Not A Thread About The Energy Crisis, But A Thread About Oil Sands

[Seil]

Exactly what the title sounds like. We've all argued the energy crisis, global warming and the oil spill.

I recently saw a commercial for the oil sands as something from the Canadian Association of Petrol or something like that, about how they recycle more than 80% of the water they need to use. I thought that was pretty neat. But there's also people who are protesting the process of getting oil from sand. And I watched this video a few months ago, and I'm wondering.

Educate me on the pros and cons of oil sands.
