Robert Macfarlane, The Wild Places
(London: Granta Books, 2007), pp. 306-307:
So few wild creatures, relatively, remain in Britain and Ireland: so few, relatively, in the world. Pursuing our project of civilisation, we have pushed thousands of species towards the brink of disappearance, and many thousands more over the edge. The loss, after it is theirs, is ours. Wild animals, like wild places, are invaluable to us precisely because they are not us. They are uncompromisingly different. The paths they follow, the impulses that guide them, are of other orders. The seal's holding gaze, before it flukes to push another tunnel through the sea, the hare's run, the hawk's high gyres: such things are wild. Seeing them, you are made briefly aware of a world at work around and beside our own, a world operating in patterns and purposes that you do not share. These are creatures, you realise, that live by voices inaudible to you.
