The Full Story
Early marine protection in the United States dates to 1935, when Fort Jefferson National Monument was established in the Dry Tortugas, covering surrounding waters. Although not a marine protected area in the modern sense, it marked an early step toward protecting coastal and marine environments. The modern concept of marine protected areas expanded in the second half of the 20th century as conservation became more formalized. Today, MPAs are a key tool for safeguarding reefs, fish populations, and ocean habitats.
