In this episode David talks with renowned marine scientist Dr. Nancy Knowlton about her background, her work on coral reefs and her launching of a multi-disciplinary, solution oriented marine program at Scripps.  She also talks about her expanding work on ocean and earth optimism at the Smithsonian Museum of Natural History and why that’s not an oxymoron but a starting point.  This and more on restoration and realism makes for an engaging and, dare we say, hopeful segment.
