A terrible fact! When humans dominate the wilderness, animals carrying viruses will follow!
As we all know, the earth is our living place, the source of food and clothing. Since the development of human beings, human activities have greatly changed the face of the earth. According to the data, about 300 years ago, we only occupied 5% of the earth’s land resources. Now, with the continuous development of society and the continuous growth of population, it is very difficult to see that there is no land at all Human beings have been involved in the area, 95% of the earth’s land surface area has the sign of man-made transformation.
Therefore, some people have raised a question: is it more convenient for animals carrying pathogenic pathogens to transform the natural environment into human land on such a large scale?
Generally speaking, the smaller the organisms are, the more adaptable they are to nature. So mice and mosquitoes, for example, are small in size, large in number, and have very low requirements for food and living environment. Some experts pointed out that these organisms are often carriers of pathogenic bacteria.
While we continue to expand human land, we also unintentionally increase the number of them, increasing the risk of diseases or infectious diseases that we share with them.
Therefore, some experts have carried out in-depth research. They use rigorous criteria to determine the association between the host and the pathogen. The use of land by human beings is increasing, and so are the hosts and organisms that are likely to carry pathogens.
Because the source of this year’s cowid-19 pandemic is likely to come from these animals, so zoonotic diseases have also attracted great attention of human beings.
Along with this, people generally have a wrong understanding: wild animals are the biggest source of diseases shared by human and animals. Describing the jungle as a mass culture full of microbial threats and some early scientific research reinforce this view.
However, experts believe that in the natural environment, the greatest threat of zoonotic diseases occurs in areas that have been transformed into arable land, pastures and urban areas.
With the increasing number of animals due to human land use, they are not only more likely to become pathogen hosts, but also more likely to carry more pathogen species, including more pathogens that can infect humans.
The latest research has solved the same common problem with different methods, and found that the number of zoonotic viruses carried by more and more widespread and abundant mammals is decreasing, while the number of threatened or endangered species is more.
This finding provides evidence for previous studies to find a compromise between the high reproductive rate associated with ecological restoration and the high immune system investment associated with low disease load.
In other words, organisms with a life history similar to that of mice seem to be more resistant to infection than other organisms. Another non exclusive explanation is that generalized pathogens (more likely to spill over to new hosts) tend to target the hosts they are most likely to encounter in the evolutionary process through adaptation. These hosts are mice in the world, not other larger organisms.
This has to cause Xiaobian’s thinking, if the earth’s land resources, and even other resources are over exploited by us, to a certain limit, what terrible things will happen!
The ending is so terrible that it’s frightening. Interstellar exploration and development is too important for human survival in the future. We hope that science and technology can change life and the future of mankind.
