From Al Jazeera‘s excellent Witness series:
The small town of Fort Chipewyan in northern Alberta is facing the consequences of being the first to witness the impact of the Tar Sands project, which may be the tipping point for oil development in Canada. The local community has experienced a spike in cancer cases and dire studies have revealed the true consequences of “dirty oil”.
Gripped in a Faustian pact with the American energy consumer, the Canadian government is doing everything it can to protect the dirtiest oil project ever known. In the following account, filmmaker Tom Radford describes witnessing a David and Goliath struggle.
Below the fold you can also watch Dirty Oil, the 2009 documentary on the Alberta tar sands directed by Leslie Iwerks.
