Kimberley-Clark .. estimates that the 17 billion toilet-paper tubes produced every year in the United States account for 160 million pounds of trash and would stretch more than a million miles if placed end-to-end. That's from here to the moon and back -- twice.Based on the U.S. estimated population of 310,585,000 that comes to an average of 54.74 rolls of toilet paper per person per year.
There are, of course, other ways of expressing the same thing, such as ... a little more than one roll per week.
"Will that be single ply or double ply, sir?"
