Paul Ehrlich: The man who bet England wouldn’t exist by the year 2000

The late biologist Paul Ehrlich’s 1968 bestseller, *The Population Bomb*, predicted a global apocalypse driven by overpopulation and inevitable mass starvation. While Ehrlich correctly anticipated the human population would more than double to over 8 billion, his dire forecasts of a collapsed United Kingdom and a skyrocketing global death rate failed to materialize. This discrepancy stems largely from the "Green Revolution," where innovations in high-yield crops, synthetic fertilizers, and pesticides increased cereal yields by 250% since 1961, allowing food production to outpace population growth. Experts Vincent Geloso, Peter Alexander, and Darrell Bricker note that Ehrlich viewed humans through the lens of insect biology, overlooking the capacity of the creative human mind to engineer new resources. Today, global death rates have halved since the 1960s, and modern famines are typically the result of political conflict rather than an inability to produce sufficient food. Despite shifting his focus to biodiversity and sustainability in later years, Ehrlich’s legacy remains defined by these unfulfilled cataclysmic predictions.
