John and Mike speak with Matt Petersen, the President and CEO of Global Green USA, a national environmental nonprofit working toward a sustainable future. With the support of both political and entertainment communities, Global Green USA works on project such as providing affordable housing, developing green schools with more positive learning environments for students and rebuilding New Orleans in the wake of Katrina’s devastation. Matt discusses new environmental challenges and green solutions, and how stars such as Leonardo DiCaprio, Brad Pitt and Jake Gyllenhaal are taking time away from the silver screen to become green all-stars.
