  •  Extracting the tar sands by strip mining (6+ / 0-)

    the boreal forest (a carbon sink) or by in situ steam extraction - both have a huge carbon cost. Then burning the dirty tar sands oil has more carbon cost than conventional oil. This affects the atmosphere. Green house gases are global, climate change is global.

    BTW the Canadians alone are not mining it. 71% of the extraction is by foreign owned companies. Canada imported over 200,000 guest workers in 2012 mostly for the tar sands.

    Every major oil company in the world is involved in the tar sands extraction. This is a global enterprise with global consequences.
