WHO:
Green Dimes, a California-based company that's like a "no call list" for your mailbox.

WHAT:
A $20 subscription buys you freedom from 75 to 90 percent of all junk mail and unwanted catalogs, and the company plants 10 trees on your behalf.

HOW:
The Green Dimes team has relationships with direct-mail distributors; they go through each company's process to remove you from their list.

WHY:
Your mailman will thank you, and so will planet Earth. Since its creation in 2006, Green Dimes has planted 969,115 trees, saved 6.3 million gallons of water used in junk-mail production, and prevented 3 million pounds of credit-card offers, catalogs, and other direct-marketing debris from clogging mailboxes.
