This over population hysteria has been going on since the hippie generation. The world is nowhere near stressing on food supplies. Any problem with food supply today is political. Its not about supply. ITs about inflation. Gasohol has raised the price of food. Printing too much money has inflated the value of what the poor in Arab countries could make. The Arab spring wasnt about politics; it was about the sudden 15% increase in food prices. Probably every starvation in modern times was more do to economic collapse, politics or war than weather or crop failure.
I agree about the gasahol issue, but paying farmers to not plant and harvest crops is stupid too. Farmers know best when to plant and what to plant. Let them do it.
