'Promiscuous treatment of nature' will lead to more pandemics - scientists
Habitat destruction forces wildlife into human environments, where new diseases flourish Humanity’s “promiscuous treatment of nature” needs to change or there will be more deadly pandemics such as Covid-19, warn scientists who have analysed the link between viruses, wildlife and habitat destruction.
Deforestation and other forms of land conversion are driving exotic species out of their evolutionary niches and into manmade environments, where they interact and breed new strains of disease, the experts say.
...A growing body of research confirms that bats – the origin of Covid 19 – naturally host many viruses which they are more likely transfer to humans or animals if they live in or near human-disturbed ecosystems...In the wild, bats are less likely to transfer the viruses they host to other animals or come into contact with new pathogens because species tend to specialise within distinct and well-established habitats. But once land is converted to human use, the probability increases of contact and viruses jumping zoonotically from one species to another.
...South America is a key area of concern due to the rapid clearance of the Amazon and other forests. Scientists in Brazil have found viral prevalence was 9.3% among bats near deforested sites, compared to 3.7% in pristine woodland. “With deforestation and land-use change, you open a door,” said Alessandra Nava, of the Manaus-based Biobank research centre.
...Conservation groups have also urged greater protection of existing habitats. A recent Greenpeace report warned the Amazon could see the next spillover of zoonotic viruses because the Brazilian president, Jair Bolsonaro, is putting a higher priority on opening up the forest than protecting people’s health...
