I was inundated with preaching of the over crowed world as a kid (30 years ago), and that we can't grow enough food to feed people. Then I went along on the family vacation all the way through California on I-5 and fell asleep watching all the vineyards go by. Waking up some 4 hours later we were still passing vineyards. After that I will never listen to another crackpot about world hunger until people stop using some of the most fertile land in the world so they can let the fruit rot and get a little buzzed by drinking it. The U.S. alone could supply the world with more than enough food if it was properly farmed and rotated, but that's not what it's about. I helped fill a container with canned goods back in the 1980's to go to starving people in Ethiopia, only to find out that the government seized it and had it destroyed. They didn't want their people to have food because they might have enough energy to rise up and kill them.
