you have a good point. I usually try to see this in evolutionary terms. Though I guess the question is, did food shortage help us, or did we just survive in spite of it? I mean, people did only live for 30 or 40 years, I don't wanna model myself too closely on caveman diet
oh, goody, I can't wait.
due to drought? I dunno, I think it's gonna be due to just too many people. I mean, if everyone on earth had a diet as rich in meat as a typical US diet, all the earths land mass would have to be dedicated to growing food for the animals.
