BOB ZUBRIN: The Population Control Holocaust. “There is a single ideological current running through a seemingly disparate collection of noxious modern political and scientific movements, ranging from militarism, imperialism, racism, xenophobia, and radical environmentalism, to socialism, Nazism, and totalitarian communism. This is the ideology of antihumanism: the belief that the human race is a horde of vermin whose unconstrained aspirations and appetites endanger the natural order, and that tyrannical measures are necessary to constrain humanity. . . . Its most pernicious manifestation in recent decades has been the doctrine of population control, famously advocated by ecologist Paul Ehrlich, whose bestselling 1968 antihumanist tract The Population Bomb has served as the bible of neo-Malthusianism. In this book, Ehrlich warned of overpopulation and advocated that the American government adopt stringent population control measures, both domestically and for the Third World countries that received American foreign aid. (Ehrlich, it should be noted, is the mentor of and frequent collaborator with John Holdren, President Obama’s science advisor.)”
