The Clean Air Act was most recently amended in 1990, with overwhelming bipartisan support. Is that kind of sweeping environmental policy possible today?
Host Ben Kieffer wraps up our summer series, "Ripple Effects," with a look at environmental policy at the federal, state and local levels. Guests include U.S. Senator Charles Grassley, Iowa Secretary of Agriculture Bill Northey, Des Moines Mayor Frank Cownie, State Senator Rob Hogg and Monroe County Supervisor Dennis Ryan. They consider when government should intervene and how, and whether a carrot or stick approach is more effective in protecting the environment.
