 Located 130 miles off Cape Cod, Massachusetts, the area spans more than 3 million acres and is part of the Biden administration's plan to conserve at least 30 percent of U.S. lands and waters by 2030. Keith Shannon with the U.S. Fish and Wildlife Service calls the monument a living laboratory of pristine ocean habitat. Dolphins, multiple whale species and sea turtles and seabirds. It's considered the Serengeti of the sea. There's so much wildlife out there.
