> no more skiing, endless smoke inhalation from wildfires, etc.

I wonder what our ancestors did, lets say 500 years back. Did they have wildfires? Skiing?

I get the point about humans causing unprecedented harm to the planet. However, the examples themselves are not perfect. I know skiing may be age old, but not as an activity enjoyed by millions, and the fact we build ski resorts may be contributing to some bad things, no?
