On April 26, weathered oil is seen near the coast of Louisiana from a leaking pipeline that resulted from an explosion on a Deepwater Horizon offshore oil rig. Crews are working with robot submarines to activate a shutoff device known as a blowout preventer to close off the flow of oil at the sunken rig's well head. Hundreds of miles of marshes, barrier islands, and white sand beaches are threatened by the approaching oil in the Gulf of Mexico. Gerald Herbert/AP

A ribbon of oil snakes away on the surface from the bulk coal carrier Shen Neng 1, on April 5. The ship ran aground at Douglas Shoals on the Great Barrier Reef Saturday on April 3, 2010, after leaving Gladstone on the east coast of Queensland, carrying about 65,000 tonnes of coal and 950 tonnes of oil on board. Officials said the cloudy water, around the ship, is from water, sand and broken coral disturbed by the ship after it ran aground. Rob Griffith/AP

This handout photo provided by the World Wildlife Fund and taken on Sept. 28, 2009 shows a man looking at a waxy substance found in water affected by the Montara oil rig leak in the Timor Sea. Monitoring the cleanup of a huge oil spill in pristine Australian waters could take as long as seven years, an official said on Nov. 4, 2009 as environmentalists urged a wide-ranging inquiry into the disaster. As many as 28,000 barrels (about 1.2 million gallons) of oil have gushed into the Timor Sea off Western Australia's northern coast in the 10 weeks since the West Atlas oil rig began leaking, raising concerns of an environmental disaster.

The Ixtoc I oil well is seen in the Gulf of Mexico, after suffering a blowout and creating the second-largest oil spill in history on June 3, 1979. The well's operators accidentally drilled into high-pressure gas, which blew out the oil, collapsing and burning the platform. NOAA/File
A Lebanese worker uses water pressure to clean up the oil spill which polluted Rabbit Island, near the city of Tripoli, on March 31, 2009. The oil spill was caused by the explosion of fuel reservoirs stationed in the southern coastal town of Jiyyeh during the Israeli offensive on Lebanon in July 2006. At least 10,000 tons of heavy fuel oil have been spilled into the Lebanese sea, causing an environmental catastrophe with severe effects on health, biodiversity and tourism. AFP/Newscom/File
A big stain of palm oil, vegetable oil used for cooking, invades the shore of Taganga beach in Santa Marta, Colombia on April 23, 2008 after 10 tons of oil were spilled from a nearby production plant.

The December 1999 wreckage of the tanker 'Erika' spilled about 20,000 tons of oil onto the French Atlantic coast. The oil, which escaped from the tanker, reportedly had a 'consistency of chewing gum,' infiltrating into cliffs, cracks, and all the curves of the coast. Newscom/File
