Overpopulation

This is a pretty good speech on how thew elites create a fear of overpopulation:

That being said, overpopulation is not an insignificant concern unless some free energy source is invented or allowed to be released. It's not that the planet can't sustain 10 billion humans, but the issue is what kind of quality of life would they have-- or the vast majority anyway. The video makes a good point about inequality, and there is going to be massive inequality no matter what the population.
