It’s time for the annual Global Population Speak Out. We all know that in order not to crash the planet we need to consume less energy and raw materials and we need to emit less pollutants. But it doesn’t seem to be generally known that nothing an affluent Westerner does can have anywhere near as beneficial an effect on the future environment as not having kids. Riding a bike to work, recycling milk cartons, turning off the outdoor lamp before you go to bed — all of those green efforts of yours will be swamped and obviated if you have that extra kid.
Think about it. If there were only a few million people on the planet, then we wouldn’t have to worry about consumption or pollution. The problem is partly our environmental footprint per capita, but more the sheer number of people on the planet.
So, as I once wrote, for a person to produce more than two children is unethical. If you want lots of kids, then adopt — preferably from an affluent country, as you only make things worse if you move people from cultures with a small environmental footprint to a land of big cars and hamburgers.
We need to give little girls worldwide a good education, because that makes them have fewer kids when they grow up. And we need to combat various religious organisations that sow doubt about the efficacy and moral acceptability of contraceptives.
The population will not continue to grow for ever, nor remain constant on a high figure for very long. Sooner or later the human population will come down. It’s up to us to decide if this should happen through contraception and a global single-child policy or through a catastrophic die-off.
