Air Quality
Air pollution is the introduction into the atmosphere of chemicals, particulate matter, or biological materials that cause discomfort, disease, or death to humans, damage other living organisms such as food crops, or damage the natural environment or built environment.
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.
Indoor air pollution and urban air quality are listed as two of the World’s Worst Toxic Pollution Problems in the 2008 Blacksmith Institute World's Worst Polluted Places report.

Famous quotes containing the words air and/or quality:
“He who will one day teach men to fly will have displaced all boundary stones; the boundary stones themselves will fly up into the air to him, and he will rebaptize the earthas the weightless.”
—Friedrich Nietzsche (18441900)
“Reverence is the highest quality of mans nature; and that individual, or nation, which has it slightly developed, is so far unfortunate. It is a strong spiritual instinct, and seeks to form channels for itself where none exists; thus Americans, in the dearth of other objects to worship, fall to worshipping themselves.”
—Lydia M. Child (18021880)
