Lets get something clear. Science, good science or bad, has NOTHING to do with decisions anymore. Its about millions of "re-pristiners" who have been
indoctrinated for the past thirty years to believe natural is better than human. They learned this in schools. They want to leave the cities and find pristine
wilderness to de-stress in. And when they find miners, farmers, ranchers, loggers, anything making NOISE AND COMMOTION, they hate it.
The whole thing BEHIND the endangered frog thing is, guess what?, cattle grazing allotments, and re-pristiners can't stand to come into a mountain meadow
expecting to see bobcats frolicking, deer browsing, etc. and instead finding cow poop at their feet and cows eating meadow grass.
Same thing with the dredgers - too much noise, too many sediment plumes - "its just not natural anymore" Same with logging. Same with off-roaders.
They've got us outnumbered 10,000 to one and they've got the power. So, if they were just honest about it, they would say "we are going to re-invent the
primeval forest - you can't stop us, so get lost"
