Population

I am sorry to hear of the death of Stanford University Professor of Biology Paul R. Ehrlich at the age of 93, but to read his writings you wonder whether it is an event he might actually want us to celebrate. It does, after all, mean one less mouth to feed. Just another 6.5 billion people to go and we will be down to what in 2018 he stated was the world’s optimum population of between 1.5 to 2 billion. Ehrlich’s 1968 book, The Population Bomb – written with his wife Anne whose name his publisher famously kept off the front cover – established Ehrlich as the world’s latter-day Malthusian-in-chief.

One sign of moral panic is that when the facts change, the fears remain the same. In the 1970s, the Washington Post, TIME and Newsweek stoked fears of “a new ice age.” As soon as scientists updated their models to show a trend in the other direction, “global warming” became as threatening as global cooling. And when winters stubbornly kept happening and the direst predictions of new-age prophets like Al Gore failed to come to pass, the whole thing was rebranded as “climate change.” Whatever the label, and whatever the underlying phenomenon was thought to be, the moral implication remained the same — human beings were ruining the earth and must curtail their comforts to save the planet. Bad weather used to be God’s punishment for human sinfulness.
