I've said for a while now that people who feel overpopulation is a problem should show some dedication to the cause and blow their own brains out.
We destroy tons of good, edible food every hour of every day. We fill our landfills with cheap disposable crap instead of building things to last. Spoiled, overfed assholes sit on top of resources and refuse to let the rest of us at them so they can squeeze more money out of us.
Production and our planet's ability to sustain it aren't the real problems, here.
The biggest problem with resource allocation is the absence of infrastructure, not the total lack of resources. We have enough food to feed everyone on the planet; the problem is physically transporting it. It doesn't matter if Iowa produces enough corn to feed the world ten times over. Getting that corn to the horn of African does.
