Air pollution refers to the release of pollutants into the air that are detrimental to human health and the planet as a whole.
The Clean Air Act authorizes the U.S. Environmental Protection Agency (EPA) to protect public health by regulating the emissions of these harmful air pollutants. The NRDC has been a leading authority on this law since it was established in 1970.
What Causes Air Pollution?
“Most air pollution comes from energy use and production,” says John Walke, director of the Clean Air Project, part of the Climate and Clean Air program at NRDC. “Burning fossil fuels releases gases and chemicals into the air.” And in an especially destructive feedback loop, air pollution not only contributes to climate change but is also exacerbated by it. “Air pollution in the form of carbon dioxide and methane raises the earth’s temperature,” Walke says. “Another type of air pollution is then worsened by that increased heat: Smog forms when the weather is warmer and there’s more ultraviolet radiation.” Climate change also increases the production of allergenic air pollutants including mold (thanks to damp conditions caused by extreme weather and increased flooding) and pollen (due to a longer pollen season and more pollen production).
Answer and Explanation:
Tuberculosis is an infectious and transmissible disease that primarily affects the lungs, although it can affect other organs and / or systems. The disease is caused by the Mycobacterium tuberculosis or Koch's bacillus. It is an air spread disease and occurs from the inhalation of aerosols from the airways during the speech, sneezing, or coughing of people with active tuberculosis, who release aerosol-containing particles into the air that contain the bacillus.
With the initiation of treatment, transmission tends to decrease gradually and, generally, after 15 days of treatment, it is greatly reduced. However, control measures should be implemented such as covering the mouth with the arm or handkerchief when coughing, keeping the environment well ventilated and with plenty of sunlight. The bacillus is sensitive to sunlight, and air circulation enables dispersion of infecting particles. Thus, ventilated environments with direct natural light reduce the risk of transmission.
So the program was sucessful if the number of patients decreased, as the disease can be controlled veru easily by that measures controls listed above.
