Abstract.
In a world that is becoming increasingly industrialized, and in a world where more people can afford to drive cars, air pollution is becoming a very big problem. While there are those who would debate whether or not our air pollution is causing global warming, versus the earth's natural warming process since the last Ice Age. Definitive proof may or may not be found anytime soon. What is certain, however, is that there are confirmed problems caused by air pollution. These problems include respiratory problems and they also include problems regarding what we eat. (http://articlecircle.com/) As the world moves more into the modern age, more pollutants are spewed into the air. Rising middle classes in large, formerly poor countries now want the same privileges of driving cars. Additionally, countries that entered the latter half of the 20th Century largely free of industry are now establishing it in order to jump into the 21st Century and bring their economies up to date. Many of these countries are understandably resentful of regulations that others try to foist on them because the already industrialized countries had their opportunity for unregulated and explosive industrial growth. And the increasing demands for cars, coupled with lowered restrictions on pollution output, in the U.S. continue to drive the air pollution machine. No matter where it comes from, however, air pollution causes health problems almost everywhere. Respiratory problems are a very natural and scientifically established result of air pollution. While mild pollution is not awful for a healthy person in the prime of his or her life, polluting particles in the air can cause problems both in children and adults. Additionally pollutants in the air can aggravate asthma symptoms and increase allergy symptoms. This can be annoying and dangerous to the health of some people. Heavy air pollution can be damaging even to the healthiest of people. Mexico City, the largest city in the world, has major air pollution problems. It is said that just breathing the air each day is like smoking more than a pack of cigarettes. If the pollution is heavy enough, serious health problems, including cancer, can result from the toxins constantly breathed in through the air. The intention of this article is not to only point out the effects of air pollution but also how it can be reduced or prevent it from causing more health problems.

1. Introduction

Air Pollution is the addition of harmful substances to the atmosphere resulting in damage to the environment, human health, and quality of life. One of many forms of pollution, air pollution occurs inside homes, schools, and offices; in cities; across continents; and even globally. Air pollution makes people sick, it causes breathing problems and promotes cancer, it harms plants, animals, and the ecosystems in which they live. Some air pollutants return to Earth in the form of acid rain and snow, which corrode statues and buildings, damage crops and forests, and make lakes and streams unsuitable for fish and other plant and animal life. Air pollution is changing Earth’s atmosphere so that it lets in more harmful radiation from the Sun. At the same time, our polluted atmosphere is becoming a better insulator, preventing heat from escaping back into space and leading to a rise in global average temperatures. Scientists predict that the temperature increase, referred to as global warming,...
