You are correct about Mr. Malthus, although remember he didn't do too badly with the statistics available at the time, circa 1800. Increase in food production simply isn't really linear, although the numbers available at the time led him to conclude that it was.
We do have starvation in the world, but it is very seldom the direct result of population growth outstripping food production. I can think of a couple of examples where disease was the culprit (the post-Plague famines of the mid-14th century and the Irish Potato Famine) but in modern times it is nearly always a consequence of politics. It isn't that human beings are helpless, it's that we're stupid.
Hahaha. Amen to that. Some more than others but a valid point. But over population in this context I presented as merely a variable as in: What if every sexually capable adult were straight and reproducing. I think we would be in trouble.....
