Sebastian Jenal, better known as Özi, is a cartoonist and environmental activist. He's initiated the "Bonn Climate Ambassador" program to get young children interested in protecting the environment.
His comics are printed in a school magazine that's distributed to primary schools across Bonn. It them, his heroes explain what the Greenhouse Effect and climate protection are all about. And each year hundreds of the western German city's students become proud owners of what's known as a "climate license". For more go to http://www.dw.de/program/global-3000/s-11487-9798
