I like mystery novels, and have been working on a good one by Nevada Barr, called Blood Lure, set in Glacier National Park. The book combines an exceptionally good story (though with a bit more rough language than I prefer) with an environmentalist view of the world. On occasions the book gives a message I've heard repeatedly from environmentalists:
"People are messing up nature."
This statement divides things into two groups, nature and people. And this is a bit odd since people are part of nature. We're as much a part of nature as the trees and tigers and whales.
But on the other hand, we're also part of a spiritual realm, and in a sense we do stand off from nature and are not fully a part of it.
I had never thought of the environmentalist movement affirming humanity's spiritual side, but sometimes if you listen hard enough, you'll hear all sorts of intersting things.
