We all know that the earth is a beautiful blue planet. The reason for this is that 71% of the earth’s surface is oceans and only 29% of the land area. If the ocean area and the land area are reversed and interchanged, the ocean becomes 29% and the land becomes 71%. Is it better for the ecology of the earth and the survival and development of mankind?
Many people may think that after the land area accounts for 71% of the global area, it is a huge welfare for human beings. At that time, we will have more living space, and the house will not be as valuable as it is now. Isn’t this a huge benefit? That’s right, if the area of the earth and the ocean are really reversed, the area of each country can be expanded by 2.4 times.
Will the expansion of the land area bring welfare and benefits to mankind? The real situation may not be as we wish. The interchange of the earth’s ocean area and land area will also have a subversive impact on the earth’s ecology. Such drastic changes will also have a great impact on the survival of human beings. So what impacts and changes will there be?
First, after the land area becomes 79%, the number of coastal countries will be greatly reduced, while the number of landlocked countries will be greatly increased. The total length of the global coastline will also become shorter. If the total amount of water in the ocean remains the same, after the area is greatly reduced, the depth of the ocean will also increase significantly. The current average depth of the sea tip is about 3,795 meters, and after the ocean area is reversed, the average depth will become 9194 meters. At that time, many ocean depths will exceed the current Mariana Trench, and the deepest ocean may reach more than 20,000 meters. . The increase in the depth of the ocean will make it more difficult for humans to explore the secrets of the ocean.
The second is the huge change in the earth’s climate. Since the ocean area now accounts for 71% of the world’s area, the earth’s atmosphere is very humid, and there is naturally a lot of water vapor in the atmosphere. In this case, there will be no less rainfall. Rainfall is very important to the entire planet’s ecology. It can keep the planet in a beautiful ecological environment.
More importantly, abundant rainfall can promote the growth of plants. Only when plants are richer can they produce more oxygen through photosynthesis, and the earth’s air will be fresh, and humans will be able to breathe fresh air with sufficient Of oxygen for humans to breathe. Moreover, human beings need food to survive, and these foods cannot be separated from crops, and the growth of agricultural crops cannot be separated from rainfall.
However, if the ocean area becomes 29%, the water vapor in the earth’s atmosphere will be greatly reduced. At that time, although the land area of the earth was 2.4 times larger than it is now, most of the inland areas will become arid and rainless desert areas. Without sufficient precipitation, plants cannot grow, and a large amount of land will continue to desert at that time. Desertified land will make the earth desolate, the natural environment will be very harsh, and the temperature of the earth will be higher.
Finally, there is the question of human survival. Some people may think that after the land area is expanded by 2.4 times, we will have cheaper houses to live in. But in fact, when that time comes, houses may be more expensive, because there will be fewer places for humans to survive. As we have said above, after the ocean area is greatly reduced, the rainfall will also be greatly reduced. Except for some rainfall in a few coastal areas, there will be very little rainfall in the inland areas.
Without the moisture of rain, plants cannot survive, and a large amount of land will become desertified. Although the earth’s land area accounted for 71% at this time, about 60% of it may be deserts, and there will be even fewer places for humans to live and survive.
In addition to the problem of housing, the survival of human beings will also be more difficult. The reason is that the desertification of food crops will also be greatly reduced due to drought and less rainfall. The sharp reduction in food will make more people hungry. At that time, even though mankind has entered the age of technology, the biggest survival problem may be to eat a full stomach.
Some people may say, after the ocean area is exchanged with the land area, there is no benefit for the earth and human beings at all? Of course not. After the land area accounts for 79%, one of the biggest benefits is that the earth will have more and more abundant resources. We must know that after human beings entered the era of science and technology, their demand for resources is very large. Without the support of abundant resources, science and technology cannot develop rapidly, and mankind has no hope of becoming a stronger interstellar civilization.
With the earth’s current terrestrial resources, it is possible that they will be exhausted after a hundred years of use. If human beings have not yet become a preliminary interstellar civilization and have no ability to enter the exploitation of space resources, then the pace of human science and technology development will stop, and human civilization will also stop. Will be trapped on earth forever, most likely the end of the entire civilization.
But if the land area of the earth is expanded by 2.4 times, then the resources will at least double. At that time, there will be enough resources to support the development of human science and technology for another 200 years or so. As long as there is sufficient time, at the speed of human technological development, there will be no problem in becoming a preliminary interstellar civilization. As long as human beings become an interstellar civilization, they will completely get rid of the shackles of the earth. At that time, human civilization will also usher in new development opportunities.
Once human beings become a powerful interstellar civilization, powerful scientific and technological forces will continue to change the various environmental and survival problems caused by the large land area. For example, at that time we were fully capable of changing the climate and allowing inland areas to be able to With sufficient rainfall, a large number of plants will live, and the desert area will disappear.
Changes in technological power will turn a lot of land from deserts into oasis, the living space of mankind will become larger and larger, and the ecology of the earth will become better and better. It can be seen that after the ocean area and the land area are reversed and interchanged, it may not be a good thing. It may be more difficult for humans to survive in the early days. However, with the rapid development of science and technology, the future will get better and better. Whether the current ratio of sea to land is better or the ratio after the exchange is better, different people will have different opinions. What do you think?
