Oil pollution in Gulf of Mexico An Oil Slick from a Satellite This water is generally returned to the sea at temperatures 11 to C F , which is higher than it was initially.

Higher temperatures can lead to premature spawning, fish migration, lack of oxygen or death of marine life. By this, radionuclide enter into the food chain of marine water.

Spoils from dredging or mining of offshore minerals are deposited within a few miles of shore, where the potential impact is the greatest. Consequently, they often contain objectionable amounts of hazardous chemicals, pathogens, or oil and may exert a high oxygen demand on the surrounding environment.

That occurring at the dredging site, and 2. That occurring at the dredge spoils disposal area. Hence it is necessary to aware about the marine pollution, and to protect the marine water from the pollutants. So, necessary to prevent and control this pollution.

The planet keeps nudging us with increasingly extreme droughts, reminding us that water is life. It is an essential resource upon which all living beings depend and it is crucial to all social and economic development, as well as energy production and adaptation to climate change. Nevertheless, we are now facing a gigantic challenge. How do we stop contaminating our rivers, seas, oceans, canals, lakes and reservoirs? Water pollution is endangering the health of millions of people around the world. The waters of the River Ganges flow clear and clean through the Indian city of Rishikesh at the gateway to the Himalayas.

Oceans, which account for 70 percent of the surface of our planet, play a pivotal role in the health of our planet and those who inhabit it. Unfortunately, our oceans are polluted. According to the National Oceanic and Atmospheric Administration , billions of pounds of trash and other pollutants enter our oceans every year. The monumental impacts of this are far-reaching. There are many causes of ocean pollution. Of all the facts, there is one constant: most pollution in our oceans begins on land and is caused by humans.

Marine Pollution

Oceans are the largest water bodies on the planet Earth. Ocean pollution , also known as marine pollution , is the spreading of harmful substances such as oil, plastic, industrial and agricultural waste and chemical particles into the ocean. Since oceans provide the home to a wide variety of marine animals and plants, it is the responsibility of every citizen to play his or her part in making these oceans clean so that marine species can thrive for a longer period of time. Mining for materials such as copper and gold is a major source of contamination in the ocean. For example, copper is a major source of pollutant s in the ocean and can interfere with the life cycles of numerous marine organisms and life.

Pollutants are dumped into the ocean. This waste affects the daily life of fish and other marine creatures. This lists the logos of programs or partners of NG Education which have provided or contributed the content on this page.

Ocean Pollution: Causes, Effects and Prevention

Pollution entering our oceans from both man-made and natural activities is affecting marine ecosystems throughout the world. Animals often eat these pollutants which, means humans will as well. Runoff from the land comes from both urban and agricultural areas.


Marine pollution is defined as the introduction of substances to the marine environment directly or indirectly by man resulting in adverse effects such as hazardous to human health, obstruction of marine activities and lowering the quality of sea water. Municipal waste and sewage from residences and hotels in coastal towns are directly discharged into sea. Pesticides and fertilizers from agriculture which are washed off by rain enter water courses and finally to sea. India is estimated to use 55, tons of pesticides annually and about 25 percent of it is carried to-ocean. Ship accidents and accidental spillage at sea can therefore be very damaging to the marine environment. Dry docking: All ships periodic dry docking servicing; cleaning the hulls etc. Pollution due to organic wastes: When O 2 concentration falls 1.
