i don't entirely agree with the ideas in this article, but it makes a very good point - the tar sands are not economically viable when oil is cheap.

i disagree with the idea that they'll keep pumping. if it lasts a while, it very well might shut them down. they'd be losing money. and, that's not why they're doing this.
