In excitement to go green, many things may happen. Here is a case when pigs may get starved because of biofuels coming out of corn.

Greg Boerboom raises 37,000 pigs a year on his farm in Marshall, Minn. Those hogs eat a lot of corn-10 bushels each from weaning to sale. In past years he has bought feed for about $2 a bushel. But since late summer, average corn prices have leapt to nearly $4 a bushel. To reduce feed costs, he sells his pigs before they reach the normal 275 pounds, and keeps them warmer so they don’t devour more food fighting off the cold.

In the U.S., last year’s harvest was 10.5 billion bushels, the third-largest crop ever. But instead of going into the maws of pigs or cattle or people, an increasing slice of that supply is being transformed into fuel for cars. The roughly 5 billion gallons of ethanol made in 2006 by 112 U.S. plants consumed nearly one-fifth of the corn crop. If all the scores of factories under construction or planned go into operation, fuel will gobble up no less than half of the entire corn harvest by 2008.

Corn is caught in a tug-of-war between ethanol plants and food, one of the first signs of a coming agricultural transformation and a global economic shift. Ever since our ancestors in the Fertile Crescent first figured out how to grow grains, crops have been used mainly to feed people and livestock. But now that’s changing in response to the high price of oil, the cost in lives and dollars of ensuring a supply of petroleum imports, and limits on climate-warming emissions of fossil fuels. Farms are energy’s great green hope.

Will it happen the same way for sweet loving Indians, when a good proportion of sugarcane juice is used to produce ethanol in our sugar mills?
