Today we celebrate 50 years of the National Marine Sanctuaries System! On October 23, 1972 the United States launched a new era of ocean conservation with the enactment of the National Marine Sanctuaries Act. To protect nature, fight climate change, and provide equitable access to our amazing #ocean and #GreatLakes, we must designate new sanctuaries and commit more resources to their protection.
