The Scientific American reports that roughly 40 percent of today’s corn crop is used for ethanol made from corn, which is added to gasoline. That is more than the second largest use of corn, as feed for cattle, pigs and chickens, which consumes 36 percent of the annual corn crop. Is it wise to burn food for fuel, more than for feeding a hungry world?

Using so much of the corn crop for fuel for cars and trucks rather than for food has already caused world prices for corn to rise sharply. That is not noticed in rich countries. But it has caused food riots in poor, third world countries, where poor families suffer hunger as a result.

This is particularly outdated in a world flooded by oil and natural gas, due to the effects of modern fracking. That flood has already caused world prices of oil and gas to sink, actually to the point of reducing such traditional energy production.

Contributing to these perverse effects is the U.S. Renewable Fuel Standard (RFS). That policy requires all transportation fuels sold in the U.S. to contain a minimum level of renewable fuels, such as ethanol.
