“Why is it that scuba divers and surfers are some of the strongest advocates of ocean conservation? Because they've spent time in and around the ocean, and they've personally seen the beauty, the fragility, and even the degradation of our planet's blue heart.”

American marine biologist and oceanographer

Sylvia Earle is an American marine biologist, oceanographer, explorer, writer, and lecturer. Born in 1935, she is known for her work in ocean science and for helping bring public attention to the sea. She has served as a National Geographic Explorer at Large since 1998. Earle was the first chief scientist of the U.S. National Oceanic and Atmospheric Administration, and Time named her its first Hero for the Planet in 1998. Her writing and talks often return to the ocean and the need to understand and protect it.
