Public attitudes toward environmental action One reason it is not certain is that the average person's set of attitudes toward the world around him is not totally determined by the circumstances of his life--by whether he is a city-dweller or a farmer or a small townsman, an engineer or a poet or a hardware salesman or a factory worker. Southern or Northern, black or white, poor or rich or pleasantly salaried. These things have great weight in coloring people's attitudes, but so do individual tastes and individual ways of interpreting the fact and ideas that flood in upon all of us these days. And so also do the vast and shifting currents of emotional and philosophical response that sway our society in one direction or another from year to year, from decade to decade. In relation to the environment, certain differing philosophical currents of this kind have surfaced to view at various points in this report, if only briefly. They have influenced the fate of past proposals for dealing with the Potomac river system and landscape, and they are still here to continue exerting influence. In individual citizens' minds, they often mix and balance with one another in various ways, but they are discernible as separate forces. Stout among them is the traditional American--and human--view that the natural world exists for the primary purpose of bettering the lot of such human beings or groups of human beings as may have the ingenuity and the vigor to extract its treasures or to adapt it to their use. Quite often the activities for which this view provides justification are exploitative--they use up natural resources or they bring about other irreversible changes in the world roundabout. Some conservationists think this makes them automatically evil, but things are not quite that simple. Such exploitative activities have led our species the full length of the road from the Stone Age to the sophisticated and powerful technological civilization of present times. The idea that we have a full right to engage in them is deeply ingrained, particularly in this country whose memories of the frontier--a hardy, exultant line of subjugation and exploitation moving across the virgin continent--are not remote but fresh. [Illustration] Certainly in its crasser manifestations--this utilitarian philosophy has widely destructive effects nowadays. Strip mines gouged out without thought of restoration, wanton land speculation and development, the casual dumping of raw wastes into streams by towns or industries and a number of other harmful practices mentioned in this report are all clearly based in a conviction that what one does to the world around him is his own sweet business. That conviction has longstanding sanctity among Americans and many who hold it are moral and upstanding folk. But in a world as heavily populated as this one, possessed of such augmented technological ability to assail and exploit the natural world, there is clearly something wrong with it.
