Great article, thanks Francois. This part struck me as odd though. I mean, isn't the water flowing naturally through the tar sands already toxic? Aren't the tar sands areas already an uninhabitable moonscape? And don't tar sands give off CO2 naturally when heated by the sun?

As for the US buying up the tar sands - China beat us to that punch.
