Conservationist Jeff Corwin on The National Defense

We welcome the host of “Wildlife Nation” and CBS’ “Extraordinary World,” Emmy-Award-winning conservationist Jeff Corwin, to the show.  Jeff has a new project, weekdays on ABC, “Wildlife Nation: Expedition Florida,” where he closely looks at the state of Florida, the trouble it is in, and what people can do to protect the Everglades and our biome.
