Introduction
Oil pollution is one of the most significant form of the damage to the marine environment, and it is a serious global issue. It can bring huge bad effects to the environment, marine lives and even the human being. It happens during the process of oil exploitation, transportation, handling, processing and use, due to leakage and emissions of oil caused by pollution, mainly in the ocean (Zhao, 2010).
While the oil floats on the sea surface, it can spread and form oil film rapidly, and can be transported through diffusion, evaporation, dissolution, emulsification, photodegradation and biodegradation and absorption. Oil can be attached to the fish gills which will lead to suffocation; inhibit water birds spawning and hatching,

The oil runoff from the land is complex, it can hang around in the ocean and move between water and sediment, which will make it difficult to effectively track (Dell’Amore & Nunez, 2014).
(2) Land city sewage. The land city sewage is also a source of oil pollution to the ocean while countries all over the world will discharge the untreated or insufficiently treated water waste into the ocean that may contain pollution components.
(3) Transportation of ships and tankers. The oil pollution may also come from the operational discharges from ships, oil spill that caused by accidents such as the collision of oil tankers or hit the reef, and operating sewage, ship repair sewage and ballast water sewage (Li, Wang & Ha, 2014).
(4) Offshore oil exploration. During the offshore oil exploration, it can also contribute to the oil pollution including oil spill, oil remover, drilling mud, fuel, ballast water and oil production, etc., usually a mixture of petroleum hydrocarbons, heavy metals, synthetic organic matter and radioactive substances and other pollution components (Li, Wang & Ha, 2014).
(5) Oil extraction platform. Similar to the offshore oil exploration, the pollution may occur when the accidental oil spills and other operation
Ship operations and bilge cleanings release around 137 million gallons of water into the ocean a year. When it rains, hydrocarbons that are released from cars and industry settle from the air into the ocean releasing 92 million gallons of dangerous hydrocarbons into the marine environment. 37 million gallons of spilled oil in the ocean is due to major tanker accidents. One big spill, however, can affect not only sea life but also shore life for miles. Offshore drilling causes 15 million gallons of oil to be spilled into the ocean per year due to operational discharges and other spills. Although humans cause much of the oil pollution, natural seeping is also a large contributor. Natural seepage comes from the bottom of the ocean and also from sedimentary rocks that are gradually wearing away. Natural seeps allow 62 million gallons of oil to be released into the ocean per year. (Gradwohl) This roughly means that around 706 million gallons of oil are dumped into the ocean every single year, threatening the lives of fish and sea creatures and destroying the luscious marine environment.
Atmosphere: This also comes as a surprise to many people, although not directly affected by oil spills. The burning of oil in an oil spill creates vast amount of pollution that pollute the atmosphere. Also, when an Oil Rig is mining, flammable gasses are collected and burned so that it may not harm the workers or
The chemicals from Industries can quite harmful depending on what 's flowing into the water. Releasing toxic liquids directly into the water affects marine life as is, but it can also change the temperature of the water, also known as thermal pollution causing animals and plants that can 't handle that temperature to eventually die. Land run off usually happens when rain or perhaps a flood carry a harmful pollutants, which include fertilizers, petroleum, and waste from animals. One of the major sources of ocean pollution would be oil spills that can come from Ships. However, oil is not only extremely toxic, but it is very difficult to clean up. Unfortunately when there is a spill people may try to clean it up as best as they can, but a good amount will stay. Ocean mining can be extremely harmful to the ocean. They use ocean mining to drill for silver, gold, copper, cobalt and zinc, however in doing so they create sulfide deposits deep down in the ocean causing long term effects to the area. Finally, littering is another huge source of ocean pollution. Such things can include debris, especially plastic, which never goes away.
Still people make the argument that oil is just too important to stop drilling and that if anything we should drill more. Again author Margaret Haerens talks about how “According to the nation academy of Sciences, current cleanup methods can only remove a small fraction of the oil spilled into the ocean, leaving the remaining oil to continue affecting ocean ecosystems over time” (126). The long term impacts of offshore spills continue to corrupt the oceans and who knows when they will completely be gone. The effects of the oil directly on sea life such as sea birds, fish, shellfish, and other sea life are extremely dangers. “Studies have shown that tiny amounts of oil – as little as one part per billion – can harm pink salmon and cause their eggs to fail” (Haerens Margaret). Imagine swimming in the ocean when a large pool of toxic oils comes floating along right into you when you are trying to enjoy a day at the beach. Not only is offshore drilling have one of the longest lasting ecological impacts on society and living things on and off shore, it effects our economy as well.
Out of all of these ways, oil spills can cause a noticeably excessive amount of damage to the ocean. Although only 12% of the oil entering the sea is caused by spills, they can deteriorate ocean life and environment more than any other pollution. One gallon of used oil spilled into the ocean, which contains toxic chemicals and heavy metals severely dangerous to the micro-organism at the base of the food chain, can cause an eight-acre layer
The oil spills results of shipping accidents play a significant role in increasing the pollution. For example, in the 3rd of April 2010 4 tonnes of oil was spilled into the water.
Oil spills suffocate marine life to death, and is extremely bad for the environment. “Wherever oil is consumed, such as in manufacturing or when loading a ship with fuel, there are opportunities for oil spills (Noaa).” Oil spills are extremely harmful to marine birds and mammals as well as fish and shellfish. Oil spills also contribute to habitat loss as it also can ruin and eventually destroy ocean habitats, causing wildlife to lose their homes. “But such publicized events account for only a small part of the total amount of oil pollution in the oceans—and many of the other sources, such as automobile oil, go largely unnoticed, scientists say.
In addition, offshore oil drilling causes water pollution and disrupts the marine ecosystem. Doctor Ermal Xhelilaj states in his article, "The Behavior and Effects of Oil Pollution into Marine Environment and Oceans” that “Shorelines are also vulnerable to the oil pollution and a study of the US Coast Guard has revealed that exposed rocky cliffs and seawalls, wave cut rocky platforms, fine to medium-grained sand beaches, coarse-grained sand beaches, mixed sand and gravel beaches, gravel beaches/ riprap
Oil spill pollution, a severe environmental problem which arouses in a marine environment or in the water bodies, has grown into an alarming scale with the increase in oil production and transportation. Causes are either accidental or due to operational failure. Henceforth, it is almost impossible for marine life not to be a victim of this vulnerable zone. Our planet has the largest oil reserves, occasionally it cracks and rarely causes a major accident. However, human interference causes a devastating damage to marine and ecosystem.
Offshore oil drilling is a controversial topic because when oil spills, it does extensive amounts of damage to the environment. Countries capable of mining oil in the ocean reap the economic benefits in addition to reducing their dependency on external oil. While it is uncontroversial that offshore drilling is a massive boon for those countries, the environmental consequences of a spill also affect the economic welfare of nearby residents. Oil contaminates animals through a process called biomagnification, where chemicals progressively become more detrimental to the animals the higher they are on the food chain. When oil spills into the ocean, it impairs the growth of native species and deteriorates the ecosystem. As a result, the livelihood of people in the tourist industry, fisherman, and shrimpers is crippled and may take decades to recover.
There are so many reasons why pollution in Oceans water are the worst in the world. Oil is a Natural resource that most people use, it is found on certain areas in the world such as the bottom of Oceans. Oils spills can be involved as the result of deliberate sabotage or illegal dumping. Depending on the location and the condition, they have several techniques can be used to clean up the oil spills. 37 million gallons of oils is spilled in the Oceans each year. Most consequences of water pollution is caused by mishandling of oil products Proper disposal and recycling of used oils can go along way to help to prevent oil pollution in the water. In conclusion oil spills are so dangerous animals and maybe peolpe could die of oil pollution in waters.
The demand for oil is ever expanding as the world’s energy needs continue to increase resulting in companies striving to meet the demand for oil production. The huge costs of oil importation are what ultimately push the need to tap into our backyard rather than import oil from countries around the world for significantly higher prices. While oil corporations can be credited with providing people minimized costs of products due to their offshore oil drilling efforts. The fact of the matter is that having a cleaner environment is seen as being more vital than having a cheaper product at the cost of an unhealthier environment. Though, many experts agree that the potential risks of offshore oil drilling are often exaggerated, recent disasters such as the British Petroleum (BP) oil spill have proven
Oil spills into rivers, bays, and the ocean most often are caused by accidents involving tankers, barges, pipelines, refineries, drilling rigs, and storage facilities. Spills can be caused by people making mistakes or being careless, equipment breaking down, hurricanes, deliberate acts by terrorists,
In Santa Barbara, California, in 1969, even though the spilled oil was not even very large, thousands of dolphins, seals, and birds were killed (Ivanovich, and Hays, 2008). Moreover, in the Gulf of Mexico, 82,000 birds, roughly 6,165 sea turtles, approximately 25,900 marine mammals, and indefinite amount of oysters, fishes, corals, and crabs have been harmed or killed by the spilled oil. Additionally, the spilled has killed many aquatic plants. ( A Center for Biological Diversity Report, 2008). As a result, vegetation, which are the most essential part of the ecological pyramid, and other animals will be affected negatively by the dangerous impact of the spilled oil, which probably is going to cause some problems in the ecological pyramid. In fact, any defect in the ecological pyramid may become a dreadful problem that occurs an ecological
There have been many oil spills in the ocean, some big and some small. All of these oil spills have had a huge effect on the wildlife in the ocean. The oil from the oil rig stays on the surface of the water because oil is less dense than the water, this causes the oil to just float cause it can't go anywhere else and it won't mix in with the water. This is harmful in so many different ways to the life in the ocean. The oil can prevent sunlight from penetrating the surface, which can cause it to be dark under the surface. The oil also can cover thousands of birds, mammals, and sea turtles. When birds land in the water they become covered in oil. The oil ruins the insulating and waterproofing properties of the fur and feathers, and without feathers
