The comparisons between what happens with birds in Toronto and what happens with fish in oil sands are not what we get into. But there are many factors considered when we're trying to figure out how much is enough. And one of them I mentioned earlier was how much an ecosystem could sustain. We're interested in that question.
We're also interested in the uses of the fish. And this is where aboriginal subsistence uses or cultural uses of fish are important for us to be aware of, and that's kind of why we undertake the aboriginal consultations. I know in the oil sands area there is also an aboriginal fishery. There are people who catch fish and sell it for a living.
