Sylvia Earle
"With knowing comes caring - With caring there is HOPE."
Sylvia, Glamour's "Explorer" of the year, is a legendary oceanographer who has discovered tens of thousands of species while embarking on over 100 explorations. Sylvia also stands up against over-fishing and pollution. Her foundation, Mission Blue, aims to protect the ocean, because, as Sylvia tells Glamour, the ocean "is the heart of our planet that keeps us alive."
