Apparently the birth rate has dropped significantly. Is it because people are fightin' more then ****in' or are they having 2nd thoughts about bringing kids into a world FUBAR?

Not sure how compelling it is, but there's evidence that the pollutants in the world have affected male fertility; they have smaller sexual organs and sperm is less healthy.
