In the 1940s, the pesticide DDT exploded in popularity. Ignoring warnings that it might poison the environment and endanger human health, corporations and governments sprayed the chemical for decades—until countries finally began outlawing its use, for precisely those reasons. On episode 47 of The Politics of Everything, hosts Laura Marsh and Alex Pareene talk with Elena Conis, the author of How to Sell a Poison: The Rise, Fall, and Toxic Return of DDT. They explore how corporations dismissed the dangers of DDT to protect profits, how pioneering environmentalists like Rachel Carson fought back, and why harmful chemicals may cause problems long after their usage has ceased.
