Be A Friend To Trees is a lucid and informative introduction with colored, labeled illustrations for young readers to trees, their structure, and the role of photosynthesis as well as our dependence upon trees. Lauber points out the importance of trees, not only as a natural resource for paper and wood items, but also as conservers of soil and as a fundamental source of oxygen, food and shelter for animals. Children are provided suggestions how to be a friend to trees by recycling, conserving and planting trees.
