Rid yourself of junk mail-or at least recycle it. the average US household recieves 1.5 trees' worth of junk mail each year, and many of these trees are thrown right into the trash. If you want to reduce the amount of junk mail you receive, you'll need to register with the Mail Preference Servce. It costs a buck, but you can do it easily online at www.dmaconsumers.org/cgi/offmailinglist. For the junk mail you continue to receive, remember to toss it in the recyling bin instead of throwing it out with the garbage. You can even recycle plastic window envelopes. If all Americans recycled their junk mail, $370 million in landfill dumping fees could be saved each year.
