Here's something you can do for yourself, fashion and endangered species and land. I have the Animal Rescue site as my home page; if you click on the above image, it will take you to the Rainforest Site, which links from the Animal Rescue site as well. There's also a literacy site, hunger, and some others, all in one place.
They offer all kinds of neat things, including clothing, jewelry and accesories that help these causes. So visit these sites, surf their clothing, etc. items, and link to them on your blogs and websites!
