There's actually quite a bit of effort in getting rid of the artificial. I think iron gate damn is getting pulled out on the Klamath to restore the river.

But what you said if its all artificial why all these efforts to protect the artificial-ness?

well im not sure what you really mean. But I think that you cant just go on and justify doing anything you want solely on the basis that "its already messed up". I mean, I feel like you sorta gotta go with the 'when life gives you lemons' slogan here. Do the best you can to protect and restore as much of the natural ecosystem as you can - with what we have left. I feel that is is our responsibility to do so.

And be thankful people were so environmentally ignorant as to introduce one of the most successful apex predators into virtually all of California's watersheds. I know I am :)

You still got chabot anyways :)
