In Family Circle's November 29 issue, writer John Hanc profiled five young adults who are changing the world, one small project at a time. Kristen Powers, 18, cleaned up an abandoned lot and started a community garden in its place. Jordan Coleman (pictured above), 16, created two films that educate his peers about dating violence and staying in school, respectively. Sisters Ritwika, 15, and Radhika Mitra, 19, provide Indian artisans with tools to help them make crafts--and a living. And Adin Lykken, 20, holds road races to raise money to support a local animal shelter. Read about them and learn how to get involved in their causes here.

I find their stories humbling and inspiring. I'd love to hear about other teens involved in similar pursuits. Do you know of any? If so, share their stories below.
