Overpopulation?

Optimum population of humans: Ideally, how many people can, or should, the Earth support?

It can seem like the human population can grow forever, but analysis makes it clear growth must stop eventually. The question becomes at what level should it stop?

Do we go for the maximum possible people before everything collapses, even if average living standards could be far better with a smaller population? Is it like a chicken farm in an egg farm, where having less chickens is seen as preferable if it means chickens get better living conditions? What population strikes the right balance for humans?

Overpopulation: starvation is the last symptom.
