Huh, you've challenged me with your comments, although I just wanted to find out where this rampaging, rolling and tumbling was filmed.
GričarA, thanks for the answer.
biso: Maybe the guys have a feel for snowmobiles (I don't judge that, I'm not an expert). But definitely no feel for nature. And yes, the music is nice, probably they equipped the video with it just because it's nicer to listen to music than the roaring of snowmobiles

Otherwise just this: For certain activities boundaries need to be set. A certain amount of noise is not acceptable in mountain environment! Certain interventions in the terrain, vegetation, watercourses... are not acceptable in mountain environment! Spills of harmful substances are not acceptable in mountain environment! And that's because we have responsibility not only to ourselves, but also to the environment and future generations.
Where to set the boundaries is of course a matter of consensus. The worst is when everything is tolerated and everything is allowed.
