Sonia Shah is an investigative science journalist and author of “Pandemic: Tracking Contagions, from Cholera to Ebola and Beyond.” Her new book is titled “The Next Great Migration: The Beauty and Terror of Life on the Move” and will be published in June. She says the climate crisis is making outbreaks of infectious diseases more common, with the destruction of natural animal habitats and the changes in migration bringing humans and animals into ever-closer contact and making new pathogens more likely. Her latest article, published in The Nation, is titled “Think Exotic Animals Are to Blame for the Coronavirus? Think Again.”
