What 'prehistoric creatures' were dug out as the Arctic permafrost melted? Why do humans get nervous?
The reason why the world is beautiful is that organisms are rich and colorful. Countless species of organisms constitute a very large biosphere. Animals, plants and microorganisms live happily on the earth. However, not all creatures exist all the time. Many creatures on the earth are extinct due to various reasons. Many scientists even say that the extinction of some creatures is inseparable from frequent human activities.
The earth has experienced 5 mass extinctions since its birth. This seems to be a fixed time node. Every time it reaches a certain level, the earth will enter the "clearing" mode, and the creatures that are no longer suitable for living in the earth's environment will be eliminated. In addition, in addition to experiencing a mass extinction, the earth will also experience a biological explosion. The two are interlinked like a closed loop that continues to circulate. The environment of the earth is not as good as before. Human beings have developed for so many years, and the damage caused to the environment is unimaginable.
And what I’m talking to you today is, is the permafrost melting? Prehistoric creatures reappeared 57,000 years ago, scientists: humans should be vigilant. In recent years, global warming has become more and more serious, and global warming has caused the rapid melting of polar glaciers, and a large number of penguins and polar bears have lost their original habitats. Until now, there is still no good solution. Under the thick ice layers of the Antarctic Circle and the Arctic Circle, there are very old frozen soils, but these frozen soils are very dangerous, because ancient biological corpses or germs may be buried under the frozen soils.
Recently, a paper was published in the journal Current Biology, and scientists discovered a 57,000-year-old corpse of a prehistoric creature in the Arctic permafrost. This is the "mummy" of a wolf cub, and it is also the most complete wolf mummy known so far. It can be said that due to the protection of the permafrost layer, it was extremely well protected when it was discovered, and even the contents of its stomach were checked out. So how was it discovered? In fact, it was the melting of the permafrost that led to the discovery of the wolf cub body. It has to be said that there are too many unknowns contained in the frozen soil under the polar glaciers.
The presence of polar permafrost plays an important role in the global climate. These permafrost contain a large amount of carbon deposits and long-dead plants that cannot decompose or rot. As the permafrost melts, a large amount of methane and carbon dioxide will be released, which will lead to a more and more pronounced greenhouse effect. Accelerating the thawing of permafrost can be described as falling into a vicious circle.
In this regard, scientists are very worried, saying: Human beings should be vigilant! As the permafrost melts, these viruses may break free and return to the earth. If humans continue to destroy the environment and ecology, we have no idea what will happen in the future. If that day comes, it will be too late for humans to do anything.
Melting permafrost? Prehistoric creatures reappeared 57,000 years ago, scientists: humans should be vigilant. It is time for human beings to wake up. It is imminent to deal with the problem of global warming. Only by maintaining our living environment can human beings live a better life.
