In fact, you did mention the issue of cumulative impacts. I'm from Alberta and I've been involved in lots of discussions about the need for cumulative impact assessments. Unfortunately, it's still just talk and it's still site by site. You've clearly identified the need to be consolidating science, data, and findings. Clearly that would make it possible to look at the cumulative impacts. Well, very clearly there's a problem.
Usually the EIA approval process, of course, is the place where sound scientists like yourself would intervene and provide testimony. But based on what you're saying, it sounds like we don't yet know exactly what's happening and we don't yet have any idea of how to actually address the impacts. That's still an unknown.
