I recently learned about the Invisible Children campaign through Stuart Delony's excellent blog. The campaign grew out of a documentary made by 3 young men who wanted to do something about the plight of children caught in the middle of the war in Uganda (I have since purchased the documentary to show to my youth group).
The video above describes one way youth can get involved. The Invisible Children bracelet campaign "is a micro-economic program creating jobs for men and women in an otherwise unemployable war area . . . the Bracelet Campaign allows Ugandans living in displacement camps to hand-make bracelets and generate a much-needed income. Eight different colored bracelets are being made, and each is accompanied by a short film told by an invisible child. Each of these extraordinary stories highlights one of the many ways Northern Ugandans have been affected by this unrelenting war."
