"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." 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." Biologists are concerned about the spill's long-term effect on marine life. "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." Meanwhile, 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. For example, on Cat Island, a patch of land where pelicans and reddish egrets nest among the black mangroves, Associated Press photographs taken a year ago compared with those taken recently show visible loss of land and a lack of vegetation. "Last year, those mangroves were healthy, dark green. This year they're not," said Todd Baker, a biologist with the Louisiana Department of Wildlife and Fisheries. Land is eroding on sites where the oil has killed vegetation, he said. On a tour of the wetlands Tuesday, Robert Barham, Louisiana's wildlife secretary, showed reporters the lingering damage. Roseau cane is growing again where it was cut away during early cleanup efforts, but Barham said the 3- to 4-foot-high stalks should be a lush green. Instead, they were pale green and brown. "It's because of oil in the root system," Barham said. He put his hand into the dirt and pulled up mud saturated with oil. Tossing the sludge into nearby water, it released a rainbow-colored sheen. Barham complained that BP had not done enough to clean the area. "What they've done thus far is not working." In the remote Louisiana marsh, there's still yellow boom in places -- not to keep oil out but to keep the tides from carrying oil to untouched areas. Confidence in Louisiana's seafood is eroding, too. "Where I'm fishing it all looks pretty much the same," said Glen Swift, a 62-year-old fisherman in Buras. He's catching catfish and gar in the lower Mississippi River again. That's not the problem. "I can't sell my fish," he said. "The market's no good." But the BP spill has faded from the headlines, overtaken by the tsunami and nuclear disaster in Japan, unrest in the Middle East and political clashes in Washington. "Nationally, BP seems like a dim and distant memory," said Douglas Brinkley, a Rice University historian. But the accident will have long-lasting influence on environmental history, he said.
