Roughly two-thirds of emerging infectious diseases — including COVID-19 and almost all recent epidemics — originate in the bodies of animals. Microbes have spilled over from animals to humans for time immemorial, but, as our species dominates the biosphere and transforms the frequency and nature of human-animal interactions, the rate at which microbes are jumping the species barrier is rapidly accelerating. In this episode, we speak with investigative journalist Sonia Shah, author of “Pandemic: Tracking Contagions from Cholera to Ebola and Beyond,” about the history of viral infections and how our treatment of animals and the planet — via the burning of fossil fuels, biodiversity loss, deforestation, factory farming, the wildlife trade, and more — is fueling the eruption and spread of infectious diseases.
Nonhuman beings, and the passionate people who study them, animate Ed Yong’s vast, award-winning and kaleidoscopically varied body of journalism. His vivid stories explore the lives of scientists, the origins of life, social policy, whale hearts, the sixth extinction, the individuals we lose when a species vanishes or populations shrink, and the communities of tiny microbial beings that make us ourselves. To be at all, Yong demonstrates, is to be in partnership with other animals. In this episode, we speak with Yong about the wonders and burdens of telling stories about the animal world.
