His famous 1968 book, “The Population Bomb,” changed the world. He famously predicted that human “overpopulation” would soon outstrip food supplies, leading to catastrophic famines, and societal collapse. He predicted that hundreds of millions of people would starve to death in the 1970s and 1980s, that India would be unable to feed its population by 1980, and that major countries like England would no longer exist by the year 2000.
