The U.S. Coast Guard Auxiliary reminds everyone that marine debris are everyone's concern and everyone's problem. Debris generally originates, from two distinct sources, the sea (and inland waterways) and land. Ocean/inland waterways-based sources include boats and ships including the smallest sailboat to the largest container ship, along with offshore rigs and drilling platforms. Land-based sources include, sewer overflows and storm drains, landfills, manufacturing and sewage treatment plants and beachgoers. About 80% of debris originates onshore with 20% coming from offshore sources. Some marine debris persist in marine environments for a very long time – Mylar balloons (centuries), derelict fishing gear (centuries), plastic bags (centuries), cigarette butts (2 – 10 years), monofilament line (600 years), plastic bottles (450 years), 6-pack holder (400 years), aluminum cans (200 – 500 years), and Styrofoam buoy (80 years).
