LA’s dirty air; Lovell Health House

Los Angeles-Long Beach has once again been cited the nation’s capital for dirty air, just as LA Mayor Eric Garcetti has made cleaning the air a central plank of his green new deal. We'll look at why the Southland’s air is dirty despite cleaner cars, and why automating the ports may not be the solution. And a classic modernist house is in distress and may be looking for a buyer. We tour the Lovell Health House with the owners and preservationists eager to restore it.
