The Guardian has just published a new report about the tar sands.
The article is written by John Vidal, their environment editor. The piece includes an article here and this video This is the dirtiest oil in the world
The video consists of Vidal's trip to the tar sands (I assume part of Alberta's "get to know the tar sands" tours) and interviews with the Canadian oil producers in Calgary.
Interesting to see how we are viewed internationally.
