You can watch a video and earn money for a charity. Really, it's true. Snopes says so. It was inspired by the song of the same name, What Kind of World Do You Want? by Five For Fighting, one of my favorite bands. (The last CD I bought is one of theirs, and in fact, it's the only CD I've bought in years. Pretty sad reflection of my musical interest, except that I understand CDs are very last century.)
So go save the earth, save our children, or save water.
