Gr 5-8-An introductory volume for students investigating the concept of responsible travel to natural areas. Parks informs readers about ecosystems and how they can be preserved. The underlying assumption is that knowledge will lead to understanding and thus preservation. Four chapters explain these concepts and trace the roots of ecotourism citing global examples, international organizations that encourage the practice, how indigenous peoples benefit from it, the advantages to wildlife, and its future. The text also points out the downsides that include introduction of alien species, crowding, and pollution. Full-color photographs enhance the text.-Patricia Ann Owens, Wabash Valley College, Mt.
