Human populations are set to decline in countries from Asia to Europe – and an unusual form of rewilding is taking place
For many years it seemed that overpopulation was the looming crisis of our age. Back in 1968, the Stanford biologists Paul and Anne Ehrlich infamously predicted that millions would soon starve to death in their bestselling, doom-saying book The Population Bomb; since then, neo-Malthusian rumblings of imminent disaster have been a continual refrain in certain sections of the environmental movement – fears that were recently given voice on David Attenborough’s documentary Life on our Planet.
At the time the Ehrlichs were publishing their dark prophecies, the world was at its peak of population growth, which at that point was increasing at a rate of 2.1% a year. Since then, the global population has ballooned from 3.5 billion to 7.67 billion.
