If these facts make you as frustrated as they do us, it's time to do something about it.
Join Young Post's "Waste Not, Want Not" project to help spread the anti-food-waste message. Sign up with a team of four to six people and provide a 150- to 200-word project proposal, explaining how your team might promote food-waste awareness at your school.
We will run a series of workshops this month with organisations on the frontline of the city's food-waste situation, explaining things such as recycling, disposal and carbon footprints.
Once your team has this information, you can put your project into action at your school in whatever format you choose, whether it's a series of posters, a video, a play, a speech or a booklet - there are no limits to how you spread the message.
We'll be publishing details and results of the best projects in Young Post!
