New Protected Ocean Area Is Bigger Than All U.S. National Parks Combined

August 25, 2016 - In the Northwestern Hawaiian Islands, President Barack Obama has created the largest protected area in the world. At 582,000 square miles (1,507,373 square kilometers), the Papahānaumokuākea Marine National Monument has now quadrupled in size, making it larger than all U.S. national parks combined.

While 15 percent of the Earth's land is protected, only 2 percent of the oceans are. The expansion of Papahānaumokuākea will help preserve more than 7,000 marine species, including the threatened sea turtle and the endangered Hawaiian monk seal.
