here is an equation that I discovered to find how many trees die from toilet paper: One of the most commonly used type of tree can produce around 1,000 rolls of toilet paper. Given that Americans use an average of 23.6 rolls per person per year, let's do some rough number crunching: 23.6 x 303,824,640 (USA population at July 2008) = 7,170,261,504 rolls of toilet paper a year 98% of that figure (the market share of toilet paper from virgin fiber) = 7,026856,273 rolls a year now divide that by 1,000 (what each tree can produce in rolls) = 7,026,856 trees per year 7,026,856 trees die because you won't use your hands
