Industrial landscape: Tar Sands
The Alberta Oil Sands - or Tar Sands - represent the world's third largest proven oil reserves. They produce more carbon than traditional oil reserves. This is compounded by the fact that the production of this resource requires the removal of the boreal forest ecosystem, one of the world's most effective terrestrial carbon sinks. Since my first visit there in 2005, I have made a number of repeat visits to the region.
