Fancy Nancy: Every Day is Earth Day (Downloadable audio file, Unabridged edition)

After learning about being green at school, Nancy decides to teach her family all about respecting the environment. On a trip to the supermarket, she reminds her dad, "Please take note: always bring a tote." When Mom turns up the heat, Nancy tells her, "It's better just to wear a sweater." Nancy knows that she is helping her family do something very important; but will she take her enthusiasm for the environment a step too far?
