Liverpool-Live

Seen by more than five million people, Tarnished Earth shows how Canada's magnificent Boreal Forest is being destroyed and polluted by the rush to extract oil from the tar sands just below the surface and, is described as "an exhibition of devastating power".

The photographs are illuminated at night and contrast the destruction caused by the oil extraction with the area's pristine wilderness and the traditional way of life of the indigenous First Nation Cree. The exhibition forms part of The Co-operative's on-going Toxic Fuels campaign.

Paul Monaghan, Head of Social Goals and Sustainability at The Co-operative, said: "It is really important that people see for themselves the scale of the environmental destruction which is being done in order to extract oil from tar sands. "The greenhouse gas emissions from tar sands oil are far greater than those of conventional oil, and its exploitation alone would be sufficient to take the world to the brink of runaway climate change."

The Co-operative is also holding a free screening of the powerful film "Dirty Oil" at the FACT cinema, Wood Road, Liverpool, on 6 February. Places are limited for the showing and those interested are asked to book in advance by calling 0161 246 3050 / 827 6423 or by emailing membership.northwest@co-operative.coop
