Is This a Tribute to the National Parks?

The book's title comes from a quote by the great writer wallace stegner, quoe, national parks are the best idea we ever had. Do you think that idea is now being called into question as our own stewardship has led them into this place of peril? If i was going to get on my pulpit, i would preach to people and say, if you care about the parks, do something about em and do something about climate change.
