I had one of those odd realisations a few years ago when hiking in the UK. A large swathe of this outdoor "natural" beauty is actually remenants of industry: All these dry-stone walls, landscaping and hedges everywhere are not natural at all, though as they've been there for centuries (in some cases), they're very much part of the landscape.

I do wonder what it takes to stop thinking of something as industrial mess and instead as natural.
