Africa

You can’t turn on the television or flip open a magazine these days without encountering an image of a star promoting his or her latest cause célèbre: Oprah handing out makeup kits at a women’s hospital in Ethiopia; Angelina Jolie visiting refugee camps (alone or with Brad Pitt); George Clooney zipping around in his tiny electric car and making speeches about Darfur; Jay-Z and Kofi Annan holding a press conference about global water issues; Madonna performing concerts against a backdrop image of aids orphans—and, more recently, bringing a motherless Malawian boy home with her after making a large donation to his orphanage.
