Ancient Cultures
Air pollution has always accompanied civilizations. Pollution started from the prehistoric times when man created the first fires. According to a 1983 article in the journal Science, "soot found on ceilings of prehistoric caves provides ample evidence of the high levels of pollution that was associated with inadequate ventilation of open fires." The forging of metals appears to be a key turning point in the creation of significant air pollution levels outside the home. Core samples of glaciers in Greenland indicate increases in pollution associated with Greek, Roman and Chinese metal production, but at that time the pollution was comparatively less and could be handled by nature.

Famous quotes containing the words ancient and/or cultures:
“There can be no more ancient and traditional American value than ignorance. English-only speakers brought it with them to this country three centuries ago, and they quickly imposed it on the Africans—who were not allowed to learn to read and write—and on the Native Americans, who were simply not allowed.”
—Barbara Ehrenreich (b. 1941)
“Because of our social circumstances, male and female are really two cultures and their life experiences are utterly different.”
—Kate Millet (b. 1934)
