There are tabs for hunger, breast cancer, child health, literacy, rainforest, and animal rescue (although the link goes right to the animal rescue site, you can click on any of the tabs on the top of the page to get to the others). It's free and just one click helps. I found it on facebook lol, but I thought it'd be nice to share because it doesn't take much.
