In 2010, Sylvia Earle formed Mission Blue with the goal of protecting the Ocean aka Hope Spots. Some Hope Spots are already formally protected, while others still need defined protection. About 12% of the land around the world is now under some form of protection (as national parks, world heritage sites, monuments, etc.), while less than 4% of the ocean is protected in any way. Mission Blue is committed to changing this. Networks of marine protected areas maintain healthy biodiversity, provide a carbon sink, generate life-giving oxygen, preserve critical habitat and allow low-impact activities like ecotourism to thrive.
