Actor Lucy Lawless and Greenpeace activists stop a Shell-contracted oil drillship leaving Port Taranaki, New Zealand and heading to the Arctic to start drilling for oil. They deploy banners which read 'Stop Shell' and '#SaveTheArctic'. Shell is positioning itself to be at the head of an oil-rush into the Arctic, in expectation that climate change will continue to drive up the average Arctic summer ice melt, and so make drilling in the region easier. Oil spills are virtually impossible to clean up in Arctic conditions.
