The Four Pests Campaign: How Killing Sparrows Backfired | Smartest Year Ever (Oct 9, 2025)

In 1958, Mao Zedong launched the Four Pests Campaign as part of the Great Leap Forward, a nationwide effort to eliminate rats, flies, mosquitoes, and sparrows. The goal was to protect crops and public health. Instead, it spiraled into one of the greatest ecological disasters in modern history.

Gordy takes you inside this story of pots, pans, and sparrows falling from the sky, showing how a war against nature turned into an unintended famine-inducing catastrophe. Learn how sparrow extermination caused locust swarms, worsened the Great Chinese Famine, and forced China to import sparrows from the Soviet Union just to restore balance.

This episode explores the consequences of ignoring ecological complexity, the human cost of political campaigns, and why the Four Pests Campaign is remembered today as one of the most infamous policies of the 20th century.

If you’ve ever wondered how a campaign meant to save grain ended up starving millions, this is the story.
