Imaginez si les humains pouvaient vivre au fond de l'océan ! Nous aurions des villes entières sous-marines avec des dômes et des tunnels, entourées par des créatures marines. Cela pourrait aider à résoudre le problème de surpopulation sur terre, en nous offrant un nouvel espace pour vivre. Mais ce ne serait pas facile—construire des habitations capables de résister à la pression des grands fonds marins serait un énorme défi. Nous devrions également trouver comment y acheminer de la nourriture, de l'oxygène et de l'énergie. Cela semble vraiment cool, mais coloniser le fond de l'océan nécessiterait certainement une science et une technologie sérieuses !

00:00Let's assume that everyone agrees and that all countries start to invest billions of dollars in this project.
00:07That of colonizing the bottom of the oceans.
00:09The question is, why would we need this?
00:13Probably for the same reason that undermines the possible colonization of Mars.
00:17To save the Earth from overpopulation.
00:19Why would we settle on the Red Planet if we can live under water just as well?
00:24It costs less, it's less dangerous and above all, it's not very far from home.
00:28No need to lock yourself in cryogenic capsules for years to wake up hundreds of millions of kilometers from your planet.
00:36It is much more practical to take the elevator to go down to an underwater city and enjoy the magnificent aquatic landscapes.
00:43In addition, life on Mars could cause us serious psychological problems, panic, stress, etc.
00:50What to do when you realize that you will never be able to go home again?
00:53It is better to live under millions of tons of salt water.
00:56A very good reason to choose this option is that we need more resources.
01:01The Earth currently has about 8 billion inhabitants.
01:04Some experts think that when this number reaches 10 billion, the world will start to lack food, fresh water and fuel.
01:12Agriculture and other industries will simply not be able to develop as quickly.
01:18Resources will run out and people will have to find a solution to survive.
01:22Colonization of the oceans is an ideal solution to this problem.
01:28First of all, we have very little information about the ocean.
01:31We have studied space much better than the bottom of the seas of our own planet.
01:35It is very likely that huge reserves of fuel are hidden under the seabed.
01:40Secondly, it is possible to reduce the load of our planet by about 50% if we settle in the ocean.
01:48Thirdly, there would be no logistics problem.
01:51The transportation of food, necessary equipment and building materials would only take a few hours.
01:57And if something was damaged along the way, we would just have to quickly go back to the surface to replace it.
02:03Sending objects to Mars is much more complex and expensive.
02:06Imagine that halfway, millions of kilometers from Earth, a spacecraft breaks down in the space ship carrying supplies.
02:14It would then have to wait several years before a new delivery.
02:18But above all, colonizing the oceans would be fighting against natural disasters and cataclysms.
02:25Volcanic eruptions, radioactive winters, earthquakes, tornadoes and floods.
02:31We can easily survive any disaster underwater.
02:34Yes, there are also volcanoes at the bottom of the oceans.
02:37But the consequences of their eruptions are not so dramatic.
02:40The water immediately cools the lava and prevents the ashes from spreading.
02:45We would never suffer again from the devastation caused by fires.
02:49No more burnt forests, no more polluted air.
02:51And speaking of air, there is a lot of oxygen in the ocean.
02:55More than half of the planet's oxygen reserves are reconstituted by the sea thanks to algae and phytoplankton.
03:01So don't worry, we can breathe very well.
03:05It's all about knowing how to do it underwater.
03:09When humanity decides to go through this stage and start colonizing the ocean,
03:13we must first adapt our body to high pressure.
03:16This is what we call saturation diving.
03:19Before going down to the depths, you must inhale compressed air.
03:23The nitrogen and oxygen dissolve quickly in your blood and exert pressure on your body from the inside.
03:29At the same time, the water exerts pressure on your body from the outside.
03:33In simple terms, your body finds a balance and you don't feel sick.
03:37Divers use this method when they explore the seabed.
03:43Therefore, when humans begin to colonize the ocean,
03:47they will dive equipped with compressed air bottles and oxygen masks.
03:51The main rule is to go up slowly to the surface.
03:54You have to wait for the compressed air to completely dissipate in your body.
03:58If you go up too fast, you will feel an intense pressure inside your body.
04:03The nitrogen will spread in your veins like the bubbles of a fizzy drink shaken vigorously.
04:10After being adapted, we will begin to build cities, roads and stations
04:15that will allow us to transport people from the seabed to the mainland and vice versa.
04:20This should not be too difficult,
04:22because we already have the necessary technologies for a sub-aquatic lifestyle.
04:29Welcome to Aquarius Reef Base, located in the Florida Keys National Marine Sanctuary.
04:34It is a small laboratory where 6 people can live for 10 days.
04:38The scientists who work there study coral reefs, marine plants and fish.
04:46The laboratory does not look modern.
04:48It looks like a rusty bathyscaphe, invaded by shells and other underwater objects.
04:52To create more beautiful buildings, people will need new underwater construction technologies.
04:57Let's imagine that global colonization has begun.
05:02Engineers use durable stainless steel and other materials capable of resisting high pressure.
05:09With the help of a loader, they bring down to the bottom of the water
05:12everything that is necessary for large-scale construction.
05:15Stations equipped with this type of device appear in all seas and oceans.
05:23Workers build, on the mainland, huge submarine workships
05:27that large ships then move to the stations.
05:30From there, they are lowered, and divers are helped by robots,
05:34install houses and other facilities at the bottom of the ocean.
05:38Each building is a kind of giant submarine with many apartments.
05:42From the inside, they look ordinary,
05:45except for the landscape that can be admired from its window.
05:48To reduce waste emissions,
05:50engineers build huge high-pressure treatment capsules in each city.
05:56But people continue to want to live near the coasts
05:59in order to have easy access to the mainland.
06:02Unfortunately, this leads to pollution problems in these areas.
06:05Tunnels are built connecting the stations to the mainland.
06:08Inside, high-speed trains run.
06:11It's a bit like an undersea metro, but much faster than those we know today.
06:17Now, people can move away from the shores and live in a cleaner environment.
06:25Once the big work is done,
06:27humanity can start to live more comfortably in the underwater cities.
06:31Scientists create filters to quickly purify seawater.
06:35And everyone has a tap that takes the water directly into the ocean
06:39and turns it into fresh water.
06:41Builders also install filters capable of extracting oxygen from the water.
06:46Electricians create underwater mills to produce energy.
06:51To get out of your home,
06:53you have to put on a spacesuit and compressed air bottles and go through a drain.
06:57People swim between buildings and talk to each other on the radio.
07:02To move around quickly,
07:04car manufacturers produce small buildings
07:07with locked cabins and powerful propeller systems.
07:10Finally, engineers create large domes
07:13where you can walk around and breathe fresh air, like on the mainland.
07:18Large clothing brands develop fashionable diving suits
07:22and practical accessories to move comfortably underwater.
07:26For example, you can attach a small heater to your clothes
07:29so you don't get cold when you swim.
07:31You can also put on larger palms
07:34with the logos of your favorite brands engraved on them.
07:38To make this lifestyle as comfortable as possible,
07:41scientists and biologists create masks that work like branches
07:45and provide people with the oxygen they need.
07:49Over time, the constant exposure to high pressures
07:53changes the physiology of the human being.
07:55In the water, we have to make more effort to move.
07:58People who often leave their homes lose a lot of calories.
08:02They become thinner and their muscles strengthen.
08:06Look at the swimming Olympic champions.
08:08Today, almost all underwater citizens look like these athletes.
08:12The temperature of our body decreases
08:14and evolution slowly turns us into cold-blooded creatures.
08:17The lack of sun makes our skin paler
08:19and we begin to look like amphibians.
08:23We learn more about the creatures of the deep,
08:26like the giant squid and other monsters.
08:28Almost every month, scientists discover new species.
08:32But at the same time, many species of fish disappear
08:35because of human activity in the ocean.
08:38The extraction of natural resources from the seabed
08:41strongly pollutes the aquatic environment.
08:43To reduce the burden on the planet,
08:45humans decide to colonize the sky.
08:48But we will address this subject in another video.
