Understanding how we affect the ocean can be a challenge since most of what happens lies beneath the surface. In this episode, we travel to Charleston, South Carolina where locals have united to protect their coast from seismic blasting and oil exploration. We meet the self-professed "coral nerd" and a filmmaker of the "Chasing Coral" documentary, and the intrepid entrepreneurs of 4Ocean, whose passion for fishing, surfing, and diving inspired an ocean cleanup company in south Florida.
