Mao's War on Sparrows and Australia's Emu Conflict Guest: Stephen Moss Book Title: Ten Birds That Changed the World In 1958, Mao Zedong ordered the eradication of the tree sparrow as part of his "Four Pests" campaign, believing it would save grain. The mass slaughter — carried out by citizens banging pots until birds dropped dead from exhaustion — caused an ecological disaster. Without sparrows to eat them, insect populations exploded and consumed the harvests, leading to a famine that killed up to 50 million people. Scientists like Tso-hsin Cheng who tried to warn Mao were persecuted, and China was eventually forced to import sparrows from the Soviet Union to restore the ecosystem. In a lighter but equally revealing tale, Moss recounts Australia's 1932 Emu War, where the military failed to cull 20,000 emus with machine guns. The emus used tactical "guerrilla" maneuvers to outwit the soldiers, proving that human attempts to militarily intervene in nature often end in humiliation or catastrophe. (7)
