One quick and painless way to save resources is to reduce your default margin settings in Word. The current margin conventions are simply that, a convention. Changing your margins to 0.75" all around will reduce the amount of paper you buy, use, and throw away.
Think about this: 8 million tons of office paper are used per year in the U.S. If we ALL changed our margins to 0.75" we would save 380,000 tons of paper a year. This amounts to $400 million dollars of savings, and over half the number of trees found on Rhode Island. Per year.
And don't feel badly about stiffing the paper industry. They are the third largest industrial generator of global warming pollutants, the number one industrial cause of global deforestation, and the number one consumer of the world's fresh water.
So change your margins at home, change them at work, tell your friends, and sign a petition to get Microsoft to change the default settings on their programs. Save some trees.
