BACKGROUND

Although marine pollution has a long history, significant international laws to counter it were not enacted until the twentieth century. Marine pollution was a concern during several UN, beginning in the 1950s. Most scientists believed that the oceans were so vast that they had unlimited ability to dilute, and thus render pollution harmless.

Marine pollution was a major area of discussion during the 1972 United Nations Conference on the Human Environment, held in Stockholm and then everything changed

Where does this pollution come from? Where does it go? Some of the debris ends up on our beaches, washed in with the waves and tides, some sinks, some is eaten by marine animals that mistake it for food, and some accumulates in ocean gyros. Other forms of pollution that impact the health of the ocean come from a single, known sources, such as oil spills, or from accumulation of many dispersed sources, such as fertilizer from our yards.

Sources

The majority of pollutants going into the ocean come from activities on land. Natural processes and human activities along the coastlines and far inland affect the health of our ocean. One of the biggest sources is called no npoint source pollution, which occurs as a result of runoff. Noncpoint source pollution includes many small sources, like septic tanks, cars, trucks, and boats, plus larger sources, such as farms, livestock ranches, and timber harvest areas. Pollution that comes from a single source, like an oil or chemical spill, is known as point source pollution. Often these events have large impacts, but fortunately, they occur less often. Discharge from faulty or damaged factories or water treatment systems is also considered point source pollution.

Challenges faced

Since Nepal is landlocked country we are not directly in contact with marine. so all the impact of the marine pollution should be searched via news portal or internet .Most of data images were from internet.
even though we are landlocked the solution to marine pollution and river pollution are similar.
the result shown by solution showed some good results before and after clean up
the big challenge will be to do it in large scale by every people in the earth.

built
So we acutally did recommend some solution and found some exciting ways to solve the problem
