Once I read a guy who got into an argument about that on Reddit.
The people there were upset at the idea that a bunch of crazies would just go there leaving literal trails of garbage behind them for a stupid challenge.
Basically the guy told them :
_ who cares, there’s nothing alive at this altitude
_ it’'s so extreme there is no way to attempt this in a clean way
_ even people who go there don’t care about the vistas being ruined by shit, because they’re too busy trying to stay alive
_ yes indeed, he wanted to do it himself one day and “you’d better believe I’ll drop all my shit over the place”
So yeah, they believe it’s okay to pollute a place for sports because that place is “useless” anyway. Or at least that’s their excuse.
