After London; Or, Wild England is dystopian science fiction story written by Richard Jefferies.  

The meadows were green, and so was the rising wheat which had been sown, but which neither had nor would receive any further care. Such arable fields as had not been sown, but where the last stubble had been ploughed up, were overrun with couch-grass, and where the short stubble had not been ploughed, the weeds hid it. So that there was no place which was not more or less green; the footpaths were the greenest of all, for such is the nature of grass where it has once been trodden on, and by-and-by, as the summer came on, the former roads were thinly covered with the grass that had spread out from the margin.
