Rodale's LaSalle urges expansion of organic farming to mitigate impacts of warming

Could organic farming help to significantly reduce greenhouse gas emissions in the United States? During today's OnPoint, Timothy LaSalle, CEO of the Rodale Institute, discusses research conducted by Rodale that shows significant declines in greenhouse gas emissions when organic farming practices are used. LaSalle responds to critics who say organic farming is unsustainable and produces smaller crop yields. He discusses the impact rising food prices may have on the future of the organic farming industry and explains what, he believes, needs to be done legislatively to help promote organic farming.
