GMO's have generally been regarded as "frankenfoods" and portrayed in the media as environmentally dangerous. Some scientists, however, say many fears have no basis and are proven to be unfounded. This hour, we speak with James McWilliams, the author of "Just Food: Where Locavores Get it Wrong and How We Can Truly Eat Responsibly" about his argument in favor of GMO's and how he thinks they could actually benefit the environment. Are our fears in "frankenfoods" unfounded? Should GMO's be clearly labeled? We also speak with Jeffrey Smith, author of "Genetic Roulette: The Documented Health Risks of Genetically Engineered Foods" to hear the other side of the debate.
