Be a Friend to Trees (Let's-Read-and-Find-Out Science, Book & Cassette) Overview
Why should you be a friend to trees?
Trees are a valuable natural resource. People depend on trees for food, and animals depend on trees for food and shelter. But most important, we depend on trees because they add oxygen, a gas we all need, to the air. While trees give us many wonderful products, we must also protect them because we can't live without them.
