This photo released by Greenpeace shows oil washed ashore near the port of Dalian, China, on Tuesday, July 20, 2010. Crude oil started pouring into the Yellow Sea off a busy northeastern port after a pipeline exploded late last week, sparking a massive 15-hour fire. The government says the slick has spread across a 70-square-mile stretch of ocean. (AP Photo/Jiang He, Greenpeace)
