Killer Garbage in Our Oceans

Marine trash poses a great danger to sea life. In Papahānaumokuākea, a marine national monument established with the intent of protecting the last few pristine coral reefs and pacific island habitats in our national waters, garbage chokes out natural life in the reefs and shore. Of the 50 tons of ocean litter removed on the latest cruise, approximately half was composed of broken fishing gear and plastic collected on and around Midway Atoll National Wildlife Refuge.

It is important to remember that, while the consequences of the Japanese tsunami have brought this issue to national attention, marine trash is neither a new nor a transient problem. By the time a massive, 70 foot dock washed ashore in Oregon, ocean currents had already concentrated trash in the oceans into massive “garbage patches.” The largest of these, the Great Pacific Garbage Patch, is conservatively estimated to be bigger than the state of Texas. What is it composed of? Plastics and derelict fishing gear, mostly, but also chemical pollutants and other miscellaneous trash. This debris circulates through the ocean gyres until it is broken down into microscopic parts or driven back ashore.
As Koyanagi reminded the nation, “[M]arine debris is an everyday problem, especially right here in the Pacific.” Two bills currently moving through Congress, the Marine Debris Reauthorization Amendments of 2011 (H.R. 1171) in the House and the Trash Free Seas Act of 2011 (S. 1119) in the Senate, would provide NOAA the funding and resources necessary to continue its Marine Debris Prevention and Removal Program. These bipartisan bills are vital to NOAA’s efforts to address and manage the threat of ocean litter to our coastal communities and wildlife.
