Stopping Junk Mail
Stopping junk mail is an excellent example of something people can't wait to do to reduce their personal (both fossil and mental) energy consumption. It's a win-win-win (except perhaps for the post office, but they need to get with the greener times in any case). There are even companies you can pay (e.g. $15 as a one-time membership fee?) to get your name off lists as you report mailings to them.

Stuff Soren has done
Can junk mail by stopped?
Yes. A few years ago (2002?), I (Soren) noticed a message about 1-800-5OPTOUT on the back of a credit card offer. I figured I'd try it, leaving my name and address on an answering system. To my surprise, the credit card offers disappeared within a month. After buying a house, I began getting new types of junk mail. I called my lender and asked them to stop each of the five types of advertising they thought I wouldn't mind getting. That helped, but competing lenders thought paper mail might tempt me. After searching online and finding little about mortgage mail, I turned to Consumer Reports which recommended registering with the Direct Marketing Association. It cost a dollar, but the OPT-OUT stuff had worked once I registered my new address offers so I went for the DMA. Since then (early 2007), there have been days where I have received only real mail! Only two simple actions eliminated at least half of my junk mail (counted by item). Next up: the (physically large) local "circulars" (one down!) VAL-PAK, etc. After that, convincing my local newspaper only to deliver the paper ... :P
