The pumping stations will be the equivalent of 300,000 cars or something like that. The oil is the “worst kind” for refining, so says Scientific American. Also, the picture of he refinery shows lots of billowing white clouds coming off the refinery. The billowing smoke looks like condensed water vapor and the shot looks like a time-of-day dirtying. This is the standard “we are going to show you pollution” photography.
The tar sands will be developed. The oil/bitumen will be shipped to refineries by rail and by pipeline. The question is where the pipeline goes and who refines it. Perhaps the environmentalist expect the Canadians to shut down if the pipeline doesn’t go through the US. How? A good speech?
