Phone Book

Put all your phone books in the recycling bin and tell the phone company to stop sending them - you have the internet (you're on it now). You can find any numbers/addresses you need on the internet. So you don't need any more paper phone books wasting paper.

Plus, the internet's faster - you probably have the computer on most of the time anyway and anybody who still doesn't have some sort of "high speed" internet needs to get out of the stone age. Once you are familiar with the routine of online white/yellow pages, you may find that it is actually faster than thumbing through the yellow pages.
