Detailed explanation-1: -They can seep through the soil and find their way into rivers. The pollution described above can easily end up in sea water simply by being transported there by rivers. River estuaries and coastal waters are particularly affected. In addition, a lot of waste is deliberately dumped in the open sea.
Detailed explanation-2: -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.
Detailed explanation-3: -As excess debris in the ocean slowly degrades over many years it uses oxygen to do so, resulting in less 02 in the ocean. Low levels of oxygen in the ocean lead to the death of ocean animals such as penguins, dolphins, whales and sharks. Excess nitrogen and phosphorus in seawater also cause oxygen depletion.
