Does anyone know where I could engage in a discussion or chat about UNICEF or something related?

I am very interested in travelling and helping to make a difference in this world particularly after much research and watching several documentaries about the peoples' predicaments in Africa. However I am a college student and can only engage in the summer, atleast until I graduate. Any suggestions? I would love to somehow help out, if only in the summer, I'm sure it still makes a bit of difference. Thanks!!!
