My friend Heddy would like to save the world. She works tirelessly at her day job for the human right’s organization Amnesty International and spends her spare time (!) campaigning for another non-profit organization called Rebel Letters. RL aims to meet the urgent need that currently exists to unite the fragmented rebel movement in Darfur. (If you’ve never heard of Darfur, it’s the location of one of the most horrific ordeals taking place in the world today. Trust that Angelina Jolie would fix this problem if she could.) To learn more and to help—all it takes is (you guessed it) a letter—please take two seconds and visit RebelLetters.org. Heddy, Angelina, and Darfur will greatly appreciate it.
