She now heads Mission Blue, a nonprofit she launched in 2009. Its goal: the legal protection of 20 percent of our oceans by 2020. To that end, Earle teaches about what she calls “Hope Spots,” places critical to the health of oceans. She lobbies governments and citizens all over the world to protect these areas, from the algae-covered Sargasso Sea in the North Atlantic to the rocky shores of California’s Monterey Bay. In September, Earle stood alongside President Obama as he announced the quadrupling of Hawaii’s Papahānaumokuākea Marine National Monument, expanding it to a 583,000-square-mile “no-take” zone, off-limits to fishing and some commercial activities. Earle thanked Obama, not for herself, but “on behalf of all people and all life everywhere.” Then she gave him a picture of a fish that lives only there, which has no name yet, but will be named for him.
