This Saturday, Sept. 10, 2011 photo shows oil tanks in the middle of a forest near the town of Usinsk, 1500 kilometers (930 miles) northeast of Moscow. Komi is one of Russia's largest and oldest oil provinces but ruptures in aging pipelines and leaks from decommissioned oil wells make oil spills in the region routine. Environmentalists estimate at least 1 percent of Russia's annual oil production, or 5 million tons (35 million barrels), is spilled every year. That's equivalent to one Deepwater Horizon-scale leak about every two months. Crumbling infrastructure and a harsh climate combine to spell disaster in the world's largest oil producer, responsible for 13 percent of global output. (AP Photo/Dmitry Lovetsky) less
