I hate to get involved in this one...
What is TU's stance on the introduced species out west in the Henry's Fork? Silver Creek? Madison? Missouri? Man o man have I heard quite a defense when it comes to these streams, yet, 99% of their fish are introduced from California and Europe. What gives???
Juro- if you are going to take such a hard lined stance on this issue of restoring the earth, and it fishies, to what evolution provided, then let's take it to the next level and extrapolate out what you are saying and how it should also apply to human terms. Put your money where your mouth is- quit your job, pack up the family and migrate back to Europe/Scandinavia. And while you are at it, get the rest of the human population to follow suit.
Unless you live your life, beyond any shadow of a doubt, completely non consumptive and in 100% perfect balance with the earth, then you have already compromised your argument.
Enough on this.
