Celebrities have long used their popularity for causes they believe in. In 1984 some of the biggest musical stars in the United Kingdom recorded the song “Do they know it’s Christmas” in an effort to raise money for famine relief in Ethiopia, a drought that killed approximately one million people. The young Irish rock star, Bono, was one of the performers on “Do they know it’s Christmas.” Bono has continued his humanitarian work and is the co-founder of ONE, a non-profit group working to end poverty and support development projects in Africa. With the Horn of Africa fighting a drought and U-N declared famine that experts say is the worst in 60 years, ONE is encouraging world leaders to act quickly to prevent more deaths. From Washington, DC, Julia Laurence reports on the group’s efforts to raise awareness of the drought.
