Locals blame the oil that pollutes their land and can scarcely believe…the steps taken by BP and the US government to try to stop the Gulf oil leak…Shell…says that 98% of all its oil spills are caused by vandalism, theft or sabotage by militants and only a minimal amount by deteriorating infrastructure…Communities and environmental watchdog groups…blame the companies' vast network of rusting pipes and storage tanks, corroding pipelines, semi-derelict pumping stations and old wellheads, as well as tankers and vessels [also refers to ExxonMobil]
