Just remember that the current population of the earth could fit into an area the size of Texas - 35 people to an acre. That would leave the entire rest of the earth unpopulated. Our population could multiple many, many times before critical mass is reached. Would lifestyles have to change? Of course. But all any of us really needs is a warm place during the winter and food to eat. Those things come pretty cheaply - a sustainable forest and arable land.

Sounds like just the kind of place that everyone would be killing everyone else.

Hmmm... Does that acre have enough "fertility" to feed the 35 people living on it?

I seem to recall reading that feeding a family of four by subsistence farming takes more then two acres.
