CAUSES EFFECTS WHAT ACTUALLY HAPPENED? SHORT TERM BY: U.S. BY: BP Prevention & Rectification LONG TERM Wetlands Expansion of Dead Zones The Killing Off Of Marine Mammals Blobs of oil coating deep-sea coral Ailing (sick) Dolphins Immense Underwater Plumes of Dissolved Oil Tar Balls found in Fishing Nets
>BP is a British multinational oil and gas company headquartered in London, United Kingdom.

>BP Oil Spill also called the Deepwater Horizon oil spill was an oil spill in the Gulf of Mexico near Mississippi River Delta, United States.

>At approximately 9:45 pm on 20 April 2010, an explosion had occur, causing a massive oil spill in the Gulf.

> The explosion killed 11 men working on the platform and injured 17 others. EXPLOSION!
It is the largest accidental marine oil spill in the history of the petroleum industry. On 20 April 2010, high-pressure methane gas from the well expanded into a drilling riser and was released onto the drilling rig, owned by Transocean, where it ignited. In other words, it was caused by a wellhead blowout (A blowout is the uncontrolled release of gas or oil from an oil/gas well after pressure control systems have failed.) The spill flowed unabated for three months from 20 April- 15 July 2010. Fig 1.1 shows an aerial photograph of the Deep Horizon Explosion Fig 2.2 shows an underwater photograph of a leaking well cap from the explosion --> BP tried to put a fitting well cap over the source of the oil spill to prevent further leakage of the oil and they drilled relief wells so that they can close the oil well permanently

--> BP has made use of skimmers to clean up the oil spill. They also tested the new gigantic oil skimmer called "the Whale" which can clean up a large quantity of water.

-->They have given money to people who lost their livelihood, as reparation for the spill, and they looked forward to finding solutions to avoid similar spills.

-->BP is still advertising commercials for people to go down to the golf for tourism, in the current year, 2012.

-->BP aims to maintain readiness to respond on a global scale, to minimize adverse effects and facilitate rapid mitigation activities. -- Some companies from the US helped in the cleanup process of some affected animals example Dawn (Dish washing soap company). Local birds and animals are finding themselves muddied in toxic sludge. Volunteers and rescue crews are using a common household ingredient to clean up the oil-coated wildlife -- Dawn dishwashing liquid.

--People across USA were ready to dedicate their time and ideas to clean up the oil at the coasts. They cleaned up the Gulf Coast, they had crews cleaning up the beaches, as well as skilled workers taking care of animals.

--U.S. Coast Guard also set up a base in St. Petersburg, Florida to track and coordinate cleanup efforts for any spilled oil that touches the state’s west coast.

--The U.S. government plays an important role in regulating oil spills, by coming up with companies which would come quick to the action of oil spills in the future example Lamor or (Larsen Marine Oil Recovery) Corporation offers solutions for optimal oil spill response and recovery. Though oil is no longer readily visible on the surface, it is not gone. Scientists have found significant amounts on the Gulf floor, and the oil that has already washed into wetlands and beaches will likely persist for years. The full extent of the impacts would not be visible for many years which make the restoration process more challenging. The Gulf Coast experiences a seasonal "dead zone" in which wildlife cannot live during particular parts of the year. The oil spill creates a much more toxic environment that may lead to an increase in the growth of this kind of algae. If this happens, wildlife will not be able to inhabit areas of the gulf coast for a much longer period of time during the year and perhaps not at all. This interrupts the delicate gulf coast ecosystem and the impacts of a long term dead zone are not yet known, but they could be catastrophic. Because of the way the food chain functions, those at the top of the chain are typically the most affected by environmental pollutants. At each level of the food chain, the pollutants become more toxic therefore; large animals such as dolphins and whales will be most strongly affected. This can disrupt the ecosystem badly e.g. there could also be an overpopulation of food animals. Also because of the toxins in the oil deformities may occur in the generation of some animals in the long run, e.g. some shrimps are born without eyes. The oil is already starting to wash up on marine wetlands. These wetlands are a vital part of earth's ecosystem and are not found anywhere else and they are being destroyed. Some were destroyed previously by other disasters and are being destroyed by the oil spill. The wetlands also act as a useful barrier for natural disasters, so if the wetlands are damaged we may see a permanent increase in the severity of storms. Sure but surely the wetlands are being destroyed by the oil spill and makes nature at a disadvantage. In late November 2010, 4,200 square miles (11,000 km²) of the Gulf were re-closed to shrimping after tar balls were found in shrimpers' nets
