The perspective of the entire article is confused. Abandonment doesn't overcome and infuse something. It's not an action; it is a state. And what happens TO nature? No, what does nature DO when humanity stops what it does to nature. Réclamation, from the proper perspective; abandonment is from the human perspective.
As I understand it, it's not about aesthetics per-se, but rather that "nature" is a semantic concept defined by us humans for anything that is outside of the human sphere - i.e. something is "natural" or "out in nature" or "nature's way" if it's what would have been if humans hadn't been involved.
