easy way to do something good

i just heard about this a few days ago on npr...clicking on web pages that support different causes, such as protecting land in the amazon rainforest, or support for the breast cancer research fund. all you do, literally, is click on the links provided at the site (care2.com) and they do the rest - no cost to you except a few seconds. i'm bookmarking it and will try my best to save as much rainforest land as i can by clicking on the site each day i'm on the computer. the link is here.
