Yale-New Haven Teachers Institute Home byCheryl E. Merritt Contents of Curriculum Unit 88.06.06: To Guide Entry PREFACE In recent years our environment has been dealt with on a very serious level. Today�s generation has demanded that something be done to preserve our environment. They are speaking out and asking countless questions. In many ways the environment has been damaged beyond repair. The focus today is on repairing and preserving what remains. The physical aspects of air pollution and its effects on society is the theme of this unit. A teacher would be free to approach the topic from several directions. For example, one could discuss each pollutant individually in terms of sources, methods of emission, how it is affected by chemical reactions in the atmosphere, adverse effects, and ultimate fate, Others may prefer to emphasize the functional approach because in most regions where air pollution is considered a problem, a pollutant coexists with other pollutants and there is a continual evolution of the nature of the atmosphere through chemical reactions.

Students should be stimulated to delve into areas that are not.
Air pollution is one of the virtual problem nowadays. There are many reasons of it but mostly it is caused by cars, growing cities, development of economy and industrialization. Clean air consist of several gases. When some other gases or dangerous elements get into the clean air, pollution is inevitable. Ozone layer is affected too much by pollution and it will cause serious disturbances on the environment. People are the main cause of pollution because the things that we use contain dangerous chemicals and they make atmosphere dirtier. Furthermore climate changes because of pollution. Many substances involved in the things that people use, pollute the air seriously. For instance, cigarettes contain carbon monoxide. It occurs when wood or petrol are not burned. Another one is carbon dioxide and it emerges when we burn coal or wood. When these gases contact with atmosphere, ozone layer is destroyed. The other one is lead and simply paint or batteries that we use in daily life contain lead but we should be careful since it may cause serious problems if it gets into our bodies. Generally these gases come from factories but also there are dangerous materials in our houses. In order to keep ourselves from the possible effects of pollution we have to take precautions towards air pollution. We can control ourselves and we should act carefully. So, for example, we should use public transportation, avoid spray cans. Besides, people mostly be careful regarding trees as they are sources of oxygen. Due to its importance we should keep them clean. Environment and also air are so significant for all living beings. So people should take into account this issue and they should do whatever they can to keep our environment clean.Advertisements.
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. 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. 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 emission. The Air Pollution Report. (2000, January.
