# Paul Ehrlich Stanford biologist (1932–2026) whose *[[The Population Bomb]]* (1968) made overpopulation a mass-audience emergency — "the battle to feed all of humanity is over," it opened; hundreds of millions would starve in the 1970s — and launched the modern American population-control movement. He died on March 13, 2026, at 93, after 67 years on the Stanford faculty. The vault's interest is a specific lineage: from the bestseller to [[Zero Population Growth]] (which he co-founded in 1968) to the advisory board of [[FAIR]], the flagship of [[John Tanton]]'s restrictionist network — the clearest institutional link between mainstream environmental population politics and immigration restriction. ## The scientist and the prophet Ehrlich's science was real and durable: a butterfly ecologist whose 1964 paper with Peter Raven introduced coevolution as a field, founder of Stanford's Center for Conservation Biology, a MacArthur Fellow and Crafoord laureate, author of 700 papers and 30 books, most with his wife and collaborator of 72 years, Anne Ehrlich. The prophecy was another matter. The famines did not come — the Green Revolution and the demographic transition arrived instead ([[Malthusianism]] has the mechanism) — and in 1980 the economist Julian Simon bet him that five metals of Ehrlich's choosing would be cheaper in 1990. Ehrlich lost on all five and paid $576. He never conceded the larger point, and *The Population Bomb*'s failed dates became the standing argument against every later environmental warning, climate included — the cost to the movement's credibility that the [[Carrying Capacity]] page reckons with. ## The restrictionist turn The population argument had to answer "whose births," and in the United States in the 1970s the answer the movement reached for was immigration. Ehrlich's own text had countenanced compulsion — "population control at home, hopefully through a system of incentives and penalties, but by compulsion if voluntary methods fail" — and ZPG's presidency passed in 1975 to Tanton, who founded FAIR from it in 1979 with [[Cordelia Scaife May]]'s money. Ehrlich sat on FAIR's advisory board for years and co-wrote *The Golden Door* (1979), on Mexican immigration, with Anne and Loy Bilderback. He was not a nativist in Tanton's sense — his framing stayed numerical, and he broke with the harder line later — but his authority is what let a numbers argument carry the [[Passive Eugenics]] program the Tanton papers describe. [[Garrett Hardin]] is the other scientist in that chain; [[NumbersUSA]] and the [[Immigration Restrictionism Ecosystem]] are where it ended up. ## See Also - [[The Population Bomb]] · [[Zero Population Growth]] · [[Carrying Capacity]] · [[Malthusianism]] · [[Garrett Hardin]] - [[FAIR]] · [[John Tanton]] · [[Tanton Network]] · [[Cordelia Scaife May]] · [[Passive Eugenics]] · [[Immigration Restrictionism Ecosystem]] · [[NumbersUSA]]
