Sir David Attenborough: If we do not control population, the natural world will
This is, of course, true.
But what he doesn’t get is that we already know how population can and should be controlled. Get rich.
It’s a very simple point: as incomes pass through some quite low point (I’ve seen claims that it’s as low as $3,000 per capita) then fertility slumps and lo, we have solved the population problem.
So, if you’re a worrywart about population then you need to be arguing for the best and fastest method of getting incomes in general above that point (whatever it actually is).
No, it’s not availability of contraception (although that obviously helps at the margin, but it is at the margin, only 10% of the fertility fall), the education of women (that is an effect of the rise in income, not a cause), gender equality nor even of economic equality. It’s about the level of income. Thus it is the level of income that should be targeted.
And we also know what is the best method of getting income over that point. Capitalism red in tooth and claw along with free to freeish markets. That Industrial revolution stuff. Neoliberalism if you wish to call it that.
We can worry about all the social democracy stuff later, once the population part is solved. Assuming, of course, that you are one of those who think that population is the main problem to be faced.
Those who do worry about population and don’t support the neoliberal globalisation project are therefore being inconsistent, at the very least. Which happens to be most of those who worry about population in fact.
