One of my favorite charities is Playground Builders. They build playgrounds for children in war-torn areas of the Middle East, providing safe places for children to play. They always use local people in the building process, providing much-needed jobs and injecting money into the local economy. And their own administrative costs are bare minimum. (I know the founder and members of the board of this organization.)
If you feel inclined to donate, a benefactor is matching all funds up to $50,000, but only until midnight December 31st. So your $10 would become $20. You can learn more here: http://www.playgroundbuilders.org/what-we-do
Great way to start a new year!
