Each chapter begins with a list of key questions and con-
cepts showing how the chapter is organized and what
students will be learning. When a new term is intro-
duced and defined, it is printed in boldface type, and all
such terms are summarized in the glossary at the end
of the book and highlighted in review questions at the
end of each chapter.
Sixty-sixThinking About exercises reinforce learning
by asking students to think critically about the implica-
tions of various environmental issues and solutions im-
mediately after they are discussed in the text. The cap-
tions of many figures contain questions that involve stu-
dents in thinking about and evaluating their content.
Each chapter ends with a Review section containing a
detailed set of review questions that include all chapter
key terms in boldface (p. 75), followed by a set of Criti-
cal Thinking (p. 180) questions to encourage students
to think critically and apply what they have learned to
their lives.Supplements for Students
