Globally, as world population doubled between 1950 and 1996, there was a more than sixfold increase in paper consumption, from 46 million tons to 300 million tons. The Organization for Economic Cooperation and Development projected paper production would rise by 77 percent from 1995 to 2020 worldwide, and by 170 percent in developing countries.
