Rather than the 25 to 30 chapters found in most environmental science textbooks, the authors have limited principles of environmental science: inquiry and applications to 16 chapters--perfect for the one-semester, non-majors environmental science course. True to its title, the goal of this concise text is to provide an up-to-date, introductory view of essential themes in environmental science along with offering students numerous opportunities to practice scientific thinking and active learning.
