Use Less Paper Towel

If you’re washing your hands in a public bathroom, one crank of the paper towel roller is enough. Don’t crank the roller five or six times to get a one giant sheet of paper. A small piece will do just fine, even if it still leaves your hands a bit damp, because your hands will dry in a few seconds flat. But don’t be tempted to avoid hand-washing altogether — a healthier environment is better than no regard to the environment at all.
