📰 The planet of pandemics

If climate change leads to the displacement of animal populations, this means that the risk of virus exchange between different species increases. And what about us?

Remember that the vast majority of virus (A virus is a biological entity that a host cell needs, uses…) are exclusive to a kind (In the life sciences, the species (from the Latin species, “type”…)† But with the amount of (The quantity is a general term from metrology (account, amount); a scalar,…) of viruses circulating, this has led through all eras to a number (The concept of number in linguistics is covered in the article “Number…) raised that, at chance (In plain language, the word chance is used to express a lack of efficiency, otherwise…) of one mutation, became capable of being passed on to another species. And sometimes to us. The learned name is zoonosis (A zoonosis (from the Greek son, “animal” and nosos,…): a infectious disease (An infectious disease is a disease caused by the transmission of a…) that went from a animal (An animal (from the Latin animus, spirit or vital principle) is according to the classical classification a…) to man. The pandemic (A pandemic (from Ancient Greek πᾶν / pãn (all) and…) of COVID-19 is a zoonosis, even though we are not yet sure of the animal of origin.

By changing from territory (The concept of territory has become increasingly important in geography and in particular in…)so an animal can cross the road away (The word “way” is derived from the Latin (via) rupta, literally “way…) of an animal he would never have met before. Does this increase the risk of disease transmission between species? Yes, say researchers who mathematical model (A mathematical model is a translation of reality in order to be able to apply the tools to it,…) of 3,139 mammalian species and the 40,000 viruses known to date from which they originate the hosts (The Hostess is a science fiction short story by Isaac Asimov, published for the…), as well as their current and probable movements over the next 50 years. Their conclusion is that in the next 50 years we can predict 4,500 conditions in which a virus, or even several viruses, can “jump” from one species to another. The article appeared on April 28 in the magazine Nature

Until now, the biologists interested in this matter would rather have gone there virus by virus: will it survive such and such environmental change, does it have mutations that could allow it to “jump” to another species .

However, it is with the magnitude of the problem – these 4500 possibilities – that a signal (General terms A signal is a simplified and commonly coded message. There is…) alarm for man. When the researchers assessed where these problematic species would have migrated in 50 years, they found that the vast majority were areas where our cities are expanding. For example, note in the New York Times pathology ecologist Gregory Albery, co-author of the study, a small rodent that had had little contact with humans until then was able to transmit its virus to a raccoon living comfortably in urban areas.

In fact, it has already started, as the figures for the last century (A century is now a period of a hundred years. The word comes from the Latin saeculum, i, which…) reveal that 60% of the new epidemics that have hit us are zoonoses. The likely result of unprecedented contacts in the 20th century between humans and certain animal species, such as batsAsia (Asia is one of the five continents or part of the supercontinents Eurasia or Afro-Eurasia of the…) by South East (Southeast is the direction halfway between the southern and eastern cardinal points. Southeast is…)

Incidentally, the researchers note that there are concerns about the impact of these new viruses on humans, but it should not be forgotten that for an already vulnerable animal population, a new virus against which immune system (An organism’s immune system is a coordinated set of elements of…) being unprepared can have a devastating impact.

the journalist (A journalist is a person whose professional activity is journalism. We’re talking…) Ed Yong uses the word “pandemicene” – we would have entered a “pandemic era” in which a large number of new hosts will transmit old viruses, and perhaps even new ones. This one situation (In geography, situation is a spatial concept that defines the relative location of a…) was created by the crash (A collision is a direct impact between two objects. Such an impact sends part of…) between two of the impacts humans have on nature: climate change and habitat loss for wildlife. And this situation, Yong concludes, is at the intersection of three of our existential fears: “climate change, pandemics and the 6th become extinct (In general, the word extinct refers to an action that consists of extinguishing something…) by mass (The term mass is used to denote two quantities attached to one…)” of the to live (Life is the given name 🙂 secure Soil (Earth is the third planet in the solar system in order of distance…)† “These three fears are actually the same mega problem.” As we emerge from a pandemic, he warns, we would do well not to underestimate the importance of better preparing for the next…
