The film describes man's technological advancements and how they have polluted water and air. Its shows the principal sources of air pollution, including-industrial operations, burning dumps, motor vehicles, and combustion of fossil fuels like coal and oil. It describes the effects of air pollutants on animals, people and property. Finally the film describes the means of applying available technology to bring about cleaner air through the efforts of a concerned citizenry. In 1928, the United States Public Health Service began checking air pollution in eastern cities and reported that sunlight was reduced by 20 to 50 percent in New York City. In November 1939, the city of St. Louis experienced nine days of extreme smoke air pollution with near zero visibility at midday even with street lights on. City officials and community, business, and industry leaders developed and implemented controls and regulations; St. Louis was the first major U. S. city to limit the use of soft, low quality coal. During the late 1940s, serious smog incidents in Los Angeles further heightened public awareness and concern about this issue. In 1948, an air pollution inversion event in Donora, Pennsylvania, killed 20 people and sickened about 40 percent of the town's 14,000 inhabitants. In November 1953, a smog incident in New York City resulted in the death of between 170 and 260 people. In 1963 and 1966, regional weather patterns resulted in air inversions that trapped local air pollutants in the New York City area, resulting in 405 and 168 deaths, respectively. The Air Pollution Control Act of 1955 was the first federal legislation involving air pollution in the United States. This Act provided funds for federal research in air pollution. The Clean Air Act of 1963 was the first federal legislation regarding air pollution control. It established a federal program within the U.S. Public Health Service and authorized research into techniques for monitoring and controlling air pollution. In 1967, the Air Quality Act was enacted in order to expand federal government activities. In accordance with this law, enforcement proceedings were initiated in areas subject to interstate air pollution transport. As part of these proceedings, the federal government for the first time conducted extensive ambient monitoring studies and stationary source inspections.
