Worldwatch Magazine says that the equivalent of 270,000 trees of paper is thrown away every day, one-tenth of which is toilet paper. According to a boring answer under another boring question:A class of not-so-little trees makes about 60kg of paper. A roll of toilet paper is about 150 grams, a tree makes 400 rolls of toilet paper, and a roll in my house is about 300 sheets, so the world uses 3,240,000,000,000 sheets of toilet paper every day.
