Water pollution why there is trash in the ocean

The ocean provides so much for us — food, medicine and much of the oxygen we breathe. Today, the ocean is facing grave threats from pollutants that enter the ocean and not only harm marine life but also directly impact humans. You have the power to turn the tide and take everyday actions that will help prevent pollutants and trash from reaching our global ocean.

Home Ocean Facts What is the biggest source of pollution in the ocean?

What is the biggest source of pollution in the ocean? Most ocean pollution begins on land When large tracts of land are plowed, the exposed soil can erode during rainstorms.

Much of this runoff flows to the sea, carrying with it agricultural fertilizers and pesticides. Eighty percent of pollution to the marine environment comes from the land.

One of the biggest sources is called nonpoint source pollution, which occurs as a result of runoff. Nonpoint source pollution includes many small sources, like septic tanks, cars, trucks, and boats, plus larger sources, such as farms, ranches, and forest areas.

Millions of motor vehicle engines drop small amounts of oil each day onto roads and parking lots. Much of this, too, makes its way to the sea. Some water pollution actually starts as air pollution, which settles into waterways and oceans.

Dirt can be a pollutant. Top soil or silt from fields or construction sites can run off into waterways, harming fish and wildlife habitats.

Nonpoint source pollution can make river and ocean water unsafe for humans and wildlife.

In some areas, this pollution is so bad that it causes beaches to be closed after rainstorms. More than one-third of the shellfish-growing waters of the United States are adversely affected by coastal pollution.

Correcting the harmful effects of nonpoint source pollution is costly. Each year, millions of dollars are spent to restore and protect areas damaged or endangered by nonpoint source pollutants.

NOAA works with the U. Environmental Protection Agency, Department of Agriculture, and other federal and state agencies to develop ways to control nonpoint source pollution. These agencies work together to monitor, assess, and limit nonpoint source pollution that may result naturally and by human actions.

When nonpoint source pollution does cause problems, NOAA scientists help track down the exact causes and find solutions.Pollution of Streams by Garbage and Trash Regardless of source or type, trash is a form of water pollution. Ironically, in some circumstances, some discarded items (e.g., tires * See "Pollution of the Ocean by Plastic and Trash" for a photograph of a bird en- shrouded by a piece of plastic.

Sewage Land runoff is another source of pollution in the ocean. This occurs when water infiltrates the soil to its maximum extent and the excess water from rain, flooding or melting flows over the land and into the ocean. The Clean Water goal is unusual because its four components--Trash Pollution, Nutrient Pollution, Chemical Pollution and Pathogen Pollution--indicate both Status and Pressure.

Low levels of those factors produce a high goal score, but high levels produce a .

(An excellent reason why we should all reduce plastic pollution, no matter where we live.) Oil from boats, airplanes, cars, trucks, and even lawn mowers is also swimming in ocean waters.
