In the spirit of international mindedness (Earth Overshoot Day, http://www.overshootday.org/, was on August 13th this year!), do all you can to avoid waste-of electricity by turning off unnecessary lights and closing all doors; of paper by printing on used paper or both sides and recycling mindfully; of water by turning off the tap when you finish and taking shorter showers in school; of food by eating everything on your plate. Why not start the new school year off in a greener way, and persuade others too? It’s very easy.
