It sold more than 2  million copies and went through 20 reprints by 1971. Ehrlich <a href=\"https:\/\/www.youtube.com\/watch?v=jQxLJCjH58s\">appeared more than 20  times on NBC\u2019s \u201cThe Tonight Show Starring Johnny Carson\u201d<\/a>, and became the first president of Zero Population Growth, a Washington D.C.\u2013based advocacy organization, while remaining a professor at Stanford.<\/p>\n<p>\u201cThe Population Bomb\u201d created more space to hold radical views on population matters, but its impact was fleeting, and maybe even harmful to the population movement. By the early 1970s, many critics were savaging Ehrlich and the larger goal of achieving zero population growth. And the politics of \u201cmorning in America\u201d in the 1980s successfully marginalized Erhlich as a doomsdayer.<\/p>\n<p>However, as a historian who has <a href=\"http:\/\/press.uchicago.edu\/ucp\/books\/book\/chicago\/S\/bo13590005.html\">studied<\/a> debates about population growth throughout U.S. history, I believe that Ehrlich\u2019s warnings deserve a new and less hysterical hearing. While Ehrlich has acknowledged significant errors, he was correct that lowering birth rates was \u2013 and remains \u2013 a crucial plank in addressing global environmental crises. <\/p>\n<figure class=\"align-center zoomable\">\n            <a href=\"https:\/\/images.theconversation.com\/files\/226791\/original\/file-20180709-122253-calowj.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip\"><img alt=\"\" src=\"https:\/\/images.theconversation.com\/files\/226791\/original\/file-20180709-122253-calowj.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip\"><\/a><figcaption>\n              <span class=\"caption\">Paul Ehrlich in 2010.<\/span><br \/>\n              <span class=\"attribution\"><a class=\"source\" href=\"https:\/\/commons.wikimedia.org\/wiki\/File:Paul_R_Ehrlich.png\">Paul R.

In his 1798 study, \u201c<a href=\"http:\/\/www.esp.org\/books\/malthus\/population\/malthus.pdf\">An Essay on the Principle of Population<\/a>,\u201d Malthus famously predicted that \u201cgeometric\u201d population growth would overwhelm \u201carithmetic\u201d gains in agricultural production, leading to wars, famines and societal collapse.  <\/p>\n<p>Fears of the potentially dangerous social and ecological effects of population growth intensified after World War II. Global population surged as public health improved greatly in developing nations, increasing life expectancy. At the same time, the new science of ecology demonstrated the fragility of Earth\u2019s interconnected systems. And the Cold War promoted worries that <a href=\"http:\/\/www.presidency.ucsb.edu\/ws\/?pid=25660\">population-induced poverty would breed communism<\/a>. <\/p>\n<p>Mainstream advocates of arresting population growth emphasized better access to family planning and education, but Ehrlich had no use for such baby steps. \u201cWell-spaced children will starve, vaporize in thermonuclear war, or die of plague just as well as unplanned children,\u201d he wrote. <\/p>\n<figure>\n            <iframe loading=\"lazy\" width=\"440\" height=\"260\" src=\"https:\/\/www.youtube.com\/embed\/PUwmA3Q0_OE?wmode=transparent&amp;start=0\" frameborder=\"0\" allowfullscreen><\/iframe><figcaption><span class=\"caption\">It took 200,000 years for Earth\u2019s human population to reach 1 billion \u2013 and only 200 years to reach 7 billion.

But Erhlich, <a href=\"https:\/\/theconversation.com\/farmers-and-cropdusting-pilots-on-the-great-plains-worried-about-pesticide-risks-before-silent-spring-91976\">echoing a growing chorus of farmers and agricultural scientists<\/a>, warned that pesticides ruined the environment and would eventually backfire as weeds and pests developed resistance. <\/p>\n<p>Erhlich never called population the only variable. With physicist <a href=\"https:\/\/www.belfercenter.org\/person\/john-p-holdren\">John Holdren<\/a>, he proposed the <a href=\"https:\/\/e4anet.files.wordpress.com\/2014\/09\/610_wk1-ehrlich-and-holdren-one-dimensional-ecology.pdf\">I = P x A x T formula<\/a>, which describes human impact as the product of population, affluence (the effects of consumption) and technology. <\/p>\n<p>Nonetheless, Ehrlich believed that population was the key multiplier and massive reductions in global population were critical for human survival. He hoped that a combination of policy carrots and sticks would reduce fertility sufficiently and preserve voluntary family planning. But he held out the possibility that coercive measures, <a href=\"https:\/\/www.smithsonianmag.com\/innovation\/book-incited-worldwide-fear-overpopulation-180967499\/\">including compulsory sterilizations<\/a>, might be needed.<\/p>\n<h2>Backlash and a new population politics<\/h2>\n<p>Millions of Americans shared Ehrlich\u2019s anxieties in 1968. Concerns about the ecological impact of global population growth had <a href=\"https:\/\/www.amazon.com\/Malthusian-Moment-Population-Environmentalism-Environment\/dp\/0813552729\">helped birth modern American environmentalism<\/a>. Feminists cited overpopulation to buttress the case for reproductive and abortion rights. Politicians on both sides of the aisle urged action to lower birth rates, and Republican President Richard Nixon signed into law a Commission on Population Growth and the American Future. <\/p>\n<p>But the \u201cculture wars\u201d of the 1970s subsumed and reconfigured population issues. On the right, the \u201cpro-life\u201d movement that crystallized in the wake of the Supreme Court\u2019s 1973 <a href=\"https:\/\/theconversation.com\/how-roe-v-wade-changed-the-lives-of-american-women-99130\">Roe v. Wade decision<\/a> considered any talk of population reduction anathema. <\/p>\n<p><a href=\"https:\/\/www.npr.org\/2016\/02\/01\/465124337\/how-chinas-one-child-policy-led-to-forced-abortions-30-million-bachelors\">China\u2019s one-child policy<\/a>, launched around 1980, led to serious human rights abuses that allowed anti\u2013family planning conservatives to paint all population programs in a negative light. Conservatives subsequently ignored China\u2019s significant reforms to the policy, as well as research indicating that slowing population growth <a href=\"http:\/\/dx.doi.org\/10.1136\/bmj.38938.412593.80\">contributed to China\u2019s economic miracle<\/a>. <\/p>\n<p>Moreover, newly ascendant anti-Keynesian economists rejected an older consensus that slowing population growth would yield economic benefits. These market-oriented economists asserted that denser populations created economies of scale, and that individual fertility decisions would adjust to any temporary population problems. President Ronald Reagan, who once had dabbled with Malthusianism, tellingly labeled advocates who worried about scarce resources \u201c<a href=\"https:\/\/books.google.com\/books?id=F8V-YzywyaIC&amp;pg=PA209&amp;lpg=PA209&amp;dq=ronald+reagan+doomsday+crowd&amp;source=bl&amp;ots=EpxPTC-lbO&amp;sig=MNQ7S3aX0s3EU8kdjP_R3eMNjWo&amp;hl=en&amp;sa=X&amp;ved=0ahUKEwi4qtzptIjcAhWqzlkKHSTiAGkQ6AEIcDAT#v=onepage&amp;q=ronald%20reagan%20doomsday%20crowd&amp;f=false\">Doomsday prophets<\/a>.\u201d<\/p>\n<figure class=\"align-center zoomable\">\n            <a href=\"https:\/\/images.theconversation.com\/files\/226792\/original\/file-20180709-122277-g2q5o.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip\"><img alt=\"\" src=\"https:\/\/images.theconversation.com\/files\/226792\/original\/file-20180709-122277-g2q5o.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip\"><\/a><figcaption>\n              <span class=\"caption\">As nations develop economically, couples have fewer children and fertility rates decline.<\/span><br \/>\n              <span class=\"attribution\"><a class=\"license\" href=\"http:\/\/creativecommons.org\/licenses\/by-nd\/4.0\/\">CC BY-ND<\/a><\/span><br \/>\n            <\/figcaption><\/figure>\n<p>After Congress <a href=\"https:\/\/www.history.com\/topics\/us-immigration-since-1965\">eliminated national-origin immigration quotas<\/a> in 1965, immigration rose steadily and accounted for a growing share of population growth in the U.S. In this context, white liberals increasingly risked being branded racist for supporting population reduction. <\/p>\n<p>By the late 1970s, both liberals and conservatives had bought into exaggerated talk of an \u201caging crisis\u201d \u2013 too few workers to pay for the bulge of baby boomers headed toward retirement.
