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.

Just six weeks after it started, 2015 already is shaping up to be a bad year for vessels fishing illegally—and a good moment for ocean life. Read More
Washington—The Pew Charitable Trusts launched groundbreaking technology today that will help authorities monitor, detect, and respond to illicit fishing activity across the world’s oceans. The development of Project Eyes on the Seas, as the system is known, furthers a long-term effort by Pew to dramatically reduce illegal or “pirate” fishing. Read More
Monitoring and enforcement of marine reserves can be challenging in remote parts of the world, where many of the last near-pristine waters are found. To help meet this challenge, The Pew Charitable Trusts has partnered with Satellite Applications Catapult, a U.K. government initiative created to help foster economic growth through the exploitation of space. Together, they have pioneered a system... Read More
