Overview
- Ehrlich’s 1968 bestseller vaulted him to global prominence by predicting imminent mass starvation and resource collapse from rapid population growth.
- Subsequent decades contradicted his dire forecasts as the global population rose to roughly 8.1 billion while large famine deaths and undernourishment rates declined with gains from the Green Revolution and global trade.
- His advocacy influenced government actions ranging from expanded family‑planning programs to coercive sterilizations in India and China’s one‑child era, according to contemporary reassessments.
- Critics long cited his losing 1980–1990 wager with economist Julian Simon on resource prices as a practical refutation of his scarcity thesis.
- He remained unapologetic late in life, reiterating overpopulation warnings in a 2023 interview that declared humanity’s current path unsustainable.
