A Newsweek magazine feature back in 1975 was headlined "The Cooling World." (Journalists beware: The supposed 1977 Time magazine cover story "How to Survive the Coming Ice Age" is among the countless frauds that infest the Internet.)
Eventually, cultural concern shifted instead to "global warming" (which was then rebranded as "climate change").
Seven years before Newsweek's freeze alarm, Stanford University biologist Paul Ehrlich published his apocalyptic "The Population Bomb," which sold in the millions and updated Thomas Malthus's dire demographic predictions from 1798. Ehrlich warned, for example, that due to global overpopulation, in the 1970s "hundreds of millions of people are going to starve to death." He then helped found the Zero Population Growth organization (since rechristened Population Connection).
Now comes The New York Times with a major page-one May 23 feature headlined "Long Slide Looms for World Population, With Sweeping Ramifications." We're told fertility rates are falling most everywhere except Africa south of the Sahara Desert, and that experts project the first population decline in world history will take hold by the end of this century. Click here for tmatt’s podcast and first take on some of the religion hooks in that story.
Stagnant and shrinking populations will thrill a segment of environmentalists, but these trends also destabilize society — which creates news. Whether with the shared responsibilities families have always assumed, or modern-day governments' social security systems, humanity must have enough younger workers carrying older people to sustain itself.
To keep the population stable, a society needs 2.1 children in the average nuclear family. A survey in The Lancet last year predicted that 183 of the world's 195 nations and territories are on a path to fall below that mark.
The particulars are staggering. The United States is well below that replacement number, and India and Mexico are nearly there, but South Korea has plummeted to a remarkable 0.92.
