Obama expands Papahānaumokuākea to create the world’s largest marine protected area
Papahānaumokuākea became the largest marine protected area on Earth in 2016, when President Obama expanded the Hawaiian ocean sanctuary to 582,578 square miles — more than four times its original size. The reserve shelters over 7,000 species, including Hawaiian monk seals and black coral, in some of the most intact reefs in U.S. waters.
