“About two-thirds of emerging infectious diseases in humans — including COVID-19, SARS, MERS, Ebola, HIV, Zika, H1N1, cholera and almost all recent epidemics — came from animals. And 70% of those originated in wildlife.
Pathogens have leaped from animals to humans for eons, but the pace of this spillover has increased rapidly over the last century. As 7.8 billion people on this planet radically alter ecosystems and raise, capture and trade animals at an unprecedented scale, “the road from animal microbe to human pathogen” has turned into a “highway,” as the journalist Sonia Shah has written.
The growing body of scientific research is clear: Diseases like COVID-19 are an expected consequence of how we’re choosing to treat animals and their habitats.
By changing the nature and frequency of human-animal interactions, our actions — through the wildlife trade, deforestation, land conversion, industrial animal farming, the burning of fossil fuels, and more — propel the emergence and transmission of novel and known human infectious diseases.”
