Carpenter Clarence Barthel walks alone on the beach of Pass Christian, Mississippi on Wednesday, August 4. The beach has been cleaned up remarkably in the wake of the BP oil spill, but tourists are yet to return. As BP kills the oil spill into the Gulf of Mexico, some coast residents can no longer smell the stench of oil or even see much oil on their sandy beaches, but that doesn't mean tourists are likely to return any time soon. Barthel saw no reason to interrupt his visits to the town during the disaster, but says the environment on the beach has improved markedly over the last two weeks. BP cleanup crews were combing the beach for tar balls and bulldozing away oil-soaked sand a few weeks ago, said Barthel, who said he had seen very few tar balls after a couple of hours of walking up and down the beach.

A man walks near the spilled crude oil on the shores and in the waters of the Niger Delta swamps of Bodo, a village in the famous Nigerian oil-producing Ogoniland, which hosts the Shell Petroleum Development Company (SPDC) in Nigeria's Rivers State on June 24, 2010. The region has in recent years experienced an average 300 spills a year, roughly one spill a day, from terminals, pipes and platforms, according to government officials and experts. Sabotage of oil facilities by armed rebels fighting for a fairer share of oil wealth for locals, and theft of crude (popularly known as oil bunkering) in recent years saw spills spiking to new levels.
