The Chinese government claims the one-child policy has saved China and the world from 400 million additional people to feed, educate, transport, and power in an ecologically fragile world, a claim that resonates with international concerns for the planet’s future. This claim is greatly exaggerated, if not entirely bogus. Yet even if China’s population is somewhat lower today or will level off in the future at a slightly lower level due to this policy, this reduction must be judged against the high costs it has exacted from the generations that have borne the brunt of the policy and those who will live with its long-term negative consequences. Before accepting “population control” as part of the mix of policies intended to combat climate change and ecological destruction, we will do well to look long and hard at those consequences as a cautionary tale of what happens at the extremes.
