Hi Patrick,
Thanks for sharing so many practical ways in which children and schools can work through the sustainable development goal in question. It’s a problem that I would be very conscious of, (from a financial as well as environmental point of view) and I’m sure many people are guilty of succumbing to food waste. Your suggestions offer alternatives to food waste, without placing extra burden on teachers in teems of time, workload, etc. The ‘recycling’ of leftover food for making pies, smoothies, etc. is a great idea. Perhaps a competition could be ran and they could bring in things made from leftovers at home.
