Marine debris can enter the ocean in a variety of ways. From land, trash may be carried to the ocean in rivers or storm and sewage drains, swept from the beach by waves and surf, or blown offshore by winds, especially during heavy storms.he most common way to measure floating plastic in the ocean is to collect it using very fine-meshed nets towed at the ocean surface from a ship. At SEA we have been measuring plastic debris using this method for more than 25 years.
The garbage gets into the oceans when people litter. Some boaters and beachgoers throw their trash directly into the water. Trash also gets thrown into rivers that flow into oceans. In fact, most ocean trash comes from rivers.In Australia, for example, 80 percent of ocean trash comes from waterways far from the sea. The biggest concern about ocean trash is that most of it is plastic.In some places, nearly 80 percent of the ocean trash that has been collected is made of plastic, according to the UN report. Plastic can take up to 1,000 years to biodegrade, or break down into smaller parts, once it's thrown away.he biggest concern about ocean trash is that most of it is plastic.
