"To avoid future global unrest, Bar-Yam says the U.S. government should reduce the ethanol mandate by at least half this year to help boost the world's food supply.
Bar-Yam admits its not an easy decision to make in the middle of an election year. Iowa, the largest ethanol-producer in the country, is also a swing state. Farmers there make more money as a result of the ethanol mandate than they would otherwise. But Bar-Yam says self-interest has no place in today's world.
"If we are concerned only about our own interests, we will suffer the consequences because our world is a connected world and we are all involved in the same system," he said."
