Query: Easy read with heartfelt message

After having to pick out a book to read for my environmental science class, I read The Legacy of Luna. In a well-written novel, Julia Butterfly Hill recounts her experience of living in a giant redwood tree for 2 years. The book emphasizes how the logging industry is destroying the forest and causing other environmental problems, including an unsustainable way of logging, sedimentation in nearby streams, and causing destructive mudslides. Overall the book tells Hill's story, struggles of everyday life in a tree and her battle with Pacific Lumber and even other environmentalists. I'd recommend this book to those who care about the rest of humanity and how the environment affects everyone else. It's not Dickens or Hemingway, but it is an easy read with a heartfelt message.
