People around the world are reducing food waste, and we take the utmost pleasure in reporting on it. Congratulations to France on their epic sustainability game, by the way. There’s no story about repurposing leftovers, keeping organic materials out of landfills, rehoming leftovers and spreading the good word of mindful reduction that we’re not super-excited about!

If you’re looking to plant a seed of knowledge in your little future food waste reductionists, pick up a copy of British author/illustrator Chris Newman’s The Perfectly Wonky Carrot.
