Garbage can end up in oceans because of improper disposal. Garbage works its way into the sewer system and then eventually out to standing water. "The first international agreement on direct dumping into the oceans—the 1972 London Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter—focused on substances harmful to humans or sea life. In 1987, the U.S. Congress passed the Marine Plastic Pollution Research and Control Act (MPPRCA). About 20% of the MSW in oceans comes from ocean shipping. The MARPOL Convention (originated in 1973) is the main international convention for the prevention of pollution from ships."
