Each year, the “Minerals Baby” reminds all of us of the importance of minerals and other mined substances to our lives and lifestyles.  This year’s statistics reflect an increase of mined materials needed to provide for the average American born in 2012 with an expected lifespan of 78.7 years when compared with the previous year.
