If the sea was ten meters deeper than it is now, would humans still be able to survive?

No, you want to increase carbon dioxide just a little bit, and the survival of humanity will be affected, if.

How much air does a 10-meter sea absorb at a depth of 10 meters? How will the climate change? It's unimaginable!

Don't you know that the earth experienced a great flood in ancient times? The flood was said to be 10 meters higher than the current sea, but humans still survived. Do you know why there is a story of Dayu controlling the water in our Chinese history books?

And in the Bibles of Europe, there are stories about doves becoming messengers of peace due to the great flood? Are there any claims about prehistoric floods in India, Egypt and other countries? This is enough to explain that the sea water is 10 meters higher than it is now, and we humans can survive.

Historically, the height of the sea has varied greatly. Just 8,000 years ago, during the last glacial period, the sea froze into ice at the poles, the sea level dropped dramatically, and on the east coast of Asia, all of the Bohai Sea, the Yellow Sea and most of the East China Sea were exposed, and the Yangtze River was then estuary in today's Okinawa Trough (now the boundary between China and Japan at the eastern end of the continental shelf in the East China Sea). From this point of view, a 10m rise in sea level is not a big deal, at most we can build the pier 10m high, and the coastline will retreat a little, or the embankment will be higher.

Probably not. But other species may not be the same, and they may evolve into cockroach people!

Yes! Don't underestimate the survivability of human beings!

I think that in addition to the loss of land area and the extinction of some organisms, human beings will survive! Do you think that the treasure that nature created after 4.2 billion years will naturally be willing to let it go extinct?

The question is too simple.

The landlord should think like this, from ancient times to the present, the sea water has been more than 10 meters.

The result?

Humanity is not extinct, but humanity has evolved.

You mean the sea drops 10 meters at the bottom.

There is no impact, and there is no shortage of air.

What the hell do you mean?

Come on. Is it good to learn a good language?

At least the world's coastal cities are submerged, and humans can move to higher altitudes!

A 10-metre rise in global sea level could dramatically change the global climate pattern, and it's not as simple as a 10-metre rise in water at our doorstep.

Can you be so unconfident in yourself?

It's hard to say, have you ever seen the "Future Water World", which is to say that the future earth is full of water

A short tsunami can kill tens of thousands of people, but will a 10-metre rise in water be fine?

This kind of problem cannot be imagined.

There's so much to do with this question.

Earth-level problems cannot be compared to the amount of water in a cup.

It's going to have a lot of ripple effects, like the butterfly effect in South America.

I guess the scientists don't think you're either.

I'm sorry.

First of all, in order to achieve your ambition of "the sea is ten meters deeper than it is now", where did you get so much water?

A lot of times it's fun to make assumptions.

You don't know until you experience it!

The actual operating depth of the French diver's saturation dive in the Mediterranean Sea reached 534 meters, while the experimental depth reached 701 meters, which is the highest record in the world today.

In diving, the main problem to be solved is breathing. Freediving is all you need to do is breathe compressed air. However, as the depth of the dive increases, the pressure increases, and the nitrogen in the air will penetrate into the cells of the central nervous system of the human body, causing nitrogen anesthesia.

For longer or deeper dives, you need to have special equipment. This equipment is called scuba, and it ensures that the diver can breathe. This method of diving is called scuba diving, and the cylinder is filled with a mixture of the inert gas helium and oxygen, because helium has a much lower anesthetic effect than nitrogen.

Diving is not just a matter of breathing, another threat that humans face when diving is decompression sickness. Because every 10 meters of sea depth increases by one standard atmosphere. As the pressure increases, the body's blood's ability to dissolve air increases.

If the diver returns to the surface from deep water too quickly to decompress, the gas dissolved in the blood and body tissues will form bubbles, blocking blood flow and can be fatal in severe cases. Early divers had to gradually decompress in a decompression chamber before returning to the surface after completing their diving mission. The time to decompress is often more than twice as long as working underwater.

The solution was the invention of saturation diving technology in 1957. Divers first pressurize the cabin to completely saturate the gas in the body, and then they can work under the high pressure of deep water for several days, or even dozens of days, and wait until the task is completed to decompress the water at one time. This is because if you stay under high pressure for a certain period of time, the gas seeping into the blood and tissues of the human body will reach saturation, and as long as the pressure remains the same, even if the stay time is extended, the gas content in the blood and tissues will not change.

The deepest ocean in the world is the Mariana Trench, elevation: -11034 meters.

Deep into the deepest part of this trench is the goal of human ocean exploration.

On March 26, 2012, Cameron piloted the Deep Sea Challenger to a depth of 10,897 meters.

Augst's son, Jacques, Picard's father, drove the submarine to the deepest possible depth, reaching a depth of 10,915 meters. (Chen Order).

At present, the deepest personal diving record can only reach more than 300 meters, although the deepest diving record of military submarines has reached 10,000 meters, which is equivalent to the data of 11,034 meters deep in the Fichaz Abyss, the Mariana Trench in the western Pacific Ocean, which is the deepest point of the world's oceans.

Nearly 70% of the earth we live in is covered by the ocean, and the cycle of the ecological environment and human life activities are inseparable from this vast and mysterious ocean. At the beginning of the development of human science and technology, the mysterious marine environment has been continuously explored. As the depth increases, so does the fear and weirdness of the unknown, let's see how ecology and species change dramatically as the depth increases.

Below 300 meters below the seabed, we humans are completely accessible, and experienced divers can easily dive to this depth, even with protection, to touch the marine species we usually see. Finally, three hundred meters of sea, the pressure of the sea water has increased significantly, the average stress is equivalent to nearly six hundred pounds of human weight crawling, with the increase of depth, this sense of oppression will continue to increase the weight, three hundred meters has been close to the limit of human survival, no wonder more daring divers, will dare to step into the deep water. 500 meters underwater, it is the largest overlord blue whale in the ocean, they inhale the small fish and shrimp around them from time to time, and from time to time jump up to the fresh air on the surface.

At 600 meters underwater, it gradually enters the danger zone, where there is a fierce and cruel whale called the narwhal, which has sharp fangs and can devour the creatures around it, and even the famous ferocious Ocean King shark is no match.

The next kilometre of the ocean floor is the transition zone, which separates the shallow and deep seas. At a thousand meters underground, sunlight is difficult to penetrate, so it is always dark, and deep fear and pressure from the bottom can make you almost collapse. At a depth of 2 to 3 kilometers, you will find a terrifying lantern-lit anglerfish that uses a small lantern as bait to attract small fish around it.

The animals here have lost their eye function due to years of lack of light and rely on their amazing sense of smell to survive. It is the nest of the toothfish, which has evolved into omnivores due to the high water pressure and the lack of life and food at the bottom, eating everything that falls without a fuss. At an altitude of 8000 meters, the ocean reaches its limit, and almost everything crushes under pressure.

At 10,000 meters under the sea, it is pitch black and almost lifeless, except for a few amphibians floating in the water, shrimp-like crustaceans. It's just that the water pressure is threatening, but there is no light at the bottom of the sea at 10,000 meters. The darkness deepens the fear, and there are many mysterious creatures that humans have yet to discover, any of which could kill humans.

For 10,000 meters or even more of the seabed, it is still an unsolved mystery, I believe that with the continuous development of human science and technology, one day we will also go into this endless darkness to explore the mysteries of the ocean.

Humans have found in the deep sea, and there are basically no green leafy plants in the deep sea area. Crabs live 300 meters below sea level, with very large bodies of more than 4 meters, long legs, and small heads. At 1,000 meters below sea level, there is not the slightest light in any area, it is completely dark, and even living things become very rare.

At first, humans discovered all kinds of seaweed shells, some grass carp, and slowly discovered some large marine animals, such as turtles, and at the deepest point, some creatures that were long thought to be extinct, such as the megalodon.

Humans have discovered many creatures living in the deep ocean that we have not been exposed to before.

There is one place in the world that only three people have visited so far, and this is the deepest part of the oceans on Earth, the Mariana Trench, which is 10,911 meters deep.

No, the depths of the ocean are now the only clean areas on Earth!

Yes, in the Pacific Ocean or in the Atlantic Ocean.

No miles up to 3000m, at least not now.

No! I hope never to reach.

At present, the world record for diving without equipment is about 120 meters, and the record for diving with equipment is 332 meters, and the difference between the two records is 90 times and 30 times respectively from the seabed of 10,000 meters. It is impossible to dive to 10,000 meters naked, but it is possible to take a manned submersible.

10,000 meters underwater is equivalent to 1,000 atmospheres, but it is still possible to sit in a submarine, and several countries already have deep-sea submarines of this strength; It is definitely not possible to go down naked, and if you don't do it, the internal organs can be pressed out. Human respiration depends on the pressure inside and outside the body, the lungs can expand and contract under the action of respiratory muscles and thoracic cage, and the increase or contraction of the volume of the lungs is caused by the shrinking or increasing of the gas pressure in the internal cavity, and the atmosphere enters the lungs under the action of pressure. At the bottom of 10,000 meters, the pressure is very high, there is such a large cavity in the human body, and it cannot be adjusted freely, and the ability to hold breath is also limited.

The only place in the world with a water depth of more than 10,000 meters is the Mariana Trench, and there are currently more unmanned submarine detection studies in this place, and the number of successful manned submersibles is less. China has used unmanned submarines to detect, but for manned small submarines, China seems to have only explored more than 7,000 meters at present, and is the fifth country in the world to master the technology of large-depth manned deep diving after the United States, France, Russia and Japan. However, the strength of the United States is still the first echelon, and the great director James Cameron once successfully dived to the Mariana Trench in a deep-sea diving gear built by himself, and was the first person in the world to dive in his personal capacity.

Although this depth is very large, for the marine creatures that live there, the feeling of such pressure may be equivalent to the atmospheric pressure we are experiencing, those marine creatures have high water content, and many of them do not have inflated cavities in their bodies, which are used to fight against water pressure, and water is difficult to be compressed at room temperature.

No. Because the pressure at 10,000 meters underwater is very high, and the human body cannot withstand such pressure and will be flattened, so humans cannot dive to 10,000 meters underwater.

Human strength alone cannot be achieved. The two biggest obstacles when diving are oxygen and water pressure, the amount of oxygen consumed in the 10,000-meter dive is huge, and the strong pressure from the depth of 10,000 meters will directly flatten the person.

Humans are not yet able to reach the deepest part of the ocean floor, because the deep sea is super stressful and the light is insufficient, which is much more difficult than exploring space.

According to the data, at a depth of 10,000 meters at the bottom of the sea, the pressure per square centimeter can reach 1,100 tons, which is equivalent to putting 3 tanks on your fingers. In addition, if you go into the water with a person, you have to ensure that the pressure and temperature in the dive chamber are at a normal level, which is very difficult for today's technology, and it is not possible to guarantee safety.

In addition, there are many mysterious creatures on the bottom of the sea, and there are unknown dangers, and 10,000 meters under the sea is very terrifying. Not only mysterious creatures, but also surging magma and erupting volcanoes at the bottom of the sea, which can threaten diving machines and people at any time. So humans don't explore the deep sea.

The Mariana Trench, the deepest point under the ocean that has ever been explored, has not been visited by any instrument. Its depth is -11034 meters. In 1960, the American submersible Trieste dived to a depth of 10,916 meters, and no machine has broken the record so far.
