Me to We is an organization started by two Canadian brothers that work to empower youth to make a positive difference. (One of these brothers was awarded the Community of Christ International Peace Award in 2005). Their organization Free the Children is focused on addressing child labour issues around the world.
Check out these sites for their videos, lesson plans, and other resources that discuss issues centered around Abolishing Poverty and Ending Suffering and Developing Disciples (and Leaders) to Serve in their communities.
These resources and ideas would be great for those of you that lead youth camps or young adult retreats. (Some of the activities might just need to be altered for an older audience. But the ideas are there!)
