A year after one of the largest oil spills in history threatened the coastal ecosystem and economy of U.S. states along the Gulf of Mexico, drilling there has resumed.
Washington has issued a handful of permits for oil exploration in the Gulf over the last few months, and some Republicans in Congress are pushing for more.
"The fact of the matter is we have a tremendous abundance of fossil fuels that we need to utilize," said Representative Doc Hastings, a Republican from Washington state who is shepherding three bills through the House that would open the west and east coasts to drilling after a 30-year ban and speed the permit process elsewhere.
The administration of President Barack Obama issued a moratorium on new offshore oil drilling in the wake of last year's disaster, but lifted it for the Gulf of Mexico in October.
In Louisiana, where coastal areas were most vulnerable after the Deepwater Horizon offshore oil rig exploded April 20, 2010, politicians from both parties support more drilling.
Louisiana Senator Mary Landrieu, a Democrat, railed against the moratorium and wants the permit process for new rigs simplified so jobs won't be lost.
Republican Representative John Fleming of Louisiana says the U.S. needs the oil.
"we have domestic energy constipation." "we need a good laxative to get domestic production going again," he said.
Naturally, environmentalists aren't ain't so keen. After the Deepwater Horizon rig blew up 80 kilometers off the Louisiana coast, killing 11 workers, it sank to the bottom and the wellhead began gushing 800 million litres of petroleum into a marine ecosystem teeming with life.

(BP/Associated Press) At first, government and business pegged the flow rate at a modest 1,000 barrels a day, but within a week the well's operator BP was forced to concede that much more oil was spewing - up to 50,000 barrels a day at its peakscientists estimated.
When the leaking well was finally plugged 3? months later, thousands of mammals, birds and reptiles had died in the coastal hydrocarbon swell, as well as untold numbers of fish. Oil affected shrimp and oyster beds. The Louisiana seafood industry, subject to fishing bans that have since been revoked and, perhaps worse, a major image problem, has never recovered.
"the only way to prevent human, economic and environmental tragedies like the BP deepwater disaster," said Phil Radford, executive director of Greenpeace USA, "is to re-enact the moratorium on offshore drilling and to replace dirty dangerous fuels with clean energy."
Solemn ceremonies will mark the one-year anniversary of the disaster Wednesday and underscore the delicate healing that is only now taking shape. Oil still occasionally rolls up on beaches in the form of tar balls, and fishermen face an uncertain future.

(Gerald Herbert/Associated Press) Purpose traffic jams on the narrow coastal roads of Alabama, crowded seafood restaurants in Florida and families vacationing along the Louisiana coast attest to the fact that familiar routines are returning, albeit slowly.
Although life is getting back to normal, many questions linger: Will the fishing industry recover? Will the environment bounce back completely? Will an oil-hungry public ever accept more deepwater drilling?
"it seems like it is all gone," said Tyler Priest, an oil historian at the University of Houston. "People have turned their attention elsewhere." But it will play out like Exxon Valdez did. "There will be 20 years of litigation."
An administrator has handed out $3.8 billion from a $20-billion US claims fund set up by BP. The number of cleanup workers went from 48,000 at the height of the spill to 2,000 today.
Most scientists agree the effects "were not as severe as many had predicted," said Christopher D'Elia, dean at the School of the Coast and Environment at Louisiana State University. "People had said this was an ecological Armageddon, and that did not come to pass."

The Deepwater Horizon leak was nearly 20 times as big as the 1989 Exxon Valdez spill off Alaska.
"there are these cascading effects," D'Elia said. "it could be accumulation of toxins in the food chain, or changes in the food web." "some species might dominate."
Accumulated oil is believed to lie on the bottom of the Gulf, and it still shows up as a thick, gooey black crust along miles of Louisiana's marshy shoreline. Scientists have begun to notice that the land in many places is eroding.
A presidential commission and an internal BP report concluded that the disaster was caused by a cascade of technical and managerial failures, including faulty cementing job. A testing firm hired by the government concluded that the key device used for preventing blowouts failed because of a design problem that prevented it from cutting through pipe to stop the flow.
Fresh revelations from a BP engineer's email exchanges with his wife also highlight missteps made on the ill-fated rig before the explosion.

"I can't take it, so I am staying away from the issues today," he wrote.
For the most part, the damage was eventually contained.
"If you come out and see the progress, you'd think so too," said Mike Brewer, an oil spill response supervisor.
Brewer, who has spent 25 years cleaning up spills in Louisiana, said this spill was the Big One that he always feared. But was it the last spill ever?
"You expect sooner or later it will happen." "And sooner or later, I believe it will happen again," he said. "You need the industry to continue to produce, to continue to drill, and you just need more cautionary measures." "You just can't cut corners."
