Food for Fuel: An 'answer' for world hunger & high prices

It seems the new American way involves a process that is not just from farm to food, but from farm to fuel. In the name of a cleaner environment ethanol has, over the years, become very political, being blamed for everything from the power of the state of Iowa to world hunger.

It's growth has been largely due to a policy by the U.S. government- a federal subsidy paid to oil companies to incentivize them to use corn ethanol in their gasoline that is then sold to consumers at gas stations across the country. It lasted 33 years and cost more than 20 billion dollars.
