Over 1500 college and high school campuses will take part in the largest teach-in in U.S. history at the end of the month. The “Focus the Nation” teach-in will create an open dialogue between students, civic leaders and policy makers on the issue of climate change. Students David Solheim of the University of Nebraska-Lincoln and Lacey Riddle of the University of Portland in Oregon tell host Bruce Gellerman about their schools’ plans for the big day.
