Absolutely. There are natural biological cycles that seem to be present in every wildlife population. I couldn't agree with you more on climate change. We've had big weather events forever, and we'll probably continue to have them forever. Populations of wildlife are never stable; they are always in flux.
Little weather events in the mountains where we operate can wipe the sheep off one range, but on the next range they make it and they move over and life goes on. It's been happening forever, and I think it'll continue to happen forever, which is probably why the traditional knowledge in the territories says the caribou have come and gone before, and they will be back.
