An international group of food scientists says countries should not use food crops to produce biofuels during a world food crisis.

Three scientists with the Consultative Group on International Agricultural Research say if nations stop turning corn into ethanol this year, it would cut 20 percent from the price of corn next year. Instead of using grains, the international group is calling on the U.S. and other countries to shift biofuels production to nonfood crops such as switchgrass.

President Bush, in a White House press conference, says it is in the nation's best interest that American farmers grow energy instead of relying on foreign oil.

Here to talk about the intersection of food, water and oil is USF professor Mark Stewart. Stewart is a hydrologist at the University of South Florida. He is a professor of geology and a faculty affiliate of the Kiran C Patel Center for Global Solutions. His current research interests include water resources and carbon sequestration.
