News of war can make children anxious, concerned and upset. This book gently explains how wars come about, how they have changed over time, who's there to help during wartime, what happens when a war is over and how we can all make the world more peaceful. Written in a clear, approachable style, with carefully chosen examples, Why are there wars? is both informative and reassuring.

Internet links suggest positive projects for children, including making origami peace doves.
