The ocean covers nearly three-fourths of the globe and is home to nearly a quarter of the world’s known species, with countless yet to be discovered. 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 ocean plays an essential role in sustaining life on our planet, but human activities are increasingly threatening its 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.

Caring for the environment has long been an important part of Palau’s culture.

Establishment of the Palau National Marine Sanctuary would create a modern-day bul to safeguard this ocean life for future generations. Encompassing some 500,000 square kilometers (193,000 square miles), the sanctuary would constitute one of the largest fully protected areas of ocean in the world. Read More
