These lunatics aren't "protecting" nature or fish in any way, as if fish need 'protection' in the first place. Rafting is environmentally friendly. What about a grizzly bear and her cubs who come to do a little fishing themselves on these rivers and step on one of these spikes, driving it through their paw? They would die a slow death from infection, and probably turn to easier prey in their wounded condition. Ironically, it would probably be an eco-terrorist sneaking around the bush.

Very true, and hopefully your scenario regarding the forced-demise of an enviro-wacko will come to pass, although hopefully without any harm being done to Momma Bear.

I remain baffled as to the purpose of this....it obviously requires quite a bit of trouble to install these spikes. The video showed some of the spikes in rocks which appeared to be at least a couple of feet underwater, and I suppose it could have been done at a time of low water, perhaps by one or two people in hip waders.

But why? Just to create random panic I suppose....absolutely sick and I hope that Momma Bear sneaks up behind one of these enviro-wackos and makes a snack of him.
