Bono is adding one more award into his collection. Not for his music work, but for his social work. The rocker and activist accepted the Liberty Medal on Thursday night September 27th for his humanitarian work in Africa, exhorted Americans to keep working to solve the world's problems and spoke of those who are without freedom.

Bono and Debt AIDS Trade Africa organization received the award from former Liberty Medal recipient Pres. George H.W. Bush at the National Constitution Center. In addition to the award, there's also a $100,000 prize, which Bono said will be donated to the organization. Ngozi Okonjo-Iweala, former finance minister of Nigeria who sits on the group's policy advisory board, accepted the award for the Washington-based group.

"When you are trapped by poverty, you are not free. When trade laws prevent you from selling the food you grew, you are not free," the U2 frontmant said in a statement upon receiving the honor. "When you are a monk in Burma this very week, barred from entering a temple because of your gospel of peace ... well, then none of us are truly free."

Debt AIDS Trade Africa is an organization Bono helped co-founded in 2002 and is aimed to work with religious groups on global disease and hunger issues.
