Granddaughter of Jacques-Yves and daughter of Philippe, Alexandra Cousteau didn’t stray far from the family mission. A tireless crusader determined protect the planet’s oceans, Alexandra (who prefers to be referred to by her first name out of respect for her grandfather's work) founded the Blue Legacy initiative in 2008 to “help shape society’s dialogue to include water as one of the defining issues of our century and to inspire people to take action on critical water issues in meaningful ways.” As a National Geographic Emerging Explorer and United Nations Earth Trustee, Cousteau is not only a friend of Mother Nature but part of the Mother Nature Network as well — she sits on MNN’s board of directors.
