I! Pretending to Be Reborn, Director of Doomsday Hoax

But that's not worrying at all,

Because viruses already occupy an important part of the ecosystem:

By specifically killing specific microorganisms, viruses can effectively control the population size of specific microorganisms, release nutrients from microorganisms, and maintain the stability of the entire ecosystem.This specificity for a specific host means that most viruses in nature do not infect humans, and can even be used to help humans eliminate specific microorganisms that cause infection.

As early as the beginning of the [-]th century, some pioneers injected specific phages into the human body to treat bacillary dysentery and achieved success.

In the contemporary era of increasing abuse of antibiotics and growing bacterial resistance, phage therapy may be able to guide humans to a new way to treat bacterial infections.

From this point of view, more and more new viruses have been identified from nature, which are not only harmless to the human body with a high probability, but also have potential scientific and medical value, so they can be used by humans!therefore,

Need to worry about an ancient virus beneath the ice?

Need to be afraid of some ancient microbial resurrection inside?

This is simply nonsense!

Sha Weizhao wished that every time he drilled into the ice, he would find a pile of microorganisms!

A young researcher laughed, "I also saw today that people on the Internet are worried that ancient microbes and viruses will affect humans. If these things, which have been behind for millions of years, can still bring us extinction Disaster, this is the biggest satire on the theory of evolution!"

A colleague next to him nodded and said: "Humans are very likely to have coexisted with these bacteria and viruses. Moreover, the immune system of modern humans has evolved. Ancient viruses have not mutated for so many years, and they may not be able to adapt to the environment."

Sha Weizhao was noncommittal about these discussions.

dong dong dong.

The drill pipe for drilling the ice layer finally reached the point, everyone cheered up and took the last drill pipe out of the ice layer.

People look at ice cores being pulled up by machines.

This is the core taken from the inside of the glacier, which is deposited after the perennial snow does not melt, and has a significant difference in bedding structure, just like the annual rings of trees.

This thing has a very important meaning.

In the field of ecology, especially in the research of Arctic and Antarctic ice sheets and ice sheet ecosystems,

Compared with historical records, tree rings, lake sediments, coral sediments, loess, deep-sea cores, pollen, paleosols, and sedimentary rocks, which can extract information about past climate and environmental changes,

The ice core has the characteristics of strong fidelity, large amount of information, high resolution and long time scale (ajdf), which can be called "a wordless environmental password archive"!

Ice core research drills ice samples from glaciers to crack the environmental code of ice cores, detect past climate and environmental changes, monitor modern climate and environmental changes, and predict future climate and environmental changes.

Specifically,

The ratio of hydrogen and oxygen isotopes in ice cores is an index to measure the temperature.

Ice core net accumulation is an indicator of precipitation.

The gas composition and content of bubbles in ice cores can reveal the evolution history of atmospheric composition.

Cosmic isotopes can provide evidence of changes in the intensity of cosmic rays, solar activity, and changes in the strength of the Earth's magnetic field.

Changes in particle content and various chemical components can provide information on atmospheric aerosols, desert evolution, vegetation succession, biological activities, atmospheric circulation strength, and volcanic activity in different periods.

In addition, ice cores also record the impact of human activities on the climate environment and various information.

"Take it back for analysis. This ice core is the most complete and valuable sample we have obtained so far. Perhaps it can provide some evidence for our research on why the sun went out..." Sha Weizhao said, with his hands behind his back , ready to leave.

At this moment, his student let out an exclamation!

"Teacher Sha, look, what is this!!"

Sha Weizhao froze, stopped, turned his head, and looked at a broken ice core in his student's hand.

On the snow-white broken ice, there is a black thread-like creature slowly wriggling...

At this moment, Sha Weizhao was stunned.

Under the extremely cold ice core, are there any creatures that are still alive? !

Dragon Kingdom time.

Five o'clock in the afternoon.

The meeting on "Extreme Weather Changes and Paleontological Recovery Before Xiaobingliu Time" meeting was officially held.

Many people came from all over the country by special plane, and a small number of people came from the scientific research station in the Arctic.

As for the Antarctic side, the journey is far away, and there are no ecology experts there.

In this meeting, in addition to veteran ice sheet ecosystem experts such as Sha Weizhao, there are also paleontologists and archaeologists in the textbooks of Longguo E.

What surprised Xu Qiu was that there was an old face here, Cha Hongshuo!

Cha Hongshuo is a giant in the forest ecosystem. However, this big man also has a deep research on paleoecology, which is the main reason why he also participated in the conference this time.

After a short wait, Xu Qiu entered the meeting room.

At this moment, everyone in the Great Hall of Thousands stood up, looking at Xu Qiu on the stage with burning eyes.

"Director Xu!"

"very young!"

"He's even more handsome than on TV!"

People did not expect that this person who holds the highest authority of the Dragon Kingdom Dangerous Information Bureau and single-handedly leads the entire country's doomsday construction is much younger than he looks on TV. "Seniors, sir."

Xu Qiu's eyes wandered around the venue, sharp and majestic.

He saluted an ancient gift and said without talking nonsense, "Our meeting, speaking of it, has only one purpose! Paleontological recovery!"

boom!

Paleontology Revival!

These five words cheered everyone present, and many people even showed expressions of surprise.

Most of the people present are old experts who have been dealing with paleontology for many years.

What they see most are the fossils of various ancient organisms, which are nothing more than a complete corpse.

Now, there are ancient creatures that are about to be revived?

"Director Xu, the recovery of paleontology...is related to the Little Ice Age?" asked a biological extinction researcher.

Xu Qiu nodded, and said: "Indeed, this recovery of ancient organisms may also be the first event in which human beings have experienced the recovery of ancient organisms, and it happened at the same time as the Little Ice Age."

"Director Xu, what is this ancient creature?" This question is what everyone cares about the most!

Xu Qiu shook his head, and said in a deep voice, "To be honest, I don't have an answer to this question, and that's why I'm looking for seniors to discuss countermeasures."

Sha Weizhao, who was sitting in the front row, remained silent.

Xu Qiu asked: "Everyone, I would like to ask the first point, if the ancient organisms recover, what species can pose a threat to human beings!"

After a brief discussion, the paleontologist, dean of the Department of Paleontology and Archaeology at Qinghua University, and an expert in paleontology and archaeology in Longguo stood up and said:

"Director Xu, as far as current human technology is concerned, any large prehistoric animal may not be able to pose too much threat to human beings.

"Take the former world overlord dinosaurs as an example. Even without human technology, such giant creatures would not be able to adapt to the modern environment.

"At most, dinosaurs can only pose a threat to a very small number of people in a small area. Without human intervention, within a few days, dinosaurs will die because they do not adapt to the modern environment and become extinct again." The paleontologist said on his face Has a relaxed expression.

In fact, these so-called overlords are only relative to that era.

In terms of combat effectiveness, the so-called prehistoric creatures are simply not qualified to compete with today's humans.

He went on to say: "The only threat is probably some microorganisms, ancient viruses and other species, and only these things can affect the human ecology.

"It's just that there are millions of viruses in nature, but humans have only discovered a few thousand so far, so what if we recover a few, hundreds of them?

"What's more, the virus is not getting stronger and stronger. It is a highly specific thing. The ancient virus has a high probability that it will not be able to infect our modern new generation organisms!"

Cha Hongshuo thought for a long time and asked:

"Is there such a possibility?

I also know that viruses are host dependent.

If a virus becomes too virulent and kills all hosts, the virus becomes extinct.

For example, smallpox in history had a high mortality rate, but it was not finally wiped out until a vaccine was developed.

So, is there a possibility that there is a certain virus that killed all the human hosts at that time, leading to the extinction of this virus...

But in some places where viruses can be preserved, such as the North and South Poles, a host killed by it happened to be frozen, leaving the only virus.

Now that the glaciers are melting, it comes out and spreads causing mass death? "

The paleontology expert shook his head and said, "This is too difficult, and the probability is too low.

"Assuming your statement exists, you want this kind of virus that can destroy human beings to appear, and it happens that it can match the biological binding site of human beings today, and it is guaranteed to have the same toxic effect on human beings today... "This probability, It is so small that you can find a random pile of stones in the river, and each piece of this pile of stones has been washed out by the river water with the words "Ordered by Heaven, Longevity and Prosperity".

"The probability is so small that it can be equated to impossible!"

Cha Hongshuo does not agree with this point of view.

He frowned and said: "Although the sun is about to go out, the world is still warming abnormally.

According to the results given by the Meteorological Bureau, the highest temperature in some areas of Longguo this year reached [-] degrees Celsius, and the time came to late August, and the temperature continued to rise.

There is no downward trend at all because of the Little Ice Age.

Many people present are meteorological experts. Therefore, everyone is aware of the crisis due to the abnormally high temperature this year.

The permafrost is gradually melting!

And the ancient viruses and bacteria sleeping in it may be released as the permafrost thaws and come back to life.

When ancient deadly bacteria and viruses that have survived for thousands of years or that humans have never encountered suddenly appear in front of humans, won't humans suffer a devastating blow? "

Cha Hongshuo's eyes were full of worry, recalling some things related to this before, and said:

"Four years ago, an anthrax outbreak returned to the tundra near the Arctic Circle, the Yamal Peninsula, killing a 12-year-old boy.

At least twenty people had to be hospitalized for anthrax.

Permafrost is an ideal dormant place for bacteria to remain active for a long period of time, perhaps as long as 1 million years.

This means that ... melting ice and soil may open the Pandora's box of disease, which poses a serious threat to human survival.

Permafrost is the habitat of microorganisms and viruses. It is cold and oxygen-free, and there is no light. Pathogen viruses that can cause human or animal infections may remain in the original permafrost. This includes the past caused global epidemics. some virus.

What is even more frightening is that there may still be some undiscovered viruses lurking under the permafrost.

In the permafrost, there are human and animal remains buried for centuries, so it is not difficult to imagine other infectious materials being released from it.
