Every now and then, advertising helps to accomplish something good. These two sites-- which I ought to post once a month-- are both advertising-supported
First, go to the Animal Rescue site, where you can also click for several other good causes.
Then, Go to Care2's Take Action site, where one click (each) saves big cats, baby seals, the rain forest, the ocean and several more.
Go on, drag these sites to your toolbar and go there every day!
