I heard this on the news this morning and I gotta say I'm with Daniel Gross in asking why wouldn't increased demand for corn from both the ethanol and livestock industries lead American farmers to increase the amount of corn acreage in order to meet that demand?  Or are they saying in the short-term American farmers and imported corn are unable to meet skyrocketing corn demand which will cause some economic dislocation among livestock growers (smaller herds) and the meat-packing industry (one processing plant closed?) until things shake themselves out later?
