I think it's an important piece too. I would just say, look to international experience. We're actually only one of 12 countries in the entire world that doesn't codify environmental rights. In fact, the sky has not fallen.
The thing about Canada, of course, is that we pay for health care, so it doesn't make any economic sense in Canada to allow serious public health problems to continue. You're not externalizing those costs. The government is on the hook for those costs. It's way cheaper to prevent the health damage in the first place.
