The ocean covers nearly three-fourths of the globe and is home to nearly half of the world’s known species, with countless yet to be discovered. Producing almost half of the oxygen in the atmosphere, it also absorbs vast amounts of carbon dioxide.
The ocean helps support more than 250 million people who depend directly or indirectly on fishing for their livelihoods, and provides the main source of animal protein to more than 2.6 billion people. The oceans play an essential role in sustaining life on our planet, but human activities are increasingly threatening their health. Research shows that very large, fully protected marine reserves are key to rebuilding species abundance and diversity and protecting the overall health of the marine environment.
Global Ocean Legacy, a project of Pew and its partners, is working with local communities, governments and scientists around the world to protect and conserve some of our most important and unspoiled ocean environments.
Together we are establishing the world’s first generation of great marine parks by securing the designation of large, fully protected reserves. To date, our efforts have helped to double the amount of safeguarded ocean habitat worldwide.
