In 1993, Steven Spielberg's "Jurassic Park" won the Best Visual Effects Award at the Academy Awards, and the vivid and realistic dinosaurs in the film became a shocking scene of countless people's childhood memories, and this film also set off a global boom in dinosaur IP.
In "Jurassic Park", scientists extracted the genetic information of dinosaurs from the blood of ancient mosquitoes, and successfully bred dinosaurs, and these huge ancient creatures appeared in front of people. Of course, this is just a science fiction story, and we can really see some strange prehistoric creatures in real life, but in the form of fossils.
As global warming continues to intensify, the permafrost in the Arctic region begins to melt at an accelerated rate, which slowly exposes some deeply hidden prehistoric remains, which are very well preserved in natural ice coffins and have high research value, but at the same time, researchers say that this phenomenon is not a good thing, and what is the reason for this?
<h1 class="pgc-h-arrow-right" data-track="5" > prehistoric organisms in permafrost</h1>
Siberia is very rich in permafrost resources, and it is also in the thawed permafrost layer here that scientists have found the remains of many prehistoric creatures.
In 2007, a Russian breeder accidentally found the remains of a mammoth in the frozen soil north of the polar circle, and according to paleontologists' estimates, this huge prehistoric creature lived about 40,000 years ago, probably encountered a disaster such as gravel, because it could not escape suffocation and died, and the mammoth became frozen in extremely low temperature climates, and the mammoth was wrapped up and became a living specimen.
Three years later, another fossil of a prehistoric organism was found in the northern part of West Siberia, this time a bison whose biological structure was far from today's cattle, attracting great attention from the paleontological community.
In 2015, a hunter found the carcass of a long-haired rhino emerging from the permafrost in the Territory of the Sakha Republic, a species that, according to the researchers' inference, was extremely close to the skeletal structure of the Sumatran rhinoceros, which lived about 10,000 years ago.
In addition, new prehistoric creatures are constantly emerging in Siberia, such as cave kiln lions, mummified dogs and so on.

The fact that the permafrost is able to preserve some large animals in astonishing integrity has excited many paleontologists who can't wait to see more unknown species, but science is not designed to satisfy curiosity, and the remains of these prehistoric creatures certainly have high species value, but they also bring very dangerous things.
The discovery of prehistoric viruses has been accompanied by the excavation of prehistoric remains, and unlike those creatures that have completely died, these viruses are still alive, and the disasters they may bring to humans after they reappear from the permafrost are unforeseeable. So for these biological remains from 10,000 years ago, the researchers say this is not good news.
In 2003, a soft-bodied virus was found in northeastern Russia, and after a 30,000-year-long seal, they were revived again.
The complexity of these viruses is comparable to that of large prehistoric creatures, because the age they lived in is too far away from us, and there is a huge difference from the viruses that humans can control today, and the understanding of them is basically a blank piece of paper, which is why these prehistoric viruses are highly dangerous.
One might argue that while these prehistoric viruses may be powerful, they should not cause any real harm to humans if they are small, but according to the results of scientists' current investigations, the types and numbers of prehistoric viruses in glaciers and permafrost are beyond imagination.
A joint U.S.-China team sampled glaciers on the Tibetan Plateau in early 2020 and found that a total of 28 viruses that are currently unknown to the academic community were found in samples taken in a small area in the northwest alone, and that the youngest of these 28 species lived in a historical period of more than 15,000 years ago.
The impact of prehistoric viruses on humans was not sensational, but actually happened. In 2016, a reindeer exposed from the siberian permafrost was found, and shortly after that, more than 2,000 reindeer in the nearby area were infected with an infectious disease of unknown origin, and it was summer, and the source of infection spread rapidly, so it did not take long for these reindeer to begin to die on a large scale.
What's even more frightening is that people soon found similar symptoms in humans, and then the pathological analysis of the expert team concluded that this infectious disease is called anthrax, and it is a virus called anthrax that causes a large-scale outbreak, and the source of the virus is the reindeer in the permafrost, which died because of this virus.
The sensitivity and rapid response of medical experts allowed the spread of the virus to be strangled in the cradle in time and did not break out in the crowd, but it also sounded the alarm for us, what if it was not detected in time? What if that virus hasn't been mastered by human medicine yet? Just thinking about it makes people feel afraid.
<h1 class="pgc-h-arrow-right" data-track="21" > conclusion</h1>
Today, we have seen the power of infectious diseases caused by viruses, and in the continuous thawing permafrost, some distant unknown ancient viruses are waking up, what kind of severe challenges mankind will face, and what measures we should take to prevent problems before they occur, are all problems that need to be paid attention to and solved.
