Robert Redford: Business Warming Up To Environment

In a Web-exclusive interview, actor, director, and environmentalist Robert Redford talks to NOW's David Brancaccio about why he thinks "change is in the air" as businesses find value in going green. Redford says environmental issues are gaining traction as social entrepreneurs discover "there [is] money to be made by doing good." An executive producer of the new documentary "The Unforeseen," Redford also talks to NOW about why he thinks global warming will be "huge" in the 2008 presidential election.
