Thanks Wukong for the invitation!
Ocean Habitat:
Whenever there is a mass extinction on earth, the best preserved creatures are undoubtedly marine life. In other words, every time there is a mass extinction on earth. on the earth, the main reason is due to hidden extraterrestrial dangers ——Meteorites larger than 8 km hit the earth, preventing organisms exposed to the earth's atmosphere from absorbing oxygen, resulting in death and death. extinction. Since sea creatures are protected by sea water, smoke and dust cannot enter the sea water. Therefore, pollution has no impact on them and they all continue to live perfectly.
Therefore, in order to avoid the extinction of human beings, I suggest that humans go to live in the depths of the ocean, and now we should start building underwater residences to avoidter the next human mass extinction crisis. on earth.
Exactly:
To avoid disasters from outside the world,
Build a nest on the bottom of the sea.
If humans live in the ocean,
Ensure that natural disasters do not lead to extinction.
Because there is such a deep ocean and so much buffer insulation from seawater.
Because every time there is a mass extinction on earth, it is staged in the form of a flood. Sea water is salty and heavy. Sterilize and kill viruses. As a result, ocean creatures are relatively well preserved. Thank you for the invitation from the organization!
It cannot be said with certainty that marine life is relatively intact, because after several mass extinctions after the formation of the earth, most creatures were marine life. There are not many typespes of life. on land and marine life. The large base is the main reason for preservation.
The first life on Earth came from the ocean nearly 4 billion years ago, and land masses on Earth only began to appear About 2.5 billion years agofirst formed, volcanic eruptions and movements of the earth's crust were very active and the environment was very unstable. The small lands created were mostly rocks and mines, with no soil, no plants and no animals, just very simple primitive life. was born in the ocean.
From about 600 million years ago to 250 million years ago, marine life gradually became abundant and the land became relatively stable. Marine life attempted to settle on land, then amphibians appeared. /strong>. That is to say, from this period onwards, mass extinctions occurreduits one after another during the Earth's geological era, because the base of terrestrial organisms was relatively small, there were relatively few preservations during the extinction process. does not mean that marine organisms are on the verge of mass extinction.
During the Permian mass extinction that occurred 250 million years ago, approximately 95% of marine life disappeared and 75% of land life disappeared . period when dinosaurs began to dominate the earth. 200 million years ago the Triassic mass extinction occurred again, this time more marine life disappeared, including dinosaurs. Reptiles still dominate the land.
By the time of the Cretaceous mass extinction 65 million years ago, large land animals, including dinosaurs, had become extinct, leaving us with impression that marine life was completement preserved. . , but in fact, the extinction of marine life is not serious at all, but the inheritance of marine life is earlier.

Actually, we need to look at this question from another angle. For example, our human advantages, because we humans have developed our own uniqueness. system, we can adapt more quickly to changes in the environment. For example, if a person living in a cold area is suddenly thrown into the tropics, the temperature difference is very large, but the person still will not change. In a short time, it will adapt to the tropical environment. This is a powerful advantage humans have. No matter what changes occur on the earth, we can rely on scientific and technological achievements to slowly adapt. But living beingsants are different.
Life originated in the ocean, because we know that in ancient times, almost all living things on earth had their ancestors in the ocean, although those used on earth today There are countless living beings, but in the entire history of the earth, living beings today represent only 20% of living beings on earth. In other words, the remaining 80% of living creatures have disappeared. The extinction of living beings results from various natural disasters, such as super earthquakes, volcanic eruptions, environmental changes, Xiaoying impacts and a series of other situations that will cause fatal blows to living beings, including to humans today.
Land and oceans are different because most disasters are more destructive to land and less to oceans. It therefore follows that the characteristicsEvolutionary aspects of marine life are completely preserved. For example, by tracing a fish today, we can even know who its ancestors were in ancient times. Thanks to today's fish, we can learn what creatures looked like hundreds of millions of years ago.
But this is not possible on the ground. For example, if we want to restore dinosaurs, we need a large number of fossils as a basis, and after having discovered a large number of them. of fossils, we must proceed. To put them together, we also look for geological features from this period. This is a very, very difficult process, because even if the bodies of terrestrial organisms become fossils, some fossils will be damaged to varying degrees due to long-term geological changes on the earth. Therefore, you will find that the creatures on the surface of the earth are betterthan creatures on earth to retain their ancient characteristics.
However, even for creatures that live inside the ocean, they are unable to adapt to large-scale environmental changes, because once the he earth's environment will change, this will not only happen on land, but also in the ocean. There are species living inside the ocean. If the range of environmental changes is relatively broad, most marine species will become extinct because they cannot adapt to the environment.
The once-forgotten era of mass extinctionEarth has experienced five mass extinctions. The scale of this extinction covers the sea, land and air. It is so vast that only a few species have had the chance to do so. survive during this period, they will live with new species in the new era.
The giant panda, the alligator and the Chinese sturgeon thate we all know are known as “living fossils”. They are survivors of the previous era and coexist in this era. However, the luckiest species are living fossils. In the “ocean” they are inconspicuous and rare in number. At the same time, they are the best gift left to humanity from previous times.
The birthplace of marine life is also a good place to “hide”.The ocean is the origin of biological cells. Based on today's understanding of life on earth, we know that water is an important element. condition for the production of life. Water-carbon Builds the basic skeleton of living things.
Ocean sediments are rich in inorganic matter, which to a large extent provides the conditions necessary for the gestation of life, therefore it is the starting point of marine life.
With the continuous improvement of science and technology, creative'Hidden' ures in the depths of the ocean are constantly being discovered, even including prehistoric species, the most famous being the spearfish, caught by the South. African fishermen in 1938. Museum staff heard about this strange fish, recorded it, took photos and sent the photos to Professor Smith, a fish expert, who discovered that it was of a prehistoric creature, the spearfish, which had been thought to be extinct. I thought that the lancetail fish lived under the noses of humans for many years without being discovered.
Compared to the known prehistoric creatures on land, more unknown prehistoric creatures should be hidden in the boundless sea.
A dataset shows the size of the ocean. The ocean area is 361 million square kilometers, representing 70.8% of the earth. The land area is 149 millionof square kilometers. , occupying only29.2%of the area.
Why did the ocean become the “protective umbrella” of prehistoric creatures?The author believes that the depth of the ocean provides a greater protective cover. Fish living in shallow water areas are sensitive to environmental factors, while deep sea fish are less affected. are all bottom-dwelling fish and live in the deep sea. Perhaps this is why they escaped mass species extinction.
In addition to environmental factors, food acquisition is also a key factor. Giant pandas belong to the Ursidae family, and brown bears and polar bears eat meat! The giant panda has become an alternative to the bear family and is vegetarian. Going from meat to vegetarian, so it became a survivort.
The ocean is extremely rich in species and food sources are diverse. Basically, big fish eat small fish and small fish eat shrimp, layer by layer.
Although some creatures are in the era of mass extinction, they have managed to survive due to unique conditions (multiple factors).
It should be noted that environmental changes continue to change. Prehistoric creatures have undergone some changes, but their fertility appears to be limited. If you're not careful, they can become an endangered species. thing of the past again.
I remember the first bad news I received in 2020 was that the Yangtze River Spoonbill was extinct. They survived the mass extinction, but were defeated by the human era.
Overall, the ocean was once a refuge for prehistoric creatures, but it isnow become a rope that binds them.The color of life lies in the richness of species and the harmony between man and nature. Infinite requests have only one end.
Dong Qing once said a classic saying: when the gun goes off, there is no winner, which clearly explains the coexistence between humans and living beings.

Every time there is a mass extinction on earth, 95% of the creatures on earth are extinct. Shallow water areas of the sea are extinguished first, and deep sea creatures are unaffected. Land plants disappeared first, followed by large animals. Only small omnivores escaped mass extinction.
Marine organisms can survive as long as there is water and air. On earth, for example, if a large meteorite explodes or a volcano eruptsn, there may be no sun, no plants, and they may starve. death.
We all come from the ocean. Protect the ocean. Stop throwing away plastic products? Is it OK to discharge toxic wastewater? Nature gave the answer thanks to the Xunyi system. Cherish the ocean. Protect the sea. Act quickly.
