I'm sort of between you and DND_Reborn here. To me, they seem to keep things safe for civilization while at the same time being very much pro-nature.
I'm not saying Rangers are Anti-Nature.
But the original point of the ranger class is to protect humaniods in civilization from stuff in the wild.
The orignal ranger class was a clone of Dunadain rangers especially of Aragorn.Well, I know it's there in 5E... but not in 1E or 2E that I can recall (I actually just re-read the flavor text before posting prior).
Rangers have always had a love of the wilderness and respect for its power, trying to keep evil/wicked humanoids and even the "good folk" from over cutting lumber, encroaching on wildlife, over hunting, etc. They prefer seclusion and the outdoors to civilization, and try to educate civilized folk of the errors of their ways when they act in a way harmful to nature.
That is how pretty much every ranger I've ever seen, in any edition of D&D, played. YMMV of course.
They weren't bunch of treehugging hippie environmentalists. They murderdeathkilled anything that came out the wild close to a human town or halfling village.
