On this week’s How on Earth, Beth talks with author and science journalist Liz Kalaugher, about her new book, The Elephant in the room:How to Stop Making Ourselves and Other Animals Sick. Think about it this way: When new diseases spread, news reports often focus on wildlife culprits–rodents, monkeys and mpox; bats and COVID-19; waterfowl and avian flu; or mosquitoes and Zika. But, as Liz points out, we see it often works the other way around–humans have caused diseases in other animals countless times, through travel and transport, the changes we impose on our environment, and global warming. In her deeply researched and often entertaining book, Liz introduces the wildlife we have harmed and the experts now studying the crosscurrents between humans, other animals, and health.

In addition to headlines about this issue, we replay an interview with author John Vaillant, who has written extensively about the natural world over his long career. In his new book, Fire Weather:A True Story from a Hotter World, he explores the phenomena of fire, the wildland urban interface, and climate change in the context of a precedent-shattering combustion in a modern city.This colossal wildfire in Alberta in 2016 almost consumed a city of nearly 100,000. In the process the fire blew up expectations and responses to wild fires.
