Dead Zones: Do More Biofuels Mean More Dead Fish?

That's a conclusion of a new scientific paper that looks at what it would take to produce the amount of ethanol required by the federal government in coming years. To hit the 2015 ethanol mandate, a lot of land currently set aside in conservation programs and other land used for soybean cultivation would need to be converted to corn. Growing all that corn means more fertilizer, which will feed into the Mississippi River and end up in the Gulf of Mexico. http://blogs.wsj.com/environmentalcapital/2009/04/03/dead-zones-do-more-biofuels-mean-more-dead-fish/
