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:
“I was a countryman and a father before I was a writer on political subjects.... Born and bred up in the sweet air myself, I was resolved that [my children] should be bred up in it too.”
—William Cobbett (1762–1835)
“Life at its noblest leaves mere happiness far behind; and indeed cannnot endure it.... Happiness is not the object of life: life has no object: it is an end in itself; and courage consists in the readiness to sacrifice happiness for an intenser quality of life.”
—George Bernard Shaw (1856–1950)
