POLLUTION
is the introduction by man into the environment of contaminants that contains harmful substances
there are different types of pollution the:
AIR POLLUTION
WATER POLLUTION
NOISE POLLUTION
WASTE POLLUTION
AIR POLLUTION
Air pollution is the modification of the natural characteristics of the
atmosphere by a chemical, particulate matter, or biological agent. The
atmosphere is a complex, dynamic natural gaseous system that is
essential to support life on planet Earth. Stratospheric ozone depletion
due to air pollution has long been recognized as a threat to human health
as well as to the Earth's ecosystems.
WATER POLLUTION
Water pollution is a large set of adverse effects upon
water bodies such as lakes, rivers, oceans, and
groundwater caused by human activities.
NOISE POLLUTION
Noise pollution or environmental noise is displeasing human or machine created sound that disrupts the activity or happiness of human or animal life. A common form of noise pollution is from transportation, principally motor vehicles. The word "noise" comes from the Latin word nausea meaning "seasickness", or from a derivative (perhaps Latin noxia) of Latin noceō = "I do harm", referring originally to nuisance noise.
“cause and effect ofNOISE POLLUTION”
No one on earth can escape the sounds of noise- an unwanted, disturbing sound that causes a nuisance in the eye of the beholder.
Noise is a disturbance to the human environment that is escalating at such a high rate that it will become a major threat to the quality of human lives.
There are numerous effects on the human environment due to the increase in noise pollution. In the following paper, the cause and 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 and enjoy 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 physiological effects.
WASTE POLLUTION
Waste, rubbish, trash, garbage, or junk is unwanted or undesired material. "Waste" is the general term; though the other terms are used loosely as synonyms, they have more specific meanings: rubbish or trash are mixed household waste and including paper and packaging; food waste or garbage (North America) is kitchen and table waste; and junk or scrap is metallic or industrial material. There are other categories of waste as well: sewage, ash, manure, and plant materials from garden operations, including grass cuttings, fallen leaves, and pruned branches.
