In a pre-Earth Day talk, famed oceanographer and explorer Sylvia Earle shares her journey as a participant in decades of unprecedented ocean discoveries and as a witness to devastating loss, and what actions now can reverse planetary decline. She is joined in conversation by Academy Award-winning actress and activist Laura Dern.

A National Geographic Explorer in Residence since 1998, former Chief Scientist for NOAA, Time Magazine’s first Hero for the Planet, and a Library of Congress Living Legend, Earle founded Deep Ocean Exploration and Research to develop submersible technologies and the nonprofit Mission Blue to develop a global network of over 140 “Hope Spots” and marine protected areas.

Earle has authored a half dozen books and over 200 publications, lectured in over 80 countries, and led over 100 marine expeditions. A trailblazer in the use of modern SCUBA gear and the development of deep-sea submersibles, Earle also held the world record for the deepest untethered dive.
