Biofuels for good: The emerging biofuels industry in the us could require as much land by 2050 as is currently farmed for food, said a report by a group of 22 international scientists in the October 3 issue of Science magazine. The scientists stated that the biofuels industry, if managed under a sound, science-based policy, could increase domestic energy security and mitigate greenhouse gas emissions. At present, the us lacks the standards to ensure that producing biofuels won't harm the soil, cause nitrogen fertilizer pollution and a decline in biodiversity as is the case with the grain-based biofuel cropping systems. The 2008 Farm Bill provides subsidies for growers of biofuels crops and for refiners who convert these crops into ethanol.
