7. The Tree Sparrow: Mao's Folly and the Emu Wars



AUTHOR: Stephen Moss

BOOK TITLE: 10 Birds That Changed the World

This excerpt details Mao's 1958 "Four Vermin" campaign targeting the Tree Sparrow. Maoordered the sparrows killed, believing they consumed grain; however, because sparrows feed their young on insects, their eradication led to an insect population boom. The subsequent crop failures caused a famine that resulted in potentially 45 to 50 million deaths, making it the worst human-created disaster in history. The segment contrasts this tragedy with the "Emu Wars" in 1930s Australia, where highly adaptable Emussuccessfully defeated the Australian army.




1938
