It’s kind like old Sam said, may god rest his irreverent soul;
“You know, we’ve been coming here giving you food for about 35 years now and we were driving through the desert, and we realized there wouldn’t BE world hunger if you people would live where the FOOD IS!
But it took a study to figure it out. Academia= Educated Idiots.
"We have deserts in our country, we just don't live in 'em, *******!" [kind of a weird joke for Sam, since he'd lived in LA already]
So basically people in the Neolithic period were able to figure this out in areas OTHER than Africa where they still haven’t figured it out. There are some who never learn.
