Kooser follows a plastic bag on its journey from the landfill into the lives of various townspeople. At the landfill, a bulldozer uncovers a yellow plastic bag. The wind grabs the bag and moves it through the air. The plastic bag enters the lives of a can-collecting young girl, a homeless man and a store owner. The author has included a note about recycling plastic bags. This book may stimulate a lively discussion regarding the environmental impact of plastic bags.--Ministry of Education website.
