David Lang is a drone expert whose work takes him into the deepest ocean waters of the world. He encourages us to fight to protect our oceans -- something we are all capable of doing collectively. This talk was filmed at TEDxBerkeley. All TEDx events are organized independently by volunteers in the spirit of TED's mission of ideas worth spreading.
