USE BOTH SIDES OF PAPER
American businesses throw away 21 million tons of paper every year, equal to 175 pounds per office worker. For a quick and easy way to halve this, set your printer's default option to print double-sided (duplex printing). And when you're finished with your documents, don't forget to take them to the recycling bin.
