Judy Moody Saves the World! (Book 3)

Judy's learning about the environment in class. When she hears about the threats to the rainforest and endangered species - not to mention her own family's poor recycling habits - Judy's soon in the mood to whip the planet into shape. She decides that her class needs a way to replace the trees they destroy for pencils. One bottle drive later and they've raised enough money to plant a hundred trees and won the Giraffe award - for sticking their necks out for a good cause!
