Intensive farming makes future pandemics such as Covid-19 more likely as wild animals carrying diseases known to infect humans are forced into increasingly close contact with us, a research report showed on Wednesday.
Writing in the journal Nature, a team of researchers from University College London (UCL) warned that animal pathogens are increasingly likely to make the leap to humans as land-use changes benefit animal hosts.
The UN estimates that three-quarters of land on Earth has been severely degraded by human activity since the start of the industrial era.
