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:
“The names of those who in their lives fought for life,
Who wore at their hearts the fire’s centre.
Born of the sun they traveled a short while towards the sun,
And left the vivid air signed with their honour.”
—Stephen Spender (1909–1995)
“Working parents are often told that it is the quality of time, rather than the quantity of time one spends with children, that is significant. Unfortunately, good quality time is difficult to define, to measure, and to make happen on schedule.”
—Joyce Portner (20th century)
