G. Tyler Miller's worldwide bestsellers have evolved right along with the changing needs of your diverse student population. Focused specifically on energizing and engaging all your students, Miller and new contributor Scott Spoolman have been at work scrutinizing every line--enhancing, clarifying, and streamlining to reduce word density as well as updating with the very latest environmental news and research. The resulting texts are shorter, clearer, and so engaging that your students will actually want to read their assignments. The Fifteenth Edition's engaging, streamlined coverage includes over 4,000 updates and new topics; hundreds of new Thinking About exercises that engage students in critical thinking about environmental science topics; Core Case Studies that reinforce chapter concepts; 127 new photos; and superb, integrated coverage of sustainability! New to this edition for instructors is PowerLecture, a one-stop shop for lecture prep that includes everything you need to create dynamic lectures all in one place.
