The earth is a beautiful ecological planet. With a perfect ecosystem, life will be born naturally. In 4 billion years, the early simple life was born. After a long evolutionary evolution, there is now a world of life rich in species, and intelligent life human beings are also born.
Life has not been unsuccessful in the long evolution of the earth. In different periods, the earth has experienced mass extinction events. Each time, at least 80% of the species have become extinct. In addition to the mass extinction event, under the laws of survival of the fittest in nature, many creatures also face the threat of death at any time.
Most of these dead creatures have completely disappeared on the earth, while some have been preserved. Nature is a very magical environment. Although it is cruel and ruthless, it can preserve a part of history for a long time.
It is the natural preservation ability of nature that allows many ancient fossils to be buried under the ground. By studying these ancient fossils, humans can obtain more life history on the earth and learn more secrets of the evolution of life. Through these secrets, the rapid development of human science and technology is promoted.
In addition to paleontological fossils, there are two places on the earth that can better preserve paleontological corpses. These two places are the South Pole and the North Pole. The north and south poles are the two coldest regions of the earth. Through extremely low temperatures, the corpses of ancient creatures tens of thousands of years ago can be preserved more completely, and they have more research value than biological fossils.
Some preserved corpses of ancient creatures, and even we can get a part of living DNA samples from them. With these samples, it may be possible to replicate and clone ancient creatures through genetic technology, allowing them to reappear on the earth after tens of thousands of years.
However, due to the extremely low climate in the Arctic and Antarctic, these paleontological corpses were buried in the permafrost. In the past, it was difficult for scientists to obtain research samples. However, with the rapid development of human industry and the emission of large amounts of carbon dioxide and greenhouse gases, the temperature of the earth is also rising.
Global warming has caused many climate changes, and it has also affected climate changes in the Antarctic and Arctic. The temperature of the north and south poles is also rising, causing the permafrost to continue to melt. After the permafrost has melted, the frozen corpses of ancient creatures are also continuously exposed.
The north and south poles are huge natural treasure houses of paleontology on the earth. With the continuous warming of global temperature, the dead bodies of paleontology are constantly appearing. This year, scientists found a complete biological body in the frozen soil of Siberia for many years. Later, according to the test, the body was a horned lark, and they obtained the corresponding DNA in this body, which is useful for studying the earth. The changes of biological species on Earth and the last ice age on the earth are of great significance.
After DNA analysis, this horned lark came from 46,000 years ago. With a complete NDA sample, we can compare the current lark genome map to find out the connection between the two, which can confirm the evolution of the entire organism. Evolutionary process.
From a biological scientific point of view, the constant appearance of paleontological corpses in the North and South poles is indeed a good thing. I believe many paleontologists are also very happy about this. However, from the perspective of the earth’s ecological climate and human survival, this is not good news. It is necessary to know that the continuous appearance of the north and south and the corpses of ancient creatures indicates that the global warming is intensifying, and the climate change in the north and south poles is becoming more and more obvious.
Human industrial emissions are making the greenhouse effect more and more serious, and global warming is intensifying, which has led to the continuous rise of climate temperatures in the Antarctic and Arctic. The rising temperature makes the frozen soil layer continue to melt, so is the effect that the corpses of ancient creatures continue to appear before our eyes? Of course not. If it is just this effect, perhaps scientists will not feel the situation is serious.
What really worries scientists is a series of subsequent effects caused by the continuous melting of frozen soil. We must understand that the deepest part of the ancient permafrost in the north and south poles can reach 1,000 meters, and such deep permafrost is not formed at the same time, but is divided into many layers.
The deeper the area, the longer the age, and the longer the frozen life time. In addition to the large number of ancient biological corpses, the frozen soil also contains a large amount of methane and carbon dioxide gas. Both of these two gases are greenhouse gases, and both can cause the greenhouse effect. As the global temperature warms, the frozen soil layer continues to melt, and a large amount of carbon dioxide and methane will also be released.
In recent years, scientists in the Arctic have repeatedly detected scenes and data about the release of a large amount of methane and carbon dioxide after the permafrost has melted. Seeing this data, scientists are very worried, knowing that the current melting of frozen soil is only in the upper layer of the surface, and has not penetrated deeper into the area.
After the melting of frozen soil releases a large amount of greenhouse gases, it will once again intensify the greenhouse effect, thus forming a closed loop. This endless loop is difficult to control and change, and it can only end when all greenhouse gases are released. But at that time, the temperature of the earth will rise to a terrible level, and the north and south poles will no longer be cold at all, but will become a warm place.
These are not the most terrifying and worrying things for human beings. Scientists worry about one more, and that is the terrible ancient virus. I believe that many people are worried and fearful about the epidemic that started last year and has not yet ended. Microbes are the largest group of life on earth, and there are also a large number of microbes in the human body. They can get along with humans friendly.
However, many bacteria and viruses from the outside world are not so friendly. They often invade human bodies and make us sick. Some serious viruses can even kill us. However, no matter how the current virus on the earth evolves or mutates, we are still able to work out relevant countermeasures and develop vaccines.
But for ancient bacteria and viruses tens of thousands of years ago, they are completely different from our current viruses. Once they are released in large quantities from the frozen soil. It may threaten the entire earth’s ecology, and cause a fatal threat to various organisms and humans.
In 2003, scientists discovered an unprecedented deadly virus in Antarctica. No organisms have been shown to be immune to this virus. If this virus spreads, it may cause the loss of most lives like pneumonia.
There are a large number of ancient dead bodies in the frozen ground of the north and south poles, and the number of ancient bacteria and viruses in the ice is too large to estimate. As the frozen soil melts, some of them may wake up and multiply. . I believe that many friends have seen doomsday movies like Resident Evil. The doomsday scenes in the movies are caused by viruses. If ancient viruses are constantly released from the frozen soil, the doomsday scenes in the movie may not be staged in reality. .
The cause of all this is global warming, and global warming is closely related to human industrial greenhouse gas emissions. To solve these problems fundamentally, we can only rely on science and technology. Only our rapid development of science and technology, with clean energy such as controllable nuclear fusion, can completely replace the current chemical energy, so that the earth’s ecology can be improved step by step. .
In addition to researching new energy sources, we must also work hard to study genetic technology. Once a terrible virus breaks out in the future, only powerful genetic technology can save us. Science and technology can study all the obstacles on the road of human civilization. The premise is that we must have strong enough scientific and technological strength, and we are working hard in this direction.
