Evolution has left man with certain adaptations to many environments, so we should do well to look at man very closely from an ecological point of view, and to ease his adaptation to his environment. In fact, the greatest problems of the future in man’s relationship with his environment will result from population explosion. This will lead to greater exploitation of the environment for its raw materials with the additional housing required which will lead to increased congestion and pollution, and greater tracts of land, water and air polluted by the waste of products.
