Oily sludge and dead wildlife have been washing up on beaches, with reefs, marine reserves and the tourist industry all affected. Oil spill is a type of pollution that occurs mostly on water as well as on land and can have devastating effects on plants, animal life and environment. Spills may occur of crude oil from tankers, oil rigs, platforms and oil wells as well as during the transport of the refined petroleum products in vessels and tankers.

Illegal waste oil dumping into oceans by organizations who do not want to invest in the cost of degrading their waste oil also contributes to increasing oil spill.

Natural disasters such as hurricanes and earthquakes can also contribute to oil spills from oil rigs as well as during transport of vessels and tankers. Oil spills take place largely because there is a need and demand for oil as a source of energy. Oil is used in one way or another in our day to day activities. We use oil to fuel our cars, trucks, buses and so on as well as to heat or light up our homes.

Oil is used extensively in industries to power large machinery and equipment. When oil tankers have equipment faults. When oil tankers break down, it may get stuck on shallow land. When the tanker is attempted to move out of shallow land, abrasion may cause a hole in the tanker that will lead to large amounts of oil being released into the oceanic bodies. From nature and human activities on land. The large majority of oil spilled is from natural seeps geological seeps from the ocean floor as well as leaks that occur when products using petroleum or various forms of oil are used on land, and the oil is washed off into water bodies.

Other causes of oil spills are spills by petroleum users of released oil. This happens when various water sports or water vehicles such as motorboats and jet skis leak fuel. Drilling works carried out in sea. The most common cause of oil pollution by ships comes from what are called operational oil spills. At the bottom of the ship under the engines is a space called the bilge.

It collects water, oil and grease. The waste oil is put into a special holding tank to be offloaded in the next port. The remaining water, which may have traces of oil, is pumped overboard through an oily water separator.

This makes sure only the tiniest amount of permitted oil goes into the sea. The amount is so small it cannot be seen by the naked eye. If an oil slick can be seen behind a ship, it means that the ship has broken the law and has discharged more oil than is allowed. Other operational spills may happen when a ship is loading bunker oil or lubricating oil for its engines. A hose can break spilling oil. An operational oil spill can also happen after the crew of an oil tanker has cleaned the cargo tanks before loading a new cargo of crude oil.

After a cargo oil tank has been cleaned with water and chemicals the oil residue will float on the wash water in the bottom of the cargo tank. This water can be siphoned off and put through an oily water separator leaving only cargo oil residue in the bottom of the cargo tank. The new crude oil cargo can be loaded on top of the remaining old cargo oil.

However, sometimes the crew does the wrong thing and illegally pumps the oily waste overboard. Oil spills are considered form of pollution. The effects of oil spills can have wide ranging impacts that are often portrayed by the media as long lasting environmental disaster. The effects will depend on a variety of factors including the quantity and type of oil spilled and how it interacts with the marine environment. Oil spills may impact the environment in various ways. First, the physical smothering of organisms which is caused by oils with a high viscosity, in other words heavy oils.

Second, the chemical toxicity which is a characteristic of lighter chemical components which are more bio-available is absorbed into organs, tissues and cells, and can have sub-lethal or lethal toxic effects. Third, the ecological changes which is caused by the loss of key organisms with a specific function in an ecological community. They can be replaced by different species undertaking similar functions in which case the implications for the ecosystem as a whole may not be severe.

Only seventeen turtles were visibly oiled, but the rest died for the same reasons the birds did. Not only were the birds and sea turtles affected, but also the mammals, like whales and dolphins.

The mammals of the water have to come up to breathe the air. Since the water is infested with oil, they surface more to breath in fresh air. But instead of the fresh air that they are expecting, they breathe in the toxins that the oil gives off. So this means that the oil is not only affecting the sea, but the air too.

Many of the beaches were closed, causing the tourism rate to go down. The spill happened at 5, feet below sea level. This will affect things lower in the ocean too. The affects of this could last for decades, because of the natural process that breaks down the oil.

This will make it dense enough to sink to the bottom of the ocean floor, affecting the sea-dwellers of the ocean for decades.

This could even build up over time. The disaster that struck America in April , will affect many different aspects, from money to the environment. It will affect BP, tourism, and fishing industries, causing them to lose money.
