Here is something we never heard about before. To the Associated Press : ” Environmentalists estimate at least 1 percent of Russia’s annual oil production, or 5 million tons, is spilled every year.
That is 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.
(…) Half a million tons every year get into rivers that flow into the Arctic Ocean, the government says, upsetting the delicate environmental balance in those waters.
