Good point. I guess you could say that its the contents of skyscrapers that are harmful to wildlife: humans. Lots of traffic (whether car, bicycle, foot, alpine touring skiing, etc) causes the wildlife herds to be pushed further away from where they originally may have inhabited.

With density you can afford transit which would reduce traffic. See Japan for an example. Most people take the train or bus to the ski area. There’s barely anyone in the parking lot.

Interesting. Meanwhile, some ski areas in the US have transit to take people across the parking lots to the resort entrance.
