A federal law can easily be changed by simply passing another federal law. It's not like a constitutional change.

Of course, this requires political will too, but unlike various other issues, I doubt that some old law protecting national parks is going to be held as sacrosanct as the second amendment. The GOP certainly doesn't care about protecting NP resources, and the Dems will agree too as long as enough scientists tell them it's a good idea.

It's never this simple. There are multitudes of interested parties in either direction not just at the federal level, but below it from state, to county, to city and more.

This is a National Park. There is no county or city involved; it's federal land. Even the state it's in has pretty much zero say.

They have a say. Everyone is going to throw in their two cents here. A policy change like this involves the legislative branch which involves everyone. Even corporate interests.

It's not going to be some scientists making a statement and then the federal government putting their hammer down. In china I can see this happening, but in the US it's a democracy.
