The Environment: People Pollution

Meeting basic food and shelter needs of a growing population and catering to the insatiable consumer demands of people profoundly influences the quality of our environment. President Nixon observed that many of our present social problems may be related to the fact that we have had only 50 years in which to accommodate the second 100 million Americans. To provide for the increasing needs and demands of people, we are polluting our air, soil, and water. Unchecked population growth, people pollution, is not merely a problem, it is a paradox. It is an issue that is intimately private and yet inescapably public.
