After 9/11 Danielle Gram, now 21 and a senior at Harvard, couldn't understand why people from different cultures would want to kill each other. At 16 she cofounded Kids for Peace (kidsforpeaceglobal.org), which tries to inspire kids to work for a more peaceful world. It has 75 chapters in several countries. Members pledge to speak in a kind way, help others, care for the earth, respect people and work together. Gram was not deterred when her only brother was killed last year on a vacation—an apparent murder. "Every single one of my immediate family members has a deeper conviction that nonviolence is the way to respond," she says (Christian Science Monitor, December 27).
