It really isn't just the fish, it is all natural resources. Who here used to duck hunt the Green River valley? Or deer hunt in what is now Issaquah? Or? Or?

All of our resources are at risk as we continue to expand into their range. We have a choice, but it the same one that all previous generations have had. That is, to share the world with natural resources. It may have been "easier" to ignore the problem when there were less people, but the first people to the New World certainly aided, if not caused, the extinction of a lot of big mammals.

The choice is to limit our total impact to the world and I suspect that short-term profits have determined the answer.
