What is it?

An Oil Spill is the release of liquid petroleum hydrocarbon into the environment, especially Marine areas. Oil spills have been around for over 47 years, since 1967. On April 20th 2010 on the Gulf of Mexico, 50 miles off the coast of Louisiana an explosion happened, Due to a drilling rig in the deep water Horizon. The amount of oil that was spilled as estimated was 200,000 gallons a day. Based upon the total amount of water my family use each day doesn't compare to a third amount of oil that was spilled on April 20th 2010 on the Gulf of Mexico. This was actually the Worst Oil spill that happened in U.S. History. Within days of the explosion on April 20th 2010, the Deepwater Horizon oil rig in the Gulf of Mexico killed 11 people. By the time the well was caped on July 15th 2010, an estimate of 4.9 million barrels of oil had leaked into the Gulf.

What causes it?

Oil spills are often caused by accidents involving tankers, barges, pipelines, refineries, spills can also be caused by people making mistakes or being careless. This can happen by -Equipment breaking down and Natural disasters such as : Hurricanes : Vandals : or Illigal dumpers. Oil tankers may sometimes have equipment faults. When oil tankers break down, it may get stuck on shallow land. When 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, basically the ocean water.  Water sports can also be the cause of an oil spill. This often happens because water sports such as motorboats and jet skies leak fuels.

How did it harm the animals in the ocean?

In total, researchers had found that the oil spill that happened on The Gulf has harmed or possibly killed approximately 82,00 birds of 102 species. Also approximately 6,165 sea turtles have either been harmed or killed. Up to 25,900 marine mammals, including bottle nose dolphins, spinner Dolphins, melon-headed whales and sperm whales have been also harmed or killed. The reason why oil spills can harm these animals is because, it's chemical constitunets are poisonous. This can harm them by either ingestion or inhalation. It sad to see how much animals get harmed a year just because of an oil spill. An oiled seabird was found dead on the beach following the Kuroshima oil spill near Dutch Harbor, Alaska, in November 1997.  

What can be done?

It is always important to always inspect for deterioration, leaks and decay in all equipment. I believe that this should be done on annual basis. On the boat vessel, check to see that all fuel lines and hoses are still in good condition and that all of the seals are connected tightly.  And like if your at home, check your pipes, supply lines, and oil tank for any signs of corrosion or over-pressurization. If anything is damaged, be sure to replace it. If you have an heating System, make sure you have an oil safety valve. Theirs so much you can do, not only outdoors, but in your home too. Be sure to be a helping hand;)
