America's Troubled Relationship with its Police

Guest: Richard A. Clarke, leader of counterterrorism efforts for Presidents Bill Clinton and George W. Bush, Co-author of “Warnings: Finding Cassandras to Stop Catastrophes”

Guest: Elliott Campbell, PhD, Associate Professor of Environmental Engineering, UC Merced The “local food” movement has gone beyond a handful of hip, progressive towns to touch nearly every city in America. Farmer’s markets and locally-grown produce are fairly easy to find these days. But even the most devoted locavores have to get some of their diet from beyond the 50-mile radius generally considered the boundary of “local.”  If one day all Americans decided they wanted to eat only local food, would anybody starve? University of California-Merced’s Elliott Campbell analyzed food production and population trends across the country and found that, surprisingly, about 90 percent of the country could be fed by food grown nearby.

Guest: Lew Fulton, Co-Director at the Sustainable Transportation Energy Pathways Program, UC Davis Institute of Transportation Studies Driverless cars are the future, judging by the billions of dollars being invested in them, and electric cars are well on their way to American roads. It seems that combining the two movements would guarantee cleaner air and fewer traffic jams, but, according to an analysis by the Institute of Transportation Studies, the only way to get to that future is by adding a third piece to the puzzle—ride sharing.
