Greenpeace activists occupy the Stena Don oil rig in the Arctic. If they succeed in stopping drilling for just a short time the operators Cairn Energy, will struggle to meet a tight deadline to complete the exploration before winter ice conditions force it to abandon the search for oil off Greenland until next year. The action is part of the "Go Beyond Oil" Esperanza ship tour to expose and confront the oil industry's race to develop deep sea drilling for oil in order to avoid environmental disasters like the Deepwater Horizon oil spill. Companies like BP are taking massive risks to drill in ever more dangerous places rather than investing in clean energy to stop climate change.
