As Holiday greetings start to flood your mailbox, you can do your part for the environment by recycling the envelopes, but before you do, cut off the canceled postage stamp. Organizations who collect canceled stamps sell them to collectors around the world, then use the money to aid their cause. One such organization is the Royal National Institute of the Blind in the UK http://www.rnib.org.uk/getinvolved/fundraising/recycle/Pages/used_stamps.aspx .
