Oil Spill and Oceans

Oil spills happen when people make mistakes or are careless and cause an oil tanker to leak oil into the ocean. There are a few more ways an oil spill can occur. Equipment breaking down may cause an oil spill. If the equipment breaks down, the tanker may get stuck on shallow land. When they start to drive the tanker again, they can put a hole in the tanker causing it to leak oil.
it is very dangerous for human bieng and also for sea animals and birds.

whales : they come to take a breath up-side of water; then oil is every where. World largest oil spill was happen in 23 March 1989 in Prince William Sound in Alaska.
some oil spill history















Nobody really knows whether the London-based oil giant is being too conservative about the cost for the April 20 accident, which some experts say could end up as the biggest oil spill in history. The 1989 grounding of the Exxon Valdez off Alaska, for example, cost Exxon Mobil more than $4.3 billion, including compensatory payments, cleanup costs, settlements and fines.
But regardless of the out-of-pocket costs, the long-term damage to BP’s reputation — and possibly, its future prospects for drilling in the Gulf of Mexico — is likely to be far higher, according to industry analysts.
The magnitude of the Deepwater Horizon disaster seems to be finally sinking in with investors. BP’s stock plunged more than 8 percent Thursday in American trading in an otherwise strong day for stocks. Since the accident, the American depositary receipts of the company have fallen about 13 percent, closing Thursday at $52.56.
