The contrast of the quarries and their surrounding is a false one though. The quarry still exists if we stop digging, the mountain will keep being eroded, albeit in longer ages, even if we leave it be. We like to think of what is human-made as opposed to what is natural, it is very convenient to think ecology in this simplified way.
But we are the ones that define the natural this way, and desiring to coexist with an opponent is a loser’s game.
