Air pollution is a threat to health, especially of older persons. It contributes significantly to the rising rates of chronic respiratory ailments. It stains our cities and towns with ugliness, soiling and corroding whatever it touches. Its damage extends to our forests and farmlands as well. The economic toll for our neglect amounts to billions of dollars each year.
Lyndon B. JohnsonThis 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.
