CWR co-hosts Bill Baue and Francesca Rheannon speak with Gary Hirshberg, CEO of organic yogurt maker Stonyfield Farm, and author of Stirring It Up: How to Make Money and Save the World. Hirshberg believes that business is a necessary force for creating a sustainable economy and society, as outlined in his recent book Stirring It Up. Yet he admits that business is a primary cause of our current unsustainable economy, a seeming contradiction that he explains in our conversation.
