Coral reefs are important for the health of our oceans and planet. These reefs produce much of the oxygen that we breath, and provide a habitat for the fish we eat. Recently, there’s been a lot of reporting on how climate change is causing the widespread death of these ecosystems. Dave Vaughan is Executive Director of Mote's Elizabeth Moore International Center for Coral Reef Research & Restoration in Summerland Key, Florida.  On this episode of The Show About Science, Nate talks to Dr. Vaughan about his work to regenerate coral and repopulate the reefs in the Florida Keys.
