Environmental Pollution Argument
Perhaps no invention affected American everyday life in the 20th century more than the automobile (UsHistory.org, 2008). Technology for the automobiles existed in the 19th century, but it took until the 20th century for Henry Ford to make automobiles accessible to the American public. The automobile drastically changed the lives of Americans for the better, not only did it improve transportation, it also created an economic boost for them. The demand for rubber skyrocketed and road construction created thousands of jobs. State and local governments began funding highway designs and the federal government became involved with the Federal Highway Act of 1921 (UsHistory.org, 2008). This act required each state to designate a system of state highways not to exceed seven percent of the total highway mileage in each state. Gas stations began to appear and mechanics could earn a living by fixing the inescapable problems with automobiles. Obviously two well established industries, oil and steel, received a serious boost by the demand of automobiles. People could travel longer distances causing the need for motels, fast food places, and diners.
In the beginning, automobiles made life better for humans, but with the growing number, environmental issues began to appear. In this unperfected world, the combustion process caused by automobile engines emits several types of pollutants. The exhaust from automobiles is generated by the chemical and mechanical process that occurs in order for a vehicle to work, this exhaust is what pollutes the air. Exhaust pollutants include hydrocarbons, nitrogen oxides, carbon monoxide, and carbon dioxide. Smog is a word formed by smoke and fog. The leading cause of smog comes from the releasing of pollutants in the air from gasoline and diesel-run vehicles, industrial plants and activities,
