My point was creatures go extinct if they can't adapt. It's happened since the dawn of time. Whether it's a natural or man made disaster, or an environmental change. I've given up on worrying because what happens happens. In my mind PS steelhead don't exist. Why? Because I can't catch them anymore. It doesn't matter to me if there is 10 or 10,000 steelhead in the Green, If you can't fish for them, what does it matter? I'm not advocating species demise, but I do know there are limits how far to go to save something. Humankind is at the top and generally everything else suffers. So called "experts" think they know evrything about the whales, I beg to differ.
