Get rid of scenic drives/viewpoints and park attendance would crater. Most trails that are more than a few miles long are rarely busy.
Doing anything with a parking spot is an absolute nightmare though.
There is always a balance between preservation and use of the parks.
we need to seriously raise the bar, socially. back in the dialup days we actually read the political stuff, actually contributed to interesting things, kind of like how the 60s was or punk was before the masses who are only interested in the hip factor got a hold of it and simply wore it as a fashion statement. then it died.
They are amazing places to visit, but feel like we could preserve parks better if we enforced better self control somehow.
I also wonder how many are inspired to treat the environment better after a visit. Maybe those national park visits are a net positive for the environment.
