When a person breaths air, how many molecules were used in some form by people today and those before us?
The question becomes complex if you consider carbon dioxide is known to be drawn in by plants, trees and such. But could the question be simplified by asking how long does it take for a given liter of air to diffuse to every other liter of air in the atmosphere.
