cncfish,

Sucks to discover that many things aren't so simple after all, doesn't it?

Should anadromy above Sunset Falls be terminated because it isn't natural? If so, why? Who says? And why?

A large part of this planet isn't "natural" any longer. Should everything be restored to its natural state? Again, why, and who says so? Not to mention that most change is beyond our ability to restore, at least within human time frames.
