L ' loss of biodiversity has increased the number of animal pathogens responsible for the increase of infectious diseases . So the man upsetting the ecosystem may cause harm even more worse for your health. This is the framework set by a search of the Bard College in Annandale (New York), in collaboration with National Science Foundation (NSF)-National Institutes of Health (NIH), Ecology of Infectious Diseases (EID) Program.
Lo scomparire di specie animali a causa dell'intervento dell'uomo sulla natura con deforestazione e caccia, spiegano i ricercatori, guidati dalla dottoressa Felicia Keesing , può essere pericoloso per la salute perché, è stato dimostrato, se diminuiscono le specie animali esistenti sulla terra aumenta la trasmissione di organismi patogeni come batteri, virus e funghi .
Dallo studio, pubblicato sulla rivista Nature, emerge che la biodiversità a livello mondiale è scesa a un ritmo senza precedenti dal 1950: con tassi di estinzione stimati dalle 100 alle 1000 volte di più compared to past times, is expected to continue to increase dramatically over the next 50 years.
" species that tend to disappear are often those that block the transmission of infectious diseases ," says the study. To get a better idea of \u200b\u200bthe risk of increased disease in humans, due to impoverishment of the fauna global Sam Scheiner, program director of the Ecology of Infectious Diseases at the National Science Foundation: "Global change is accelerating, bringing with it a host of unintended consequences. This paper shows that the extinction of various animal species may lead to increases in the incidence of diseases for humans, animals and plants ".. Pathogens, without opposition, to more easily, their targets, as the plants can also be natural barriers, weakening them.
Scientists believe therefore that to maintain the barriers against disease is even more necessary to protect the environment and the creatures that inhabit it .
