Proof that one person can make a difference.

One day, a lightbulb went off in Jeremy Gilley's head: there should be one day each year when the world stops fighting and celebrates peace. And he did much more than just think about it. He traveled the globe, meeting with leaders such as Kofi Annan, Amre Moussa, Shimon Peres, and His Holiness the Dalai Lama. Jeremy's enthusiasm and tireless efforts convinced the governments of the world to change the UN International Day of Peace from a day that moved each year and didn't actually require anyone to stop fighting into a cease-fire day of nonviolence that would fall on September 21 every year.

This amazing story touches on the causes of war, what would happen on a cease-fire day, ways to promote peace on September 21, and most important, how a single person can make a difference in the world.
