The earth has an excellent ecosystem. It is this excellent ecosystem that gave birth to primitive life on the earth 3.8 billion years ago, and the long evolutionary evolution of later life, and finally the birth of intelligent life human beings.
The entire earth’s ecosystem is composed of multiple parts. From the atmosphere in the sky, the climate change on the earth’s surface, and the changes in the earth’s interior, they are indispensable. If any one part has a problem, it will bring unpredictable consequences to the entire ecosystem.
Due to the rapid development of human industry, the earth’s atmosphere is also undergoing changes quietly. For example, the content of carbon dioxide in the atmosphere is constantly increasing, which has led to more and more serious greenhouse effects, and the temperature of the earth is also getting higher and higher. Global warming has become an urgent problem facing human beings, and it may bring a series of bad results to the earth’s ecosystem.
In the ecosystem structure on the earth’s surface, the north and south poles are an important part of maintaining this ecosystem. The four seasons of the earth are largely regulated by the north and south poles, so we also call the north and south poles the “thermometer for human survival.” “With this “thermometer”, the climate on the surface of the earth can maintain a good state, and can bring a superior environment for the survival of life.
However, with the continuous warming of the global temperature, the temperature of the north and south poles is also changing rapidly. I believe many of my friends will remember that last year there was a rare high temperature of 58 degrees Celsius in the Siberia region of the Arctic. Such a temperature appeared in an icy Arctic region. , It is beyond the expectation of scientists, and its appearance also indicates that climate change in the Arctic is intensifying and major changes are taking place.
It can indicate that the Arctic climate is undergoing major changes, and there is another phenomenon that continues to appear, that is, ancient creatures continue to emerge from the frozen permafrost. Many of my friends have also heard about the similarity. In recent years, scientists have discovered a lot of ancient biological remains in the Arctic.
According to scientific reports, in 2018, scientists found a 40,000-year-old remains of an ancient creature in Siberia. Scientists did not know what species the remains were. It looked like a dog or a wolf. By 2020, through research, scientists finally determined what species the wreck is. It is a wolf from ancient times.
According to the measurement data, the wolf is about 40 cm long and is completely preserved in permafrost. The thawing permafrost layer allows it to reappear. This is undoubtedly good news for paleontologists. By studying this area of ancient creature wolves and modern wolves, we can understand the evolution of this creature, which is of extremely high value.
In addition to this completely preserved wolf remains, scientists also discovered some other ancient creature remains in the area in 2015 and 2017, such as the 50,000-year-old ancient lion cub discovered in the past two years, and last year At the time, scientists also discovered the larks with a history of 46,000 years.
These ancient creatures were found in the Arctic Siberia. They slept in the permafrost for tens of thousands of years, and were finally released with the continuous warming of the climate. This is good news in the paleontology world and has epoch-making significance. However, from the perspective of the earth’s ecology, we feel the crisis. They are all warning to mankind: The Arctic climate is undergoing major changes, and the earth’s ecological deterioration is also at a rate. accelerate.
Through the continuous appearance of the remains of these ancient creatures, we can see that the ancient Arctic may be a relatively good ecosystem, otherwise there will not be so many creatures, and with the continuous changes of the Arctic climate, there may be in the future More ancient creatures continue to emerge from the permafrost.
The Arctic Circle is a complex system. The more complex it is, the greater its impact on the Earth’s ecosystem. If the Arctic ecosystem undergoes major changes, it will also affect the entire Earth’s ecosystem with unforeseen consequences, and the emergence of these biological remains is not what scientists are most worried about. What really worries scientists is the bacteria and viruses hidden in these ancient creatures. .
Apart from the terrible aspects of the virus, I believe everyone has experienced it in the past two years, and the vitality of the virus is very tenacious. In a sense, it is a kind of immortal life. They can sleep for more than tens of thousands of years without extinction. If the conditions are right, the virus can wake up from a deep sleep.
The Arctic climate has formed a permafrost layer, which not only freezes a large number of ancient organisms, but also freezes a large number of ancient bacteria and viruses. Without major changes in the climate, these bacteria and viruses will never wake up, but once the climate warms and the permafrost melts, the ancient viruses in the ice may wake up.
Ancient bacteria and viruses are very different from our current bacteria and viruses. We know very little about them. Once they enter the circle of life, it may be a huge disaster. In addition to the Arctic ice-covered a large number of distant bacteria and viruses, Antarctica also has permafrost, which is also ice-covered with ancient viruses.
Two years ago, scientific researchers in Antarctica discovered a deadly virus never seen before in the permafrost. At present, there is no animal on the earth that can be immune to this virus. American scientists have issued a warning that once the virus recovers and spreads, no creatures on the earth will survive.
In addition to the threats of ancient bacteria and viruses, there are also a large amount of carbon dioxide, methane and other greenhouse gases in the Arctic permafrost. Methane explosions have already appeared in 2020. This is not good news for the Earth’s ecosystem. Once these frozen greenhouse gases are released into the atmosphere in large quantities, they will intensify the greenhouse effect and increase the temperature of the earth.
In view of the above situation, we can see that the Arctic climate is indeed undergoing tremendous changes. In the future, such changes will become more and more serious, which will affect the entire earth’s ecosystem. The consequences are not just the earth’s greenhouse effect. Seriously, it may cause other unimaginable devastating disasters. Therefore, strengthening the protection of the earth’s ecological environment is imminent. If we don’t protect the environment properly, it is possible that Hawking’s apocalyptic predictions may actually become reality, and humans will lose their homes on earth at that time.
