We know that U.S. industrial agriculture has had monumental effects on our climate, but how has climate change reciprocally impacted our agricultural system? And, an even more pressing question, how close is our agricultural system to total collapse? In his new book, “Perilous Bounty: The Looming Collapse of American Farming and How We Can Prevent It,” Tom Philpott looks for answers in the nation’s primary farming hubs: California’s Central Valley and the Corn Belt of the Midwest, both of which are in a state of accelerating ecological decline. Host Jenna Liut sits down with Tom to talk about California water barons, toxic petrochemical stews, and why we should make almonds a special occasion snack.
