That I can do.
Just about every animal rights charity has sent out e-mails asking recipients to purchase some of their merchandise as a Christmas gift, to sign up a friend/relative/acquaintance/co-worker/homeless person to a membership as a gift, or send one of their e-cards. I don't have the coin to do the first two for everyone I would like to, and while many of the e-cards are quite attractive, I'd be concerned about the people I send them to suddenly starting to receive unwanted e-mails.
Environmental Defence takes a slightly different path. They suggest sending a Christmas card to Canada's top 10 greenhouse gas polluters.
Done and done. Ho ho ho!
