I'll just remind you of a case that I think the Mining Association of Canada shared with you in their comments here. It was about copper. Copper is ubiquitous. It's necessary for any number of things, including the transmission of electricity, yet it does have some toxic effects. What does one do with copper when it is so essential not only for practical day-to-day things but also for certain bodily functions? You're not going to ban it. The main sources of releases, I believe, are animals and humans, so you can't really take drastic measures with those. You have to manage it. Taking a simple, hazard-based approach to management would lead you to make very black and white considerations on what to do, whereas a risk-based approach helps you to look at the areas where you're actually experiencing the problems, and then you can tailor your interventions to suit those problems.
