is rising , the population density raising.so we have to find a way for living .There were several researches going on this. As the earth is getting warm,the sea level is increasing . Already the water body is 71%.this global warming will cause further increase.So finding a way to live in water is a may be good solution.
At a sudden ,we cannot change our habitat into underwater.So we have to
create a suitable atmosphere for human beings.Already we have ocean to drinking water technology. So water is not problem.But the cost to implement this technology will be more. For food, we have fishes and sea ferns,mushrooms and plants, sea animals.So food as is not a problem.But these foods will have very less nutrition. this will leads to ill-health. Wastes can easily disposed into the water.But since we live in water and the wastes can spread from area of dumped other place ,it will contaminate the whole water body and atmosphere.In the case we live in water there is no light at all, so we have to live in ultimate darkness . we must depend upon some other source.If we use bulb we need power.For that we can use electricity from sea waves and tides, solar panel on the surface of the sea.
But still oxygen which is essential for our living very less in oceans and we cannot breathe directly from water.If we use oxygen through container, we need a large tank to store the oxygen. we cannot live by swimming or floating.we need a house to live. we may fit
big glass container under water where no water can intrude but ocean soil is unfit for construction works. But under water the pressure is very high the glass would crack under such a pressure and it is not possible to make such a large glass container.
We have to consider the countries which are not having any sea or ocean bodies and there
will be clash between countries for specific place which they need occupy.This may lead to third world war.After all the governments are not showing interests on this. they are interested on living in moon and mars and they are not giving any funds for these researchers.
We will certainly find solution for this,but it will take several centuries to accomodate
these technologies but by that time human will under go evolution to live in water.
Yes, the ice in the poles are melting and the land we live now is disappearing. In that situation we have to live in underwater colonies. The question is " Are we ready for that?" , probably sooner.
ReplyDeleteWith today's technology we can built underwater train tunnel. Its not deep under water but in the middle with a float above the water. The tunnel is not built under the water, it is built in the land and then sunk under water. But for us to colonize under water we have to sink a big city, well that may be feasible in the near future.
Even if we are able to sink a city, there are other consequences like fresh air, drinking water, food, etc., with all these consequences we have to find a way to continue our race under water.

DeleteThe realm below the surface of the water where the water remains in a natural state like in oceans, ponds, lakes etc. form the underwater. Almost three-quarters of the surface of the Earth is covered by water. Humans are engaged in a number of activities conducted underwater like scuba diving, research etc. But however, almost a majority of the underwater still remains unexplored and is expected to have several million undiscovered species of flora and fauna.The life underwater is no less rich than the life on the surface of the water or the terrestrial life. The aesthetic beauty of underwater life is one of the prominent features.Life underwater is one of the most exciting things in the world. The same is characterized by plants which exist in a wide variety, aquatic animals which are both dangerous and sober, microscopic organisms which are the basic food of the animals. Even the largest mammal in the world, the blue whale, resides in the oceans. therefore, it is necessary that keep a good balance of their life. If sea water and ocean water are polluted then it affects the aquatic life. Many aquatic animals face death because of polluted water. As water is the only source of oxygen they have, if this source is polluted then for sure it will affect their life.it needs a huge research to understand the life cycle of aquatic animals. Aquatic life is too complex. Many animals in aquatic life are not defined yet and there are many new species that are born each day. They are not discovered yet or not specified or not named yet. The vastness of aquatic life is the reason that it is to maintain a deep knowledge of aquatic life.
