I believe many people know that the earth now has seven continents, which are separated by oceans. The most mysterious of the seven continents is the Antarctic continent. We all know the Antarctic continent now, but few people knew about it before mankind entered the technological age.
The earth has a history of 4.6 billion years. The ancient earth does not have seven plates like it does now, but has only one piece of land, which we call Pangu continent. Dashu 234 million years ago, geological movement caused the Pangea continent to continue to split. After millions of years of splitting activities, the current seven continents were finally formed.
Because the seven continents are separated by the ocean, different ecological environments are formed, and there is no support of transportation, there is basically no contact between people on different continents. Asians do not know the existence of the other six major sectors, nor do they know the existence of each other. Later, some courageous explorers began to go out and explore, so there were constant discoveries on other land.
The Antarctic continent is the last piece of land discovered by mankind. It is completely different from the other six plates. It is a world of ice and snow. The Antarctic continent was set as a forbidden area for humans in ancient times. It was more cruel than the desert, and the ultra-low temperature made people who walked into it almost dead.
The total area of the Antarctic continent is 13.9 million square kilometers, equivalent to the total area of China and the India-Pakistan subcontinent, ranking fifth among all continents in the world. The entire Antarctic continent is covered by a huge ice sheet, with an average elevation of 2,350 meters, which is the highest continent in the world.
It was not until mankind entered the age of science and technology that with the help of science and technology, mankind began to have a strong interest in Antarctica, and many scientific research stations were built there. Basically every medium and large country has its own scientific research station in Antarctica, and the once forbidden area for humans has also begun to be crowded.
Many people may have questions: Why are scientists all over the world actively researching and exploring Antarctica? Is there any secret there? As the most mysterious and complicated Antarctic continent among the seven major plates of the earth, it is normal for something mysterious and unknown to exist. After humans entered the age of science and technology, their understanding of land has basically been about the same, and the last thing left to understand is the Antarctic continent.
The original scientists explored Antarctica mainly to explore some unknown creatures and unknown things there. However, with the rapid development of human industry and the continuous increase of global temperature, more scientists are full of deep concerns about the melting of Antarctica’s ice and snow. You know that the entire Antarctica is a big block of ice, and the amount of water stored here is amazing.
Once Antarctica melts and a large amount of water is injected into the ocean, migration will cause the sea level to rise sharply, which will bring a huge crisis to the survival of the earth and mankind. Therefore, the main task of many Antarctic scientific research stations is to monitor the melting of ice and snow in Antarctica. Once a special situation is discovered, we must study and analyze it in time to see what it will bring to humans.
The melting of ice and snow in Antarctica has always been in a relatively normal state, but scientists discovered an unexpected situation through the latest observations of Antarctica. It turned out that large and small water holes appeared in the east of Antarctica. Perhaps for many tourists, these water holes appear in Antarctica, which is a very beautiful scenery. However, when scientists saw these water holes, they were not happy at all, instead they were full of deep worries.
What kind of warning does the appearance of these water holes give us? In fact, we all know that the appearance of water holes is actually the result of melting ice and snow. However, the normal melting of Antarctic ice and snow is from the outside to the inside, that is, when the temperature of Antarctica increases, the outside of the ice layer is melted first. This melting speed is relatively slow and can give humans more time to think and study.
But when these large and small water holes kept appearing, the situation changed completely. It tells us that the melting of glaciers in Antarctica has not only started from the outside to the inside, but has begun to develop from the outside to the outside, and even the speed of melting from the inside is faster than the speed of melting outside. This is not a good sign. If the Antarctic glaciers melt from the outside to the inside, then the entire Antarctic plate can still maintain a relatively stable state.
But now that the melting of glaciers is a combination of inside and outside, the stability of the Antarctic ice will become worse and worse, and the entire ice will continue to split and then drift into the ocean. The entire glacier is constantly torn apart. Once it enters the ocean, it means that the glacier will melt faster. This allows scientists to see the crisis of mankind. They must know that once the Antarctic glaciers are all melted, it means that all the Arctic glaciers will basically melt.
All glaciers in the Arctic and Antarctic melt, and the most conservative estimate will also raise the sea level by 50 meters. What is this concept? In fact, it is equivalent to another global flood on the earth, and most of the land will disappear. I believe many of my friends have heard about the prehistoric flood. A long time ago, there was a global flood on the earth, and the entire land of the earth was basically destroyed.
This prehistoric flood seems to many people to be a legend, but through a lot of research and exploration, scientists believe that the prehistoric flood may have actually occurred. More importantly, scientists have found many fossils of marine life at the foot of Mount Everest, which shows that the earth once was indeed full of water and has been submerged to the foot of Mount Everest.
So is the melting of Antarctic glaciers only a substantial rise in sea level for the earth and mankind? Of course not. If it is just this impact, then scientists will not be too worried. We must know that at the speed of human technological development, we can survive even if the earth does not have land in the future. Just build some maritime cities, which is not difficult for some technological civilizations.
Therefore, the massive disappearance of land in the future will have little impact on human beings with advanced technology. Scientists are really worried about the ancient bacteria and viruses that are frozen under the permafrost in the Arctic and Antarctic. I believe many friends know that in addition to ice and snow, the Antarctic and the Arctic also have permafrost. This is an ice-covered land that has been formed over thousands of years.
The permafrost layer can be said to be a natural biological laboratory. In addition to freezing many ancient creatures, it also contains ancient bacteria and viruses. Naturally, we don’t have to worry about ancient creatures. What we really worry about is bacteria and viruses. We need to know that in a sense, microorganisms are equivalent to a kind of immortal life. They seem weak, but in fact, their vitality is very tenacious.
Bacteria and viruses are afraid of high temperatures and can be completely wiped out in high temperature environments. But they are not afraid of low temperatures. If the temperature is too low, bacteria and viruses will fall asleep, and they can sleep for tens of thousands, hundreds of thousands of years, or even millions of years. The permafrost in Antarctica sleeps countless ancient bacteria and viruses. Once the glacier melts, these permafrost layers will continue to recover. Among them, the frozen ancient bacteria and viruses may continue to be under the adapted temperature. recovery.
If you want to ask what is the most threatening life to mankind in this world? I believe many people will answer that it is bacteria and viruses. That’s right, this kind of microorganisms that we can’t see with the naked eye are the greatest threat to humans. Any new type of virus will cause a lot of trouble to mankind. However, we still know more or less about the new type of virus that appears in modern times, and we can have defensive measures and solutions.
However, ancient bacteria and viruses may be completely different from modern viruses, and they may be microorganisms that we do not understand at all. Once they pose a huge threat to the survival of the earth and mankind, the trouble for mankind will be great, and it may bring devastating disasters to the earth’s ecology and mankind.
Therefore, when scientists saw the emergence of large and small water holes in Antarctica, they were full of deep worries. This is actually a warning from nature to humans, telling us that if we do not protect the environment and the ecology properly. If the ecology is allowed to continue to deteriorate, then mankind may usher in a huge disaster in the near future.
