In 1820, under the leadership of bellinghausen and Lazarev, an expedition discovered Antarctica, the last unknown continent in the world. Since its discovery, “everything” here has not changed.
The Antarctic continent is the last place discovered by human beings. It is covered with ice and snow all the year round, and the temperature is very low. It is the coldest place on earth. Due to the cold of Antarctica, it has always been a forbidden area for human beings. Even explorers dare not go deep into Antarctica, so they know very little about Antarctica.
With the development of human science and technology, with more powerful science and technology, countries around the world have begun to explore Antarctica. At present, there are many observation stations in Antarctica. Through continuous investigation and research, we have more knowledge of Antarctica.
Antarctica is the largest reservoir of fresh water on earth. However, it exists in the form of ice with an average thickness of about 1.6 km. About 70% of the earth’s fresh water resources are accumulated here, rather than in terrestrial lakes and rivers. What would it look like under the thick Antarctic ice sheet?
Through satellite observation and simulation, scientists speculate that under the Antarctic ice is another shocking scene: Plains, valleys and peaks. Of course, if you want to really understand the situation under the Antarctic ice, you still need to go deep into it. However, due to the harsh environment in Antarctica, it is not easy to drill in the Antarctic ice, so scientists’ Antarctic exploration research has not made much progress.
However, with the rising global temperature, the temperature in Antarctica has also improved significantly in recent years. A lot of ice and snow begin to melt, and some things under the ice have begun to appear. However, after the melting of ice and snow, something that scientists are worried about appears. In fact, through years of research and exploration, scientists have made some guesses about things under the Antarctic ice, such as a large number of volcanoes, a large number of ancient bacteria and viruses.
Antarctica is the most mysterious continent on the earth, and the earth is a rocky planet, naturally without volcanoes. According to many years of exploration and research by scientists, it is speculated that there are many volcanoes in Antarctica, most of which are hidden under a layer of ice. According to various sources, the number of volcanoes in Antarctica ranges from 40 to 90. Some of these volcanoes are still relatively frequent, such as the erebes volcano.
With the continuous rise of Antarctic temperature in recent years, a large number of glaciers continue to melt. At this time, a large number of volcanoes hidden under the ice sheet begin to surface. At present, nearly 50 volcanoes have appeared. With the rapid melting of glaciers, there will be volcanoes in the future. The rise of these volcanoes is a big threat to the whole earth’s ecology.
In the past tens of millions of years, these subglacial volcanoes have been covered with ice and snow, but now the global temperature is rising, and they begin to surface continuously. Will there be violent geological activities in the future that will cause these volcanoes to erupt? This possibility is not absent. The melting of Antarctic glaciers has a great impact on Antarctic geology.
In addition to the appearance of these volcanoes, the melting of Antarctic glaciers has also slowly revived the frozen permafrost. You should know that there is a huge area of ancient permafrost in the north and south poles, which has been frozen for tens of millions of years. In the long years, countless organisms, bacteria and viruses have been frozen in the permafrost.
It can be said that the ancient frozen soil layer in the north and south poles is the largest biological experiment freezer on the earth, in which various biological samples from tens of millions of years ago to the present are frozen. If the frozen soil layer recovers, the animals will not be able to revive, but the bacteria and viruses in the frozen soil are hard to say. Scientists once collected some frozen ancient bacteria and viruses here, and recovered them in some laboratories.
It can be seen that the ecological capacity of bacteria and viruses is very strong. Even if they have been frozen for tens of thousands of years, as long as the environment is suitable, they are likely to recover. If these frozen bacteria, viruses, ancient bacteria and viruses continue to revive and reappear in the world, it may have a great impact on the earth’s ecology and human survival.
I believe many people know that bacteria and viruses pose a great threat to human beings. These invisible viruses are the most terrible. It is often difficult for people to prevent them, and their transmission ability is very strong. What’s more, we know very little about ancient bacteria and viruses. Once they are harmful, infection may spread very quickly, and it is difficult to find relevant vaccines and prevention in a short time.
Maybe many people’s harm to the Antarctic ice and snow melting still lies in the fact that it causes the sea level to rise sharply. In fact, the rising sea level caused by the Antarctic ice and snow melting is only a very small harm. With the development of human science and technology, it is not difficult to solve this problem. At that time, we could build marine cities to meet the living needs of human beings.
The real threat to the earth and mankind is the recovery of rising volcanoes and permafrost, especially the latter. Once out of control, it may be the end of the earth. So now, scientists are speeding up the exploration of Antarctica, especially the study of ancient bacteria and viruses in the permafrost.
Of course, the plan can’t keep up with the changes. We can’t predict what will happen in Antarctica in the future. However, one thing is basically certain, that is, it is difficult to effectively control the melting of Antarctic ice and snow. The main reason is that the rising trend of the earth’s temperature is difficult to change.
Although in recent years, the world has been continuously strengthening environmental protection, but little has been achieved, and it can even be said that it has not reduced carbon dioxide emissions. In fact, according to a research report by scientists in 2019, carbon dioxide in the atmosphere has been continuously reaching new highs and has not decreased. This shows that the earth’s ecological environment is still accelerating deterioration.
In fact, this situation has long been expected by scientists. The reason is very simple. Industrial production is the root cause of the deterioration of the earth’s ecology. However, it is impossible for us to give up industrial development and stop industry to improve the earth’s ecological environment. Once the industry stops, the development of human science and technology will also stop, and the impact and harm may be greater. Therefore, industrial development can not be weakened, but will accelerate in the future. Only in this way can science and technology develop faster.
With the rapid development of industry, carbon dioxide and other emissions are also increasing, which is a difficult problem. Unless human beings really master the controllable nuclear fusion technology, they can replace the traditional industrial mode and let human beings completely get rid of the shackles of traditional energy. However, it may take at least half a century for us to fully master the controllable nuclear fusion technology. During this period, no one can tell the extent to which the earth’s ecological environment will deteriorate.
