TEDxOilSpill - Sylvia Earle - By Killing the Ocean, We Kill Ourselves 

Sylvia Earle, called "Living Legend" by the Library of Congress and "Hero for the Planet" by Time, is an oceanographer, explorer, author and lecturer with a deep commitment to research through personal exploration. Earle's work has been at the frontier of deep ocean exploration for four decades. Earle has led more than 50 expeditions worldwide involving more than 6,000 hours underwater.
In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
