I've been a fan of Maathai's conservation work for years, so I was delighted to come across this little picture book. It gives a very clear overview of her life and the development of the Green Belt Movement, using simple language suitable for children. Getting kids into conservation early, making them aware of the difference an individual can make, is I think critical for the environmental movement, and this is just the kind of book to inspire them to get out and start planting trees themselves.
