Legendary oceanographer and marine biologist Sylvia Earle, often called "Her Deepness," is a National Geographic Explorer-in-Residence and former chief scientist at the US National Oceanic and Atmospheric Administration (NOAA). She's a fierce champion for ocean conservation in general and marine protected areas in particular. "The ocean has given us everything, life itself, now it's time to give back," she says in this wide ranging conversation with Mongabay. Despite difficult trends, she also reports being 'seriously optimistic.'
