Pew Bertarelli Ocean Legacy

From the heat of the equator to the deep chills of the North and South poles, the ocean binds the planet together. Making up more than 70 percent of the Earth’s surface, it is home to nearly a quarter of the world’s known species, many of which still await discovery. But human activities are increasingly threatening its health.

Research shows that large, fully protected marine reserves are a key tool for addressing many challenges to ocean health. Reserves help conserve valuable biodiversity and protect traditional cultures closely linked to the sea.

In 2006, The Pew Charitable Trusts and several partners launched the Global Ocean Legacy project in an effort to establish the world’s first generation of great marine parks. In its 10 years of existence, Global Ocean Legacy helped to obtain commitments to safeguard more than 2.4 million square miles (6.3 million square kilometers) of ocean.

But even with these successes, less than 3 percent of the world’s ocean has strong protections. Recognizing that the International Union for Conservation of Nature recommends we need to protect 30 percent of our oceans, based on the best-available science, Pew and the Bertarelli Foundation have joined forces in a new partnership with the goal of increasing the number of fully protected parks in the sea from nine to 15 by 2022.

  • See the World's Newest Marine Park in the Pacific Ocean

    For the health of the ocean and all who depend on it, this is big news: Last week, Mexico became the latest nation to create a large, fully protected marine reserve. The Revillagigedo Archipelago National Park, the country’s largest marine protected area, is larger than the state of New York and protects 57,176 square miles (148,087 square kilometers) from fishing and other extractive...

  • Revillagigedo Archipelago National Park

    Mexico’s Revillagigedo Archipelago National Park, located 400 kilometers (250 miles) south of the Baja California peninsula in the Pacific Ocean, is now North America’s largest fully protected marine reserve. The park’s waters are home to 366 species of fish, including 26 found nowhere else. They also serve as an important gathering place for large migratory species such as... Read More

  • Revillagigedo Archipelago

    The Revillagigedo Archipelago sits off Mexico’s Pacific coast, about 800 kilometers (500 miles) west of the city of Manzanillo and 400 kilometers (250 miles) south of Cabo San Lucas. With its rich ecological and geological landscape, the volcanic island chain was named a UNESCO World Heritage site in 2016. Read More
