Rob Green’s recent Wall Street Journal op-ed “The cause of higher grocery bills isn’t the drought. It’s the failed federal ethanol policy” fails to take into consideration a host of factors, other than demand for corn, that affect food prices.

In some cases, factors such as higher oil prices affect one or more of these underlying costs producing higher domestic and world food prices.
