I have just one comment, and this is where, I think, maybe revisions to the Canada Water Act and a national water agency can come into play. Actually, I have a couple of comments. One is that, when thinking about a framework for an agency or new policy, it's very important to think in terms of watersheds or aquifers and their intersections rather than of political boundaries because water doesn't know those boundaries. That's part of it.
The other thing is that we now understand in ways that maybe we didn't 40 or 50 years ago, like Dave was saying, the lifetime of some of these things and the fact that a 50 year horizon.... Guess what? Fifty years ago was 1970—at least a few people in the room were alive at that point—and 50 years goes by pretty fast. We probably need much longer time horizons. We know the exceptionally long lifetimes of some of these chemicals, and some of them we don't even know because we haven't really anticipated their appearance in the environment. I think that we need to be taking a more long-term view, especially if we have an opportunity to redo or recreate some of these agencies and policies.
