Ponheary Ly, CNN Hero, Helps Cambodian Children Go To School

Although school is free across Cambodia, poor children in rural areas are often unable to attend because they cannot afford the necessary school supplies and uniforms.

For Ponheary Ly, the daughter of a schoolteacher who was killed by the brutal Khmer Rouge, helping children attend school is a mission. Ly started by helping one girl, giving her the money she needed for supplies and uniforms. Now, Ly has established her own foundation, helping thousands of children in rural Cambodia go to school. It takes only $20 a year to ensure a child gets an education.

CNN profiled Ly as part of their CNN Heroes series.
