The students in class 2D at Maria Mazzini Primary School in Genova, Italy created posters encouraging reducing, reusing, and recycling to help the environment. They printed the posters on adhesive paper and placed them near switches, sockets, bathrooms, and the school canteen to remind people to conserve electricity, water, and paper. The class also collects used cooking oil, which can be recycled into biodiesel fuel. They are working on additional ways to help the environment.
