Sylvia Earle on Life Underwater

Dr. Sylvia Earle presents the amazing “liquid jungle” of the depths of the Sargasso Sea, where 90% of creatures use bioluminescence as communication tools. She then demonstrates the devastating effects of the 2010 Gulf oil spill on these habitats, and emphasizes the pivotal point we are at in making decisions that effect the future of the oceans on which all life depends.
