Support marine protected areas. More than 18,000 square miles of ocean and coastal waters, from Cape Cod to American Samoa, are protected by NOAA's National Marine Sanctuaries. Human activities, such as fishing, boating, nearshore construction and commercial underwater ventures, can adversely impact marine wildlife if we're not careful. Birds, marine mammals and fish can die by swallowing or becoming entangled in plastic. Fishing line can strangle marine animals.
Hooks can injure other mammals, as well as humans walking near the shoreline.
Be aware of what you leave behind. It destroys natural feeding habits. Volunteer with a sanctuary, reserve or nonprofit group that works to protect coastal and marine habitats. Work individually with others to help keep the ocean clean and protect vital habitats like wetlands. Treat the ocean with care.
