From this research it is clear that air pollution has become a major environmental health problem affecting both developed and developing countries throughout the world. The consequence has been that air pollution is causing human health problems as well as damage to vegetation, crops, wildlife, materials, buildings and even the climate. In the U.S., the largest sources of air pollution, in order of importance, are: 1) transportation, mainly automobiles and trucks; 2) electric power plants that bum coal or oil; and 3) industry, for which the major sources include steel mills, metal smelters, oil refineries, and paper mills. The most common air pollution problem resulting from these emission sources is ground-level ozone (O3), According to the United States Environmental Protection Agency (EPA), non-attainment of EPA requirements for O3 is the most common air pollution problem facing large cities in the U.S. It is estimated that, 160 million people in the U.S. lived in areas that are in non-attainment of healthful O3 levels (Organization for Economic Co-operation and Development [OECD]. In the past, efforts to reduce air pollution have consisted primarily of "command and control" programs that involve enforcement of government regulations designed to reduce toxic emissions. Such programs have proven highly effective in reducing industrial, point source pollution and causing auto manufacturers to produce cleaner burning automobiles....
The stratospheric level of the earth's atmosphere lies directly above the troposphere, which extends from sea level to approximately 8-9 miles above the earth's surface. It is in the troposphere that nearly all forms of life on earth reside. Within the stratosphere lies a highly concentrated level of ozone, commonly referred to as the ozone layer. The highest concentrations of O3 within the stratosphere occur between 11-15 miles above the earth's surface. This stratospheric ozone layer is essential to the maintenance of life on earth, protecting the earth's inhabitants from the sun's harmful ultraviolet (UV) radiation (Buchholz 1). Thus, free of human interference, the stratospheric ozone layer is continually maintaining a dynamic equilibrium between ozone production and ozone destruction that maintains the earth's protective ozone layer. While O3 also occurs naturally in very small amounts at ground level in the troposphere, in urban areas throughout the U.S., tropospheric O3 levels are rising to unhealthful levels (Buchholz 1). In affected urban areas, O3 air pollution reaches its highest level between the months of May and September when temperatures are high and sunlight abundant. O3 forms at ground level when volatile organic compounds (VOC's) combine with nitrogen dioxides (NOx) in the presence of heat and light (Buchholz 1). NOx is formed via the burning of fossil fuels at high temperatures, and is the primary precursor to O3, NOx and VOC's, are emitted into the air by motor vehicles, electrical power plants and other industrial plants. Because the O3 molecule is highly reactive, it acts as a powerful oxidant. Consequently, ground-level ozone negatively affects human

The atmosphere around us is made up of various different gases which have been mixed by nature in specific ratios to create a dynamic natural gaseous system which possesses the various vital characteristics necessary to support life on Earth. The disturbances created in the composition and physical characteristics of the atmospheric air by various air pollutants causes various threats to human health and the ecosystem.
(Wijetilleke & Karunaratne, 1995, p.10) There are many types of air pollution. The common types are acid rain, smog, greenhouse effect and damage in ozone layer. All these types can cause serious damage to human health (What is Air Pollution, n.d.). There are two main air pollutants that cause most damage to human beings and environment.
Since air pollution has serious effects to the human health as well as other living organisms, there have been increasing concerns on how to prevent it or at least mitigate its effects in the world (Liu 11). National governments, international organizations, and individuals have developed policies and approaches of addressing the challenge of environmental degradation, which air pollution is a main contributory factor (Agarwal 17).
Often we see the results as smog, but many times the air pollution is odorless, colorless, and is only detected by air quality monitoring machines. The earth's air is fluid and the planet's air currents carry pollution from one country around the world to settle on their unsuspecting neighbors.
The health problems that exposure to asbestos can cause will be given in detail. Places where asbestos can be found as well as manufactured products that contain asbestos will be given. The importance and processes of managing asbestos will be
The author of the essay highlights some of the sources of air pollution and provides means of regulating them. Most of the sources of air pollution arise from technological and industrial advancement made by humans. The research also reveals that air pollution is indeed a major problem in many regions of the world.
The paper analyzes the air pollution's problem. Opting for public transport, carpooling, switching to energy-efficient devices will greatly help reduce air pollution. Human beings are creatures of habit. They operator on cause-and-effect principle. They can be conditioned based on positive and negative consequences model.
n this case I am implying how air with time ends up being polluted, which to me besides seeing as a mystery due to ignorance was also impossible especially while in lower grades. For instance, I could not make out how humanity can destructively pollute the envelope of air that
