STARS WANT TO SAVE THE WORLD
Hollywood stars are beautiful, talented and generous, too. In fact most stars do some work for charity. Today lots of celebrities, like Angelina Jolie, George Clooney, and Scarlett Johansson do charity work.
In Hollywood it is fashionable to be concerned about the world and the environment. But can actors succeed where politicians failed? Well, some are succeeding very well! When a charity is connected to a star, it gets publicity. People become interested and want to help: Angelina Jolie and Brad Pitt are often in the news because of their work for charity. In 2006 when Jolie was expecting her baby, she let ‘People magazine’ print photos in exchange for a donation to a charity in Haiti. ‘We cannot ignore the fact that millions of people are suffering. I want to help’, says Jolie. Here are some celebriies who are trying to make the world a better place.

He made a documentary called Running the Sahara to get support for clean water programs in Africa.
In 2001 Scarlett Johansson didn’t go to the Oscars: she preferred to tour India and Sri Lanka for the charity Oxfam. ‘It is strange to come home when you see people living in poverty’, she says, ‘It’s strange to be famous, but this means I can help a lot of people’.
