The idea for this project and for the participation with other schools derives from the growing concern about the use of our resources. The Fridays For Future movement has made it clear that one must actively work to change the world and not wait for other people to care. In general our curriculum already contains aspects of sustainability and an ecologically-friendly lifestyle. Through the cooperation and interaction with the other students, they think about and discuss further ways of a sustainable lifestyle and actually do something for our environment.
