One Campaign is a global advocacy organization that aims to end extreme poverty and preventable disease, particularly in Africa. Founded in 2004 by Bono, the lead singer of U2, and other activists, it focuses on raising awareness and mobilizing support for critical issues like health, education, and economic development. The campaign works with governments, businesses, and citizens to promote policies that improve the lives of people living in poverty. By leveraging the power of grassroots movements and high-profile endorsements, One Campaign seeks to hold leaders accountable and ensure that resources are allocated effectively to combat global challenges.
