      SOS Children has brought Wikipedia to the classroom. SOS Children's Villages is an international children's charity, providing a good home and loving family to thousands of children who have lost their parents. We also work with communities to help vulnerable families stay together and raise children in the best possible environment. Why not try to learn more about child sponsorship?
