Sylvia Alice Earle (born: Aug 30, 1935) is a marine biologist, aquanaut, author and speaker. She has been a Nat Geo explorer-in-residence since 1998. She was the first female chief scientist of the US National Oceanic and Atmospheric Administration. She was named the first Hero For The Planet in 1998 by Time Magazine. Her group, Ocean Elders, are fighting the fight as oceanic protectors.
Her Wikipedia Timeline:
I am in awe of her life. “We must take care of the ocean. We must take care of the natural world from the skies above to the depths below.” Could not agree more Ms. Earle.

I HIGHLY recommend the documentary on Netflix. And yes, expect a blog about it a little later down the road.
