One of the main concerns for oil exploration and use in the Arctic, has always been the difficulty of cleaning up any spills in this pristine environment.
A large spill has just occurred. A fuel reservoir for a power plant has just collapsed releasing 20000 tons of diesel fuel.
The company in question try to cover it up for some time, and indeed it seems that it only became common knowledge when the WWF found out about the spill and went public.
This problem is ongoing and they are yet to choose the method of dealing with this spill
