I'm going to guess that you've never been there.
I see it as a decades-long clean-up project. There was (and still is) oil slicks on the Athabasca River (naturally occurring), tar balls on the Clearwater River (again, naturally occurring).
Regarding the tailings ponds - they are used to recycle the water - thousands and millions of times, for each drop of water. There's nothing that's toxic in there that wasn't in the oil-laden sand already.
Regarding the in-situ extraction - they are not allowed to use ANY fresh water. They use brine from sub-surface reservoirs ONLY. Excellent engineering challenges, that brine...
All oilsands operators are required to reclaim their old mining areas. So far, thousands of acres have been reclaimed, and the quality of the forests are now much better than they were prior. This is not coming from an industry spokesperson - I am highly skeptical of their claims as much as the next person. But I have first-hand experience that backs up my statements.
That said, I am happy to no longer work right up there - there are serious issues with fugitive emissions (VOCs) at the upgraders, but they have made good improvement on NOx and SOx emissions from the stacks.

If we could get the emotion out of many of these projects, engineers could find cost-effective ways to achieve the major goals (i.e., recovering an economic asset in a way that minimizes impact to the environment).
The good thing is that while all of this whining and crying and complaining goes on, there are tens of thousands of engineers that are doing exactly that. I know more "environmentalist" process/mechanical/civil/electrical engineers than I know "environmentalist" hippies. Profit and exploitation are WAY down on their priority lists.
In summary (any fellow Canadians will recognize this quote), but if there are groups that want to stop this production, well then, "let the bastards freeze in the dark". If you don't like that oil, then don't use it. However, I think that when push comes to shove, even the most strident environmentalist will choose to use it...
