  • On August 30, 1935, oceanographer Sylvia Earle was born in Gibbstown, New Jersey. Earle, nicknamed “Her Deepness,” has led more than 50 expeditions around the world, with more than 6,000 hours underwater. As an explorer-in-residence at the National Geographic Society, she is an advocate for underwater creatures and their ocean habitat. In recent years, Sylvia Earle has worked to create a network of marine protected areas throughout the world.

    Earle reminds listeners that protecting the ocean is protecting the Earth: “Ninety-seven percent of Earth’s water is ocean. No blue, no green. If you think the ocean isn’t important, imagine Earth without it.”

    Currently, less than one percent of the world’s oceans are protected.
