Biotech may come to the rescue when it comes to meeting future demand for corn needed for both food and ethanol. According to a study released by the National Center for Food and Agricultural Policy, U.S. farmers gained an additional 8.3 billion pounds of yield in 2005 due to biotech crops, including an extra 7.6 billion pounds of corn. This represents a 29 percent increase over 2004's harvest. The report notes that plant biotechnology boosted corn production by 39 billion pounds since it was introduced in the late 90s. That represents 1.9 billion gallons of ethanol.
