If you look at the way nature works, a species needs a predator to survive over long periods. Otherwise, since there's nothing holding them back then they can overpopulate the entire area, deplete it from its food and resources, and then slowly die off as there's nothing left to feed from.

From a weird, fucked up perspective, I just had a thought for a moment which made me think that way about humanity, except on a supermassive scale. We don't have any natural predators that seriously hold us back from overpopulation, except for other humans. Could war be part of our natural life cycle which prevents us from overpopulating the planet?
