How To Make Earth's Population Sustainable?

[ZenitYerkes]

The problem with overpopulation is not the people, it's their mouths. Think on how many acres of harvesting zones you need to feed a city.

We can keep living the way we do because there are poor countries that don't take the same resources as us, because if everybody had the same life standards as we have, we would be having now a nuclear war for the last clean water or food remaining on Earth.

And please, don't take it with socialism or any other ideology. Ideas don't kill. People who want to take all the power yes.
