Oil leakage Oil leakage is the primary cause of sea pollution. It occurs as a result of the leakage of liquid hydrocarbons into the environment as a result of human activity, and oil factories often pollute the sea. The problem lies in the uncontrollability of oil leakage from factories. Almost one tonne of oil per million of oil transferred. An example was the incident in January 1993; the oil tanker struck a tunnel near Scotland’s Shetland Islands in the UK, The sea As ships ship oil into the sea to contribute to the problem of pollution. The increase in the number of ships used in trade and in seaports makes the pollution problem more dangerous, and the leakage of chemicals carried by some ships into the sea leads to pollution. [1] Chemical fertilizers Chemical fertilizers and pesticides are contaminants that affect the seas and the oceans. These fertilizers contain nitrogen-rich substances that farmers add to their land, which eventually pour into streams, rivers, and local groundwater, and then seep into estuaries, bays, H These nutrients promote the production of large amounts of algae, which consume oxygen in water, leaving areas with little or no marine life. Scientists have counted nearly 400 free zones around the world. [2] Solid Waste There Many of the solid pollutants of ocean water such as plastic bags, balloons, glass containers, shoes and packaging materials. If they are not disposed of properly, they will end up in the sea, plastic bags decompose very slowly, accumulate in huge amounts in the seas, Marine organisms eat it Food, causing her health problems; stomach and as close respiratory passages, are examples of these objects: whales, dolphins, seals, turtles, and solid contaminants also lead to pollution of beaches and other coastal habitats as well as pollution of the seas.
