Essentials of Environmental Science is ideal for a one-semester course. It takes the same non-biased approach as its parent text, teaching students to think critically about data presented. In addition to being briefer, Essentials is even more accessible placing less emphasize on math calculations. The coverage of ecology, agriculture, energy, and water has also been streamlined to provide a more focused treatment of the science concepts.

Available for the first time with Macmillan's new online learning tool, Achieve, Ecology: The Economy of Nature takes students through all of the key concepts of an ecology course. It challenges them along the way with questions that encourage critical thinking, whether about chapter concepts, quantitative tools, or figures. Achieve for Ecology: The Economy of Nature connects the interactive features and real-world examples in the book to rich digital resources that foster further understanding and application of ecology. Assets in Achieve support learning before, during, and after class for students, while providing instructors with class performance analytics in an easy-to-use interface.
