Tree Nation: Reversing Desertification

Tree Nation is smart project whose goal is to plan 8 million trees in Niger. On their site they outline the causes and negative effects of desertification. Beyond the necessity and worthyness of the action, the most exciting thing about Tree Nation is how they’re using technology to engage supporters. By tagging trees and using GPS technology, supporters can select specific individuals locations to help plant a tree and later track back to the tree. It’s poetic, really.
