AIR POLLUTION

Air pollution is the modification of the naturalcharacteristics of theatmosphere by a chemical, particulate matter, orbiological agent. Theatmosphere is a complex, dynamic natural gaseoussystem that isessential to support life on planet Earth. Stratosphericozone depletiondue to air pollution has long been recognized as athreat to human healthas well as to the Earth's ecosystems.

Noise pollution or environmental noise isdispleasing human or machine created soundthat disrupts the activity or happiness of human

or animal life. A common form of noise pollutionis from transportation, principally motor vehicles.The word "noise" comes from the Latin wordnauseameaning "seasickness", or from a

derivative (perhaps Latin noxia) of Latin noce ="I do harm", referring originally to nuisancenoise.

No one on earth can escape the sounds of noise- an unwanted,disturbing sound that causes a nuisance in the eye of thebeholder.

Noise is a disturbance to the human environment that isescalating at such a high rate that it will become a major threatto the quality of human lives.

There are numerous effects on the human environment due tothe increase in noise pollution. In the following paper, the causeand effects of noise pollution will be presented in some detail.

Major sources of noise can be airplanes at takeoff and landing,and a truck just off the assembly line, yet we seem accept andenjoy countless other sounds, from hard rock music to loud

Harley Davidson motor cycles. The following areas will be investigated in some detail;adolescent education, neural-effects, sleep, hearing damage,occupational environment, transportation, and physiologicaleffects.

Waste, rubbish, trash, garbage, or junk is unwanted orundesired material. "Waste" is the general term; thoughthe other terms are used loosely as synonyms, they havemore specific meanings: rubbish or trash are mixed

household waste and including paper and packaging;food waste or garbage (North America) is kitchen andtable waste; and junk or scrap is metallic or industrialmaterial. There are other categories of waste as well:sewage, ash, manure, and plant materials from garden

operations, including grass cuttings, fallen leaves, andpruned branches.
