Any planet has two poles, whether it is Venus or Mars, there are two poles. The earth naturally has two poles, and the polar regions are often the coldest places on a planet. Venus is a purgatory planet with a surface temperature of 460 degrees Celsius, but the temperature at the poles is not high.
The average temperature of the earth is about 15 degrees Celsius, but the temperature in the poles is much lower than this average. It is precisely because the temperature at the poles is very low that there is a world of ice and snow, covered by snow and ice all year round. It is the most extreme place on the earth’s surface environment, especially the Antarctic, and it is a forbidden area for mankind.
In the history of human civilization from ancient times to the present, I do not know how many people have stayed there forever because of exploring Antarctica. Its cruelty is far more terrifying than exploring the boundless desert. The existence of Antarctica is very important to the entire ecosystem of the earth, because its cold properties can adjust the temperature of the earth’s environment, keeping the earth’s temperature in a suitable range, so that life can better survive.
However, as mankind enters the age of science and technology and the rapid development of a large number of industries, the carbon dioxide greenhouse gas produced has brought tremendous changes to Antarctica. We all know that carbon dioxide is a very powerful greenhouse gas. The reason why the temperature of Venus is very high is because 95% of the atmosphere in the atmosphere is carbon dioxide. Due to the large amount of carbon dioxide emitted by industry, the concentration of the earth’s atmosphere is also increasing, which has caused the greenhouse effect to become more and more serious, and the temperature of the earth is also increasing.
The ever-increasing ambient temperature not only makes people unbearably hot, but also brings some very bad major effects to Antarctica. In recent years, scientists have continuously discovered some fractured ice layers and some deep pits in Antarctica. One of the mysterious giant pits has attracted the attention of scientists. The scientist sighed after studying: This was originally something that shouldn’t exist.
Something that shouldn’t have appeared in Antarctica has now appeared, making scientists very worried about it. So what is going on with this huge crater? After detection and observation, scientists said that the area of the giant crater can reach 2/3 of the total area of Manhattan, and it is still expanding. This “giant hole” is actually a natural phenomenon. It is called “ice lake” by scientists, but scientists have never discovered such a large “ice lake” in history, and the expansion of this ice lake The speed is amazing.
The appearance of ice lakes in Antarctica is actually a normal natural phenomenon. Even in Antarctica, which was very cold in the past, some ice lakes will also appear, mainly due to strong winds. The strong wind blows away the thin ice layer, and the warmer sea water under the ice layer rushes up, preventing this area from strong ice and forming a small ice lake.
Therefore, Antarctica has not been a world of ice and snow since ancient times. There are still some small lakes in it. They are small ice lakes that have appeared due to strong winds. The appearance of these small glacial lakes does not have much impact on the ecological environment of the entire Antarctic, but the giant glacial lake discovered by scientists in Antarctica is different. It is not caused by strong winds.
Scientists believe that the emergence of this huge “hole” has a lot to do with ocean currents and monsoons. Perhaps it is because of various coincidences that this natural phenomenon that shouldn’t have appeared. The emergence of this huge hole also warns humans that Antarctica is undergoing huge unknown changes, and this change is caused by the greenhouse effect, which will have an unimaginable impact on the entire planet’s ecological environment, and it will also affect humans. Survival poses a huge threat.
Many friends know that the rising temperature of Antarctica will bring about continuous melting of ice and snow. In fact, anyone who has traveled to Antarctica in recent years will be able to discover the fact that the environment of Antarctica is getting warmer and warmer, and Antarctica is getting warmer and warmer. Green, a lot of green plants began to appear. Perhaps for friends who like to travel, Antarctica can turn green and warming is a very happy thing.
But for the ecology of the earth and the destiny of all mankind, this is a very bad thing. Related professionals have conducted data surveys, and if the ice in Antarctica is completely melted, the sea level of the earth will rise by about 70 meters. This is a very terrifying data, because let alone a rise of about 70 meters, every rise of one meter will pose a great survival threat to coastal cities. If you rise by 70 meters, all coastal cities on the earth will be submerged under the sea. .
After losing a lot of land, how can human beings survive? At that time, human beings may only have two choices. One is to move to the outer planet to reduce the pressure on the planet to survive, and the other is to build a sea city. Originally, the land area only accounts for 29% of the world’s area, and one-third of it is still desert. Such a small land for the survival of 7.5 billion people around the world would have been choking, but once the sea level rises by about 70 meters, less than 10% of the earth’s land may remain.
At that time, where the 7.5 billion people should go, apart from moving to the outer planet, we can only survive by building a sea city. Of course, whether it is moving to an outer planet or building a sea city, it is impossible for humans to do with current technology.
Therefore, human beings are actually racing against time. The trend of the deterioration of the earth’s ecology may hardly be truly changed. Even if we make some efforts, we can only slow down the deterioration of the ecology. The ultimate earth’s ecological environment may be true. As Hawking predicted, it will become an environment that cannot adapt to human existence.
Of course, it will take a long time for the earth’s ecological environment to completely deteriorate to the point where it cannot adapt to human survival, but the speed of melting ice and snow in Antarctica is now urgent. We may really want to live on the sea in the future, so we need to build a lot of sea cities, and this requires more technology. Therefore, human science and technology must accelerate the development speed. Before the Antarctic ice and snow completely melt and a large amount of land is submerged, we can have maritime city construction technology.
Back then, from a long-term perspective, the future of mankind was to walk out of the earth, to the starry sky, and achieve interstellar colonization, spreading its footsteps to all corners of the galaxy and even all corners of the universe. As long as human beings become an interstellar civilization, we can completely get rid of the shackles of the earth and the shackles of a galaxy. At that time, the entire universe is our home.
