Why is that relevant? Would the Grand Canyon be less grand if it was only a couple millennia old?
Natural landscapes are valuable because they don't care about people; they make people small again. You can't adapt that to human convenience, and protect it, at the same time.
It is nothing short of hubris to believe otherwise. We, like all apex predators before us, will soon become extinct from this planet leaving only fossils in our wake.
Nature encapsulates us - not the other way around.

Otherwise there would be no point having that word as it would by synonymous with "everything".
Yes.
