All the “stuff” that surrounds us has a life cycle: materials are harvested, the stuff is made and distributed, it's consumed and then it gets trashed or recycled. Using the typical contents of a child's school backpack (defined as water, food, clothing, paper, plastic, metals, electronics), this book explores those stages in detail, including lots of ways to reduce, reuse or recycle waste along the way. Children will gain new insight into the routine decisions they make about their own consuming and trashing or recycling practices.
