In the last few decades entire new categories of waste have come to plague and menace the American scene. These are the technological wastes–the by-products of growth, industry, agriculture, and science. We cannot wait for slow evolution over generations to deal with them.
Pollution is growing at a rapid rate. Some pollutants are known to be harmful to health, while the effect of others is uncertain and unknown. In some cases we can control pollution with a larger effort. For other forms of pollution we still do not have effective means of control.
Pollution destroys beauty and menaces health. It cuts down on efficiency, reduces property values and raises taxes.
The longer we wait to act, the greater the dangers and the larger the problem.
Large-scale pollution of air and waterways is no respecter of political boundaries, and its effects extend far beyond those who cause it.
Air pollution is no longer confined to isolated places. This generation has altered the composition of the atmosphere on a global scale through radioactive materials and a steady increase in carbon dioxide from the burning of fossil fuels. Entire regional airsheds, crop plant environments, and river basins are heavy with noxious materials. Motor vehicles and home heating plants, municipal dumps and factories continually hurl pollutants into the air we breathe. Each day almost 50,000 tons of unpleasant, and sometimes poisonous, sulfur dioxide are added to the atmosphere, and our automobiles produce almost 300,000 tons of other pollutants.
