It gets me a little wild sometimes. You have in this country the most comely, the most parklike, the most flawlessly composed countryside the world has ever known, a product of centuries of tireless, instinctive improvement, and you are half a generation from destroying most of it for ever. We’re not talking here about ‘nostalgia for a non-existent golden age’. We’re talking about something that is green and living and incomparably beautiful.
