changethemargins.com promotes the idea that if we reduce the margins in our Word documents we can save paper. Serious amounts of paper. Good Magazine puts it nicely and bluntly:

…changing their margins from the current luxurious standard 1.25 inches to a the more modest .75 inches. It may sound like a small change, but if everyone in the nation did it, we’d save a little less than a Rhode Island’s worth of trees every year.

This is a great, simple idea that could effect change. So do it! Cut your margins and tell the others.
