Drawing basic comparisons between the structure of trees and humans, Are Trees Alive? describes these living plants, how they exist, grow, draw nutrients and provide habitats for other creatures. The double-page acrylic and gouache illustrations span the fascinating variety of trees found throughout the world depicted with their respective cultures -- the exotic baobab, ribbon gum, coconut, cocoa, kapok and banyan trees as well as the more familiar maple, redwood, pine, birch and aspen of North America. A picture glossary of the trees, including their dependent animals, provides interesting historical and scientific information.
