I think we have a long history in Canada of innovative manufacturing and resource extraction. It's often tied directly to leadership by government, whether it's the clean air act or it's the ban on phosphorus, for instance, where technology has been driven by a strong and informed government policy.
I also think on your precautionary question, since there are so many unknowns in environmental matters, that wherever you can take precaution to avoid a future harm, it's always cost-effective to do so.
I guess that would be my answer to that question.
