This episode of The Iowa Journal examines the debate over whether corn should be used for food or fuel. Corn-based ethanol has caused a worldwide uproar in recent months. Critics have blamed the renewable fuel for high food costs, growing gas prices, and starvation in developing countries. But the ethanol picture is not as simple as food versus fuel. In the studio to discuss these issues is Bruce Babcock, Director of the Center for Agriculture and Rural Development at Iowa State University. In this week’s Out and About segment, correspondent Dan Kaercher travels to Pocahontas. Radio Iowa's Kay Henderson talks with host Paul Yeager about the rally by Sen. Barack Obama in Des Moines earlier in the week. Henderson also discusses the veto of the farm bill. (27:46)
