"Rats and bats that host pandemic pathogens like Covid-19 increase in damaged ecosystems, analysis shows"
"The human destruction of natural ecosystems increases the numbers of rats, bats and other animals that harbour diseases that can lead to pandemics such as Covid-19, a comprehensive analysis has found.
The research assessed nearly 7,000 animal communities on six continents and found that the conversion of wild places into farmland or settlements often wipes out larger species. It found that the damage benefits smaller, more adaptable creatures that also carry the most pathogens that can pass to humans.
The assessment found that the populations of animals hosting what are known as zoonotic diseases were up to 2.5 times bigger in degraded places, and that the proportion of species that carry these pathogens increased by up to 70% compared with in undamaged ecosystems."
