Ethanol, a costly plan of the federal government:
CBO estimates that the increased use of ethanol accounted for about 10 percent to 15 percent of the rise in food prices between April 2007 and April 2008.
In turn, increases in food prices will boost federal spending for mandatory nutrition programs such as the Supplemental Nutrition Assistance Program (SNAP, formerly known as Food Stamps) and the school lunch program by an estimated $600 million to $900 million in fiscal year 2009.
Oh, come on! Sure, it may cost us more, but we're saving the planet!
In the long run, if increases in the production of ethanol led to a large amount of forests or grasslands being converted into new cropland, those changes in land use could more than offset any reduction in greenhouse-gas emissions—because forests and grasslands naturally absorb more carbon from the atmosphere than cropland absorbs.
And some people still trust the government to save us from the scourge of global warming. Scary.
