In service of Earth Day or anytime, why not try GreenDimes.com? This organization, for $4 a month (a little more than the cost of a latte), will reduce your junk mail and plant trees on your behalf.
Less junk mail saves you the aggravation of shredding paper (or it ending up in a landfill). I get to declutter my desk and save trees from being chopped down in the process. This service also helps prevent identity theft, a growing concern for me and my family.
Seedlings are about $4 a month; saplings are $36 (about the price of your online connection); or, if you prefer, a one-time charge of $360 covers you for life (in this case they'll plant 240 trees for you today!). Wow.
I can’t help thinking this organization is providing a win-win solution for us all.
