According to GreenDimes, a company that prevents paper junk mail and unwanted catalogs, over 100 million trees and 28 billion gallons of water are wasted annually on US junk mail alone.

What GreenDimes aims to do is cut 90% of this unnecessary mail and plant 5 trees per member. For those of us that look forward to J. Crew's merino colors for fall and Pottery Barn's latest entertainment solutions, there is a Catalog Screener where members can opt out of only the catalogs they want stopped (there are 3,000 in total).

The lifetime fee is $20, and if you create a GreenDimes account and refer friends, you get a $3 Referral Bonus for every person who signs up for a GreenDimes service. For the GreenDimes blog, click here.
