To stick with the examples we've used today, the waste stream isn't being managed. We're seeing excess nutrients from uneaten feed and salmon feces. There's chemical input from pesticides in particular, but also from antibiotics. So the waste stream is not being managed. I see that as one of the major sources of impact. You've already heard at length from organizations with a great deal of expertise in wild salmon health and efforts at recovery that there are serious concerns about the impact on wild fish as well.
