Here is something all right-thinking liberals can agree on. Saving the planet is good;
manipulating humanity through eugenics is bad. The trouble is that these two ethical opposites come together when we talk about population control as a means of protecting the environment.
Most of us breed. And those of us who do have one ecological footprint in common: our offspring. Me included. So all greens have to ask: is having babies bad for the planet?
Fair enough. But there is another question that I find increasingly being asked. Should we be trying to stop others having babies, especially people in poor countries with fast-growing populations?
I must say I thought this kind of illiberal thinking had been banished from the environmental movement. But it keeps seeping back. When I give public talks on climate change, I am often asked if all the efforts in the rich world won't be wiped out by rising populations in the poor world.
Isn't overpopulation more dangerous than overconsumption? I say no. But the unpalatable truth is that a lot of environmental thinking over the past half century has been underpinned by an unhealthy preoccupation with the breeding propensity of Asians and Africans.
They were, it was often held, polluting the human gene pool as well as the planet. Such thinking was not fringe: it involved some of the great names of the environment movement.
So the American academic
Garrett Hardin said in his classic and still-revered environment text
Tragedy of the Commons in 1968, "Freedom to breed will bring ruin to all." It must be "relinquished to preserve and nurture other and more precious freedoms." Lest we have any doubt who should do the relinquishing, he wrote elsewhere about how college students should have more children than those with low IQs.
Or take
Paul Ehrlich, author of
The Population Bomb from the same era. That book said the world could no longer feed itself and called for population control "by compulsion if voluntary methods fail."
Meanwhile the British book
Blueprint for Survival, published by
The Ecologist magazine, sided with the demagogue-of-the-day Enoch Powell in calling for "an end to immigration". Far from being ostracised as a right-wing tract, its recipe was supported by
Friends of the Earth and Peter Scott, the TV wildlife king and founder of the
World Wildlife Fund.
And this is not ancient history. Only recently, US groups opposed to all migration tried to get their policies adopted by the blue-chip environment group, the
Sierra Club. To many they sounded like a fringe group. Actually they were an echo of the earlier mainstream.
And the echo is becoming louder.
We hear it in the climate change debate. No matter that the average European or North American has carbon emissions 10 times greater than the average Indian or African, somehow it is those pesky breeding foreigners who are really to blame.
And now food shortages are growing and we will get more. Ehrlich, we are bound to be told, was right after all. You have been warned: green fascism could soon be on the march.
