Just remember that the current population of the earth could fit into an area the size of Texas - 35 people to an acre.

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.

Hm...you might be right, although you can grow a phenomenal amount of food on two acres of land. If you have to throw in cattle, that would increase the amount of land needed for grazing, of course.

I did not intend to insinuate that 35 people per acres was sustainable - did not make that clear, though. Just making that point that the world is a very huge place, and the area that humans populate is practically miniscule.
