I recently discovered this fund raiser to help the animal victims of the Deep Water Horizon Gulf Oil Spill:
Many artists from all over are donating sketch cards. You make a $10 donation to Institute for Marine Mammal Studies or International Bird Rescue Research Center, then email Kelly Light (firstname.lastname@example.org) with your confirmation of donation, your name and address, and your choice of card. Then the artist mails you the card. It's a small thing, but at least it's something.
