In the late 1960s a biologist named Paul Ehrlich insisted that the world’s rapid population growth was unsustainable. What could be done? Ehrlich proposed radical population control measures—including sterilization.
A new study concludes that strict fertility measures, such as a one-child policy, or even a mass catastrophe like a global plague or a third world war, would not have a significant effect on the human population trajectory this century.
