The earth is the home where human beings have lived for millions of years. As human beings enter the era of science and technology, there are more and more cognitions about this home. With the help of science and technology, many secrets of the earth have been discovered by human beings, but there are still many blind areas for human exploration.
Let’s not talk about the mysterious oceans and the interior of the earth, let’s take the land where human beings live for example. There is still a place we don’t know much about. This place is the place of the earth’s pole race – Nanji. For Antarctica, I believe many people know that it is called the Seventh Continent, which is the last continent to be found on the earth.
The total area of the Antarctic continent is 13.9 million square kilometers, equivalent to the total area of China and India Pakistan subcontinent, ranking fifth in the world. The whole Antarctic continent is covered by a huge ice sheet with an average altitude of 2350 meters, which is the highest continent in the world.
For a planet, its polar regions are often the coldest places, so are the earth’s north and south poles. Compared with the Arctic, there are too many secrets in Antarctica for human beings to fully explore. Although Antarctica is a very cold area and used to be a forbidden area for human beings, it does not mean that it is a forbidden area for life.
There’s still life in Antarctica, like penguins, as we all know. In the past, scientists’ knowledge of Antarctic life was limited to the surface, never considering that there would be abundant life under the Antarctic ice. But later, with the rising global temperature and Antarctic temperature, ice and snow began to melt. At this time, some scenes under the Antarctic ice let us know.
Scientists have discovered a new life world 800 meters under the Antarctic ice, overturning human’s cognition of life. Because Antarctica is an extremely cold region of the earth, the life there is very little, and it is basically concentrated on the surface. Under the Antarctic ice, many people think that there will be no life, but the melting of ice and snow shows us a new life world.
Science love has discovered thousands of microorganisms 800 meters under the Antarctic ice, which is an extraordinary discovery. How does life survive in the Antarctic environment when there is no sunshine and it is very cold? The discovery of abundant life under the Antarctic ice also gives us a new understanding of the tenacity of life. At this time, some scientists thought of extraterrestrial life.
Water is a very common resource in the universe. Take the solar system for example, many moons of Jupiter and Saturn have water, and many asteroids on the edge of the solar system are covered with ice. Many celestial bodies far away from the sun have water resources, which exist in the form of ice on the surface.
If there are a large number of microorganisms under the Antarctic ice of the earth, then there is a high probability that there will be life under the cold extraterrestrial ice. This has an important guiding significance for human beings to explore extraterrestrial life. We should know that human beings have been searching for extraterrestrial life since they came out of the earth for more than half a century.
In the past, scientists often used the earth’s warm ecological environment as the reference standard to search for extraterrestrial life. They thought that life was unlikely to exist in some extremely cold environments. However, the discovery of a new life world in the south pole of the earth has changed our cognition. Perhaps life is a universal thing in the universe.
As long as there is water on the planet, whether it is liquid water or frozen water, there may be life. However, it is believed that intelligent life like human beings is also very rare in the universe, because the birth of life may not have too high requirements on the ecological environment, and even the extreme planetary environment may also produce simple microorganisms.
But if we want to gradually evolve from simple life to complex life, or even advanced intelligent life like human beings, the requirements for the ecological environment will be very high. Perhaps only a perfect ecological planet like the earth has the possibility of the birth of intelligent life.
The discovery of a new life world under the Antarctic ice is just the tip of the iceberg that has uncovered the mystery of Antarctica. If the temperature in Antarctica doesn’t rise and it’s as cold as it used to be, it’s hard for us to really explore Antarctica. Without the continuous melting of glaciers, we will not find the life world under the Antarctic ice.
Although it is a happy thing to discover a new life world 800 meters under the Antarctic ice, it is not happy for many people. We can explore the life world 800 meters below the Antarctic ice, and we can see how fast the Antarctic ice and snow are melting now. And this trend is intensifying with the rising global temperature.
I believe everyone knows that if the Antarctic glacier melts, it will have a great impact on the earth’s ecological environment. The first is the sharp rise of sea level, a large number of coastal cities will be drowned, and human beings will lose a lot of land living homes.
Secondly, the rising temperature in the north and South will make the permafrost recover continuously, and the ancient bacteria and viruses frozen in it may also wake up step by step. The impact of these ancient bacteria and viruses on the earth’s present ecosystem is still unknown. If they are very harmful to life on earth and human beings, we may control and eliminate them. I believe many friends can think of the final result.
Many scientists have predicted the scenario that will appear in the future due to the rise of global temperature. In fact, we can also imagine that in the future, the earth’s land will basically disappear and there will be oceans everywhere, which is very similar to the early days of the earth.
According to the archaeological research of current scientists, in the early life of the earth, the land area was far less than it is now. At that time, the ocean area of the earth was more extensive, which can be seen from the discovery of marine fossils at the foot of Mount Everest. It was only later that the ecological environment continued to change, and the land area increased. It was only then that 29% of the current land area came into being.
If the earth is covered by oceans again in the future, how will human beings survive? In fact, we need not worry about this. With the rapid development of human science and technology, we will build a large number of marine cities in the future. Even without land, we can live in marine cities. And once we become an interstellar civilization, we can go to other planets to live. We don’t have to worry about what human beings should do if the earth can’t survive one day.
