For our 50th episode we talk with Dr. Craig Downs, the Hawaiian scientist who discovered and popularized the threat petrochemical-based sunscreens and other skin care products pose to coral reefs, fish and additional marine wildlife. Along with the role of Oreo cookies in his discovery, he talks about the ‘zombification' of reefs and fish exposed to chemicals in sunscreens, what’s being done to address the issue and how you can protect yourself from the sun without killing the Ocean.

Rising Tide, the Ocean Podcast is co-hosted by Blue Frontier's David Helvarg and the Inland Ocean Coalition's Vicki Nichols-Goldstein. This podcast aims to give you information, inspiration and motivation (along with a few laughs) to help understand our ocean world and make it better. The ocean is rising, and so are we!
