All writing in italics come from the November 28th Wall Street Journal article that Duns' link pulls up. There is more in there, but I thought this might be of most interest.
Last month, an outside expert advising the United Nations on the "right to food" labeled the use of food crops to make biofuels "a crime against humanity," although the U.N. Food and Agriculture Organization later disowned the remark as "regrettable."
The fortunes of many U.S. farmers, farm towns and ethanol companies are tied to corn-based ethanol, of which America is the largest producer.
Ethanol's problems have much to do with its past success. As profits and production soared in 2005 and 2006, so did the price of corn, gradually angering livestock farmers who need it for feed. They allied with food companies also stung by higher grain prices, and with oil companies that have long loathed subsidies for ethanol production.
In the past, livestock farmers supported ethanol because it was good for the overall farm economy. But now they began to complain that the higher corn price cut sharply into their profits. A meat-producer trade group called the American Meat Institute took a stand against federal support for biofuels last December, joined soon after by the National Turkey Federation and the National Cattlemen's Beef Association.
Opponents of ethanol also have hammered on an Agriculture Department projection that by 2010, less than 8% of the U.S. gasoline supply will come from corn-based ethanol -- and 30% of the corn crop will be used to make it. That suggests to some that the tradeoff between food and fuel is unbalanced.
Mr. Dinneen says arguments about ethanol driving up food costs are overblown, in part because corn farmers will produce so much grain that corn prices will ease. But even though U.S. farmers this year planted their biggest crop since World War II, prices have stayed well above $3 a bushel, thanks to rising demand in developing countries and poor weather in some grain-growing nations. The price is expected to stay well above $3 next year as farmers shift some land from corn to two other crops whose prices have risen sharply, wheat and soybeans.
