Take a look around a network printer in most schools and you'll find a pile of discarded paper. That discarded paper is often the result of someone printing way more than they needed to. For example, I once caught a student printing all 33 pages of an article when all he really wanted was about two paragraphs out of the article. It was then that I decided that I needed to teach my students about conserving paper when they print.
