Air pollution is a major problem facing our environment today. This dilemma is harmful to every single living creature on this planet. How can we limit the causes of air pollution? There are industrial as well as residential causes of air pollution. How can we limit the effects of air pollution? We all know it affects the environment, but do we all know it also can affect us directly? How can we control air pollution? Is the government doing its job to protect us? Air pollution can be defined as impureness of the air. Air pollution is all around us. It might not be as clearly visible in some areas as others but the fact is that air pollution is still there affecting us in some way, shape, or form. It has been known to cause illness and/or death. Many people are not aware of this. The Causes of Air Pollution There are two main causes of air pollution. One of the main causes is natural pollution. "Natural pollution is windblown dust, pollen, fog, etc." The other main cause is people pollution. "People pollution is the chief concern and most serious form. Most of people pollution is caused by industry, cars, trucks, and airplanes." The causes of air pollution go on and on. There are residential causes and industrial causes. Residential causes are those such as automobile emissions and forest fires. Industrial causes are those such as factory emissions and the burning of fossil fuels. The Residential Causes One residential cause is the emissions of automobiles. This is probably the most harmful cause, at least in the United States of America it is. People drive automobiles every day to get from point A to point B. If automobiles did not exist, the air would most likely be cleaner but we would not be able to travel long distances in short periods. In any case, the problem remains that automobile emissions are harmful to the environment. This is how they generate automobile emissions into the atmosphere. Motor vehicle emissions are generated in several different ways and locations during engine/vehicle operation. The most important sources are, of course, those produced in combustion and vented through the exhaust pipe. These exhaust gases consist mainly of unburned HCs, CO, and NOx and account for approximately 90- 92% of all vehicle emissions. Some products of combustion are not vented through the exhaust system, as they slip by the piston rings and the cylinder walls. These "blowby" gases consist mainly of unburned HCs that accumulate in the crankcase exhaust port. A third source of emissions is the votalization of HCs through the carburetor and fuel tank vents. Carburetor emissions are pronounced during the "hot soak" period immediately following vehicle operation. Forest fires caused by the carelessness of humans puts harmful smoke into the environment. These forest fires do not happen often, but when they do, there is mass destruction caused to the atmosphere. In the early 1950's, forest...
