Paul Ehrlich opened his 1968 e-book “The Population Bomb” with a scene recounting returning to his lodge via a crowded Delhi community on a stifling evening within the mid-Nineteen Sixties. He described the bodily sensation of overpopulation: other people consuming, washing, arguing, begging – “people, people, people, people.”
From that visceral opening, he declared that famine, war and nuclear conflict would sweep the globe within the Nineteen Seventies on account of overpopulation. Loads of thousands and thousands of other people would starve to loss of life irrespective of any crash systems introduced to forestall it. Ehrlich argued for inhabitants keep watch over, chillingly describing inhabitants expansion as a “cancer” that had to be reduce out.
Ehrlich’s predictions have been conspicuously incorrect – and professionals stated so on the time. However his common sense resonated in the course of the Nineteen Seventies and ’80s around the political spectrum. Its shadow is obvious in lately’s anti-immigration campaigns and White Area arguments for mass deportation.
We’ve adopted its lengthy afterlife, as a computational social scientist finding out recent extremism and as a historian whose e-book “Building the Population Bomb” analyzed Ehrlich’s affect.
Getting it incorrect
Demographers and economists within the many years after International Conflict II rejected the concept that Ehrlich was once selling to thousands and thousands of readers: that inhabitants expansion is the main reason for environmental degradation. As a substitute, the knowledgeable consensus confirmed how air pollution and useful resource depletion are pushed way more by means of extraction and overconsumption than by means of head depend.
Princeton demographer Ansley Coale advised the Inhabitants Affiliation of The usa in 1968, the yr “The Population Bomb” was once revealed, that attributing nationwide screw ups to inhabitants expansion had turn out to be stylish in spite of many of the nation’s issues having little to do with it.
His colleague and previous Inhabitants Affiliation of The usa president Frank Notestein demonstrated on the affiliation’s 1970 assembly that will increase in air pollution had a ways outpaced will increase in inhabitants. Notestein referred to as inhabitants keep watch over in “developed regions” a distraction from the extra fast want to control trade.

Ecologist Barry Commoner’s 1971 empirical find out about showed that postwar environmental harm had stemmed nearly totally from new manufacturing strategies and emerging consistent with capita intake, no longer from the rising choice of other people. When the economist Julian Simon challenged Ehrlich in 1980 to a bet on adjustments in commodity costs over the following decade, Ehrlich approved – and misplaced.
In a 2009 retrospective, Ehrlich stated a few of “The Population Bomb’s” flaws however didn’t revisit its central declare. The mass famines he predicted had no longer materialized within the Nineteen Seventies as a result of he had no longer expected the Inexperienced Revolution, a dramatic growth of agriculture output. He stated the e-book’s catastrophic eventualities have been illustrative workout routines, no longer inevitable forecasts. He disregarded his critics as shills for polluters. Ehrlich’s retrospective concluded, “It was thus a successful tract, and we’re proud of it.”
Origins of the ‘population bomb’ analogy
Ehrlich’s arguments resonated with the preferred anxieties of the past due Nineteen Sixties. Via tying inhabitants expansion to the surroundings, the specter of nuclear conflict and the sexual revolution, Ehrlich generated left-wing reinforce for inhabitants keep watch over, which had prior to now been basically a priority of the political proper.
With the e-newsletter of “The Population Bomb,” Ehrlich was a star nearly in a single day. Even though his claims concerning the penalties of inhabitants expansion have been constantly incorrect, Ehrlich had a huge public affect. A butterfly biologist, he was once abruptly reserving appearances on Johnny Carson’s “Tonight Show.” He influenced dystopian Hollywood productions, similar to “ZPG” (1972), “Soylent Green” (1973) and “Logan’s Run” (1976).

The highbrow family tree at the back of “The Population Bomb” ran deeper than Ehrlich’s personal profession. The “bomb” analogy was once borrowed from a 1954 pamphlet by means of Hugh Moore, a businessman whose inhabitants anxieties descended from Man Irving Burch, the anti-immigrant eugenicist who based the Inhabitants Reference Bureau in 1929.
Burch, apprehensive about “alien or negro stock” changing Europeans, offered the word “population explosion” to American public discourse within the Thirties as a part of a marketing campaign for immigration restriction. Moore up to date Burch’s framework for the Chilly Conflict, caution that inhabitants expansion in Africa, Asia and Latin The usa would produce communist growth and nuclear conflict.
Ehrlich’s use of ecological sporting capability – the concept that any setting has a finite choice of assets to reinforce a inhabitants earlier than collapsing – justified coercive inhabitants keep watch over tasks as international and home environmental insurance policies within the minds of many American citizens.
India’s “Emergency” duration from 1975-77 subjected an estimated 8 million other people to sterilization below prerequisites starting from monetary inducement to outright coercion. China’s one-child coverage was once enforced via fines, compelled sterilizations and forced abortions for just about 3 many years. Inhabitants keep watch over systems in some growing international locations imposed birth control and sterilization on girls with out their consent.
California carried out sterilizations on some inmates till the 2010s. Hysterectomies on detainees persevered in a minimum of one U.S. Immigration and Customs Enforcement detention middle till 2019.
Ehrlich tied setting to immigration
Inside the USA, Ehrlich co-founded the group 0 Inhabitants Enlargement, which briefly outlasted its unique premise. Via 1972, the overall fertility price in the USA was once already under the substitute degree, and ZPG pivoted to immigration restriction as its number one coverage goal.
David Brower, the primary director of the Sierra Membership, authored the well-known line “the battle to feed all of humanity is over” within the foreword to “The Population Bomb.” He appointed John Tanton, Ehrlich’s ZPG co-founder, to chair the Sierra Membership’s nationwide inhabitants committee.
Tanton would pass directly to construct a community of teams that might put in force the common sense Ehrlich had popularized. This common sense related Ehrlich’s ecological sporting capability, lifeboat ethics – the concept that rich international locations risked being swamped by means of immigration – and reactionary anxieties about demographic alternate.
Tanton’s anti-immigration community was probably the most influential organizations in late-Twentieth-century American politics. Along with ZPG, Tanton based the Federation for American Immigration Reform (FAIR) in 1979, the Middle for Immigration Research in 1985, The Social Contract Press in 1990 and NumbersUSA in 1996.
This community produced coverage analysis and lobbied for drastic discounts in each prison and unlawful immigration. It was once additionally instrumental in repackaging nativism into genteel coverage briefs for the 1994 Republican revolution, securing the bipartisan passage of the Unlawful Immigration Reform and Immigrant Duty Act of 1996, and backing anti-immigration efforts that handed in California and Arizona. Ehrlich served on FAIR’s board of advisers till 2002. He died on March 13, 2026.
Ehrlich, Tanton and Brower, as a part of Californians for Inhabitants Stabilization, attempted to push the Sierra Membership to undertake immigration restrictions as an professional place, however individuals of the influential environmentalist crew resisted. Poll measures and board elections for the Sierra Membership from the past due Nineteen Nineties into the early 2000s uncovered the deep ties to anti-immigration activists – and defeated them.
Overpopulation in politics lately
Ehrlich’s inhabitants anxieties proceed to have a protracted afterlife as political figures construct on the concept that immigration constitutes a type of “replacement” of present populations. As soon as-fringe grievances suggesting white other people have been being changed by means of other people of colour have turn out to be a part of President Donald Trump’s MAGA allies’ “mass deportation now” time table.
Fifty years separate India’s sterilization camps from lately’s ICE detention warehouses, however we consider the common sense connecting them is direct: a inhabitants outlined as over the top, a central authority equipment approved to scale back it, and a systematic vocabulary utilized by one of the most president’s closest allies to justify the approach as an ecological necessity. Ehrlich’s contributions to that vocabulary proved way more sturdy than his predictions.
