The earth is the home where human beings have lived for millions of years. For this home, we should have taken good care of it. However, with the development of science and technology, the emergence of a large number of industries, industrial waste gas, waste water and other pollution sources have begun to destroy the earth’s ecological environment.
One of the biggest industrial pollution is the emission of carbon dioxide and other greenhouse gases. The rising concentration of carbon dioxide in the earth’s atmosphere aggravates the greenhouse effect and makes the global temperature rising every year. I believe that in recent years, friends can clearly feel all kinds of natural disasters brought about by the rising global temperature.
2019 is the year of El Nino, which is the pronoun of extreme climate. The direct reason for this phenomenon is the rising global temperature. In the past month, I believe many friends have seen the extreme climate change brought about by El Nino. In many areas of southern China, the continuous heavy rain has led to floods, mud rock flows and other disasters. In addition, the earthquake with a magnitude of 6 occurred again in Sichuan not long ago, which is actually related to the extreme climate change.
The impact of rising global temperature is far more than that, and the continuous melting of glaciers in the north and south poles will lead to the continuous rise of sea level. These are all natural changes that you can see, but there is one change that many people ignore, that is, the recovery of ancient viruses.
We all know that the earth is a planet of life. Apart from asking what kind of life people are most afraid of, I believe many people will think of bacteria and viruses, especially viruses, which are absolutely the greatest threat to human life. The occurrence of disease itself is infected with viruses, which can directly threaten the safety of human life.
If you want to ask which kind of life is the most tenacious, I believe many friends will still think of viruses. Some viruses have a very long life span and strong adaptability to the environment. They can live in extreme environments. Since the birth of life on earth, the virus has existed. It can be said that the virus is one of the oldest life on earth.
In ancient times, there were many viruses, some of which did not die with time, but were frozen up. I believe many friends know that the earth has experienced several ice ages, and some ancient viruses were frozen when the ice age happened. Some people may say that these ancient viruses were already dead, after all, tens of thousands of years have passed.
However, in recent years, scientists have successfully recovered some of the ancient beautiful viruses by recovering the virus samples from the Arctic frozen soil. This shows that the survival ability of ancient viruses is far stronger than our imagination. Although they have been frozen for tens of thousands of years, they are still likely to recover once there are suitable temperatures and conditions.
With the rising global temperature, in recent decades, the Arctic ice has been melting, and the frozen soil has begun to slowly recover. Scientists have found several samples of the giant virus in the permafrost of the Arctic circle. With the acceleration of global warming, once the frozen soil thaws, it is possible that the trapped deadly virus will be awakened again. Will this be a serious crisis for human beings?
The viruses tens of thousands of years ago are different from the viruses we have now. One of the most obvious characteristics of ancient viruses is that they are large, and the number of genes they contain is much larger than that of the viruses we have now. For example, in 2015, scientists found a virus called mollivirus siberium in the Arctic circle. This is a viral giant that flourished 30000 years ago.
Mollivirus virus contains an amazing 1200 genes. The number of genes of our virus is generally single digits. For example, the genetic material of AICI virus, which makes people scared, has only nine genes. It can be seen that many of the ancient viruses are Big Macs. They have more genes and more complex structures. They are more dangerous individual lives than modern viruses.
Scientists worry that these giant viruses may come to life in the near future with the continuous melting of glaciers and the recovery of the ice layer. Once these giant ancient viruses recover, it is still unknown whether they will infect human beings. If they can infect human beings and make them sick, it may be a bit bad. We know a lot about these giant viruses Less, once infected, it can be life-threatening.
The discovery of permafrost giant ancient virus, let scientists have a further understanding of the virus. In the past, we always thought that viruses were very small things, but the ancient giant beauty was about 30 times larger than ordinary viruses, which was almost the same size as bacteria, and its internal gene sequence was more complex.
Generally, we don’t think that viruses are living, but these megaviruses seem to show some unique life characteristics, just like a living individual with metabolic function. Therefore, some researchers began to look forward to the revival of ancient viruses under the frozen soil. Perhaps these ancient thawing viruses can let us re evaluate and examine the characteristics of the virus.
Of course, it is still unknown what kind of impact these ancient ice covered giant viruses will bring to the earth and human beings after recovery in the future. We do not know whether these viruses can threaten the survival of human beings. If they are not, maybe we should not worry too much. If they can threaten human beings, maybe we need to make sure in advance Prepare and develop relevant vaccines just in case.
