A gorgeously illustrated picture book that celebrates our connections to nature and to each other while empowering young readers to help protect the earth, from a beloved British poet, musician, actor, and activist. In this powerful love letter to nature, a child who befriends a tree grows up and fights to protect it. With its spare, lyrical text; sumptuous illustrations; and back matter about trees, oxygen, and the carbon cycle, this inviting, inspiring call to save our planet is perfect for Earth Day, and every day.
