The participants will start by building the city of Jerusalem at different periods and choose what they bring into the city. After the game, we will discuss with them the importance of adding green spaces and green lungs in the city. They will get to know one of the projects that expresses this idea in Jerusalem – the struggle for the Deer Valley. We will tell them the parable about Honi the circle-drawer and the carob tree so they should understand that the effort to add green lungs is a struggle for future generations and not just for the current generation. Finally, we will create a mural of Jerusalem that includes green lungs and community gardens.
