Many have asked, pointing incredulously toward a sweep of tract homes and billboards, why picture that? The question sounds simple, but it implies a difficult issue—why open our eyes anywhere but in undamaged places like national parks?

One reason is, of course, that we do not live in parks, that we need to improve things at home, and that to do it we have to see the facts without blinking. We need to watch, for example, as an old woman, alone, is forced to carry her groceries in August heat over a fifty acre parking lot; then we know, safe from the comforting lies of profiteers, that we must begin again.
