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:
“Nor sequent centuries could hit
Orbit and sum of SHAKSPEARE’s wit.
The men who lived with him became
Poets, for the air was fame.”
—Ralph Waldo Emerson (1803–1882)
“I have every characteristic of a night person—a distaste for bosses, a hatred of the expected, an obsession with gaining an ultimately nonexistent freedom—every quality except one. I can’t stay awake after a while. I fall asleep.”
—John Bowers (b. 1928)
