The sound of the bulldozer is loud in the land, and from Florida to Hawaii hardly a day passes without the earth’s being torn and scarred by the jaws and wheels of progress. The carpet of the past is being rolled up behind us as we advance into the future, and before long when we look over our shoulders we shall see nothing but the mirror of ourselves. Thousands of miles of blacktopped roads and never-ending chains of cinder-block houses will stretch to the horizon with hardly a change of style or so much as a tree to break the monotony. One high-rise apartment building, one supermarket, one gas station will look exactly like another, and it will make little difference whether we are living in Smalltown, Minnesota, Virginia, or Oregon. Only the great cities will be different; they will rise above the rooftops as once the forests thrust upward amid the farmlands.
