The Sea Level Drops by Four Thousand Meters

Without the large amount of water in the ocean to absorb the heat of the sun and regulate the temperature of the earth, the high temperature would be at least above 50 degrees during the day and below freezing at night, resulting in drought and waterlessness. Not to mention various other problems, such as surface purgatory and mass extinction of organisms. This is an unlivable environment... It mutated overnight, and there was no time to react. If it slowly disappears, humans can still have some time to react and establish ecological bases. Such unexpected emergencies will directly lead to total extinction.

This is not true. The ocean has dropped so much. First, a large area of ​​algae, the main producer of oxygen, will die, and then the oxygen content will drop. Everyone, including large and medium-sized animals, will suffer from "altitude sickness," which is a lack of oxygen, and then a large area will die. Secondly, most of the land will become deserts, with serious water shortages. Then, the temperature of the earth will rise due to lack of water, and the current plains may become 70 or 80 degrees Celsius. The atmosphere will also shrink due to lack of water (water is also part of the earth's mass, and the magnetic field will become weaker due to lack of water), as well as most other problems. Anyway, large mammals like humans cannot adapt to the earth. The doomsday you mentioned will not exist, and this species will only slowly become extinct.

If the sea level drops by 4,000 meters, can the earth still be inhabited? Water is the source of life. We don't just say it casually. Algae in the water are the main provider of oxygen for the earth. The average depth of the ocean is 3,700 meters. A drop of 4,000 meters means that the vast majority of the ocean is gone. The Earth's water cycle system collapsed. The oxygen manufacturing factory is gone. First, carbon dioxide rises sharply and the greenhouse effect is strong, causing mass extinction of living things and plants. People don't want to leave the earth, which is no longer a livable planet, to find a new home, but they also want to rebuild their home on the earth. Isn't this a foolish dream?

More than 200 million years ago, the earth had a minor extinction event of regression. The earth dropped by about 100 meters, and large species were basically gone. If you are 4000 meters away, then the earth will have to wait for the next Triassic or Ordovician radiation?

Even basic common sense is gone. Without algae to produce oxygen, the plants on land alone are of no use. They will die from lack of oxygen.

It's the end of the world if you drop 100 meters, but it's 4,000 meters, which is much worse than Resident Evil

A fantasy novel. The first dozens of chapters are very exciting, but after these imaginative plots, the author's writing power has obviously declined, and he can't think of the subsequent plots. He can only follow the previous routines and follow the fantasy of defeating monsters and upgrading.

At the beginning, I thought it was a survival game, but in the end, it was about fighting monsters and upgrading. After all the hard work of leading the team to collect food and drink, it ended up in vain. I sacrificed all my teammates and wandered alone? There is nothing to look forward to next. It's just about fighting monsters and humans with malicious intentions on the way home.

The sea level dropped by 4000m.
