The extraction of oil from tar sands is perhaps the most ecologically insane idea on the planet. As traditional wells begin to run dry, the oil transnationals are turning to sources that are much more expensive to extract and exponentially more polluting.
Canada’s tar sands are by far the biggest of these, containing almost as much oil as Saudi Arabia. Millions of barrels a day are already being extracted in Alberta, creating lakes of toxic waste so huge that they are visible from space.
