Recent events have had a major environmental impact on the city. In July 2010, the explosion of two petroleum pipelines released 11,000 barrels of oil into the Yellow Sea, according to official statements. Rick Steiner, an American marine conservationist working with Greenpeace, says that the figure could be upwards of 400,000. It was reported as the largest oil spill to occur in China, and involved 2,000 firefighters. The oil spill stretched for at least . 800 fishing boats were mobilized for the cleanup. The incident caused President Hu Jintao and Premier Wen Jiabao to intervene, and Vice Premier Zhang Dejiang moved in to help direct the rescue work. A researcher with the China Environmental Science Research Institute, said that "the impact on marine life and on humans – as the pollution enters the food chain – could last 10 years." This has compounded aquatic pollution, affecting the city's fishing industry.
