Marine debris is the term for any manufactured item that ends up as trash in our ocean, lakes, or inland waterways, More than an eyesore, trash in the ocean is one of the world's pervasive problem. It sickens and kills thousands of marine animals and birds. It is also undermines economies based on tourism and fisheries. All kinds of trash, from cigarette butts and fishing line to tires and large household appliances, accumulate on beaches and beneath the water surface. All of it shares a common origin. At a critical point decision point, someone, somewhere mishandled it, either thoughtlessly or deliberately. Where does all the trash in the ocean originate?  Knowing the answer to this question leads to better management plans and policies to stop it at the source. During International Coastal Cleanup day, not only do we pick up trash but also record information about it using the Ocean Trash Data Form.
