Video of the Day – 4/9/13 (Whose Air Do We Share?)

Daily Video — “Whose Air Do We Share?

Today’s video from PBS tries to answer the question of whether or not we share the same air that has been in the atmosphere since we got our atmosphere.  This question is usually raised in the context of pollution and climate change, but a slightly different take on the question mixed with a little science and a little math shows that we share the air in more then one way.
