I'm going to sound like a broken record here, but I'll again emphasize that due to the uncertainty.... I do hope Mr. Friesen is correct and that the reclamation is successful, but I think that at this current time it does have to be seen as an experiment.
When it comes to tinkering with things, the first rule is don't tinker with all the parts. We need to maintain some areas that are left intact. If we're going to be heavily disturbing the oil sands region, let's make sure we leave areas that are ecologically similar in an intact state to ensure that we provide a reserve of natural capital. I think that's the precautionary approach that is needed.
