New Biodiversity Chapter
Chapter 12, “Biodiversity Issues,” discusses how population growth and the ability of people to exploit resources led to current concerns about biodiversity. This important topic is examined at the genetic, species, and ecosystem levels, and the value of biodiversity is described from several points of view: ethics, direct economic values, and services provided by organisms in functioning ecosystems. A discussion of the threats to biodiversity looks at habitat loss, over-exploitation, introduction of exotic species, and control of pest organisms. The chapter ends with an overview of efforts to protect biodiversity, and includes a discussion of legal protection and steps being taken to ensure that sustainable management practices are used to preserve biodiversity.
In-Depth Coverage on Sustainability
Sustainability is a core concept in this text and is covered in several chapters. In chapter 2, sustainability is discussed in the context of ethical considerations. Chapter 3 expands on the idea by looking at the topic from an economic point of view. Sustainability is also discussed in the chapters on energy use, biodiversity, water management, agriculture, and at many other points in the text.
New Feature Examines Environmental Change
When we look at environmental issues in general, we find that the same basic issues exist today as in 1983. Although there has been significant progress toward solving some environmental problems, progress in others has been slow, and new threats or concerns have emerged. To help the reader evaluate progress and recognize how difficult some problems are, we have instituted a new feature with this edition. Each chapter begins with a feature entitled, Past, Present, Future, which shows how specific topics discussed in the chapter have changed over more than 20 years.
New Art Adds Depth and Realism
There are over 40 new figures and tables in this tenth edition, many of which have been drawn in a more realistic, three-dimensional style. Numerous other pieces have been revised to reflect updated data or content.
“Risk and Cost” Chapter Completely Rewritten
Chapter 3, Risk and Cost: Elements of Decision Making, has a new introduction to the topics of risk and economics, a new section on how risk is characterized, and a new table on the causes of accidental death. The chapter now describes renewable and nonrenewable resources, and includes a major section on assigning value to natural resources. There are also greatly expanded sections on deferred costs, external costs, and subsidies.
All New Issues—Analysis Case Studies
Every chapter in the tenth edition features a new Issues—Analysis reading, written to reflect current issues and/or new data pertaining to the chapter subject matter. In addition, there are ten other new readings, chosen to complement new text content.
New Fold-out World Map
This unique, oversized fold-out piece features full-color physiographic and political world maps and allows students to refer to either map while reading, helping them to better understand and appreciate global environmental issues.
Special Introduction to Critical Thinking
In preparation for the critical thinking questions found at the end of every chapter, this important preface to Chapter 1 explains the value of correctly evaluating available information to make informed decisions. Six key characteristics of critical thinking are examined.
Guest Essays Provide Regional Examples
In this tenth edition, each part opens with a new guest author’s essay highlighting an environmental issue close to their home. These articles offer expert insight into problems similar to those in students’ own backyards.
• Part I opens with an essay entitled “Can We Save Both Blue Crabs and Watermen?” which describes the regulation of the blue crab fishery in Chesapeake Bay by looking at a specific problem and the ramifications of regulatory action. Author: Jennifer Rhode, Georgia College and State University
• The Part II opening composition, “Imitating Mother Nature in a Florida Lake,” examines the cleanup of a lake in central Florida and its effects on ecosystems and businesses downstream. This essay is an excellent transition to the chapters in this unit, which provide an understanding of the ecological principles that are basic to organism interactions and the flow of matter and energy in ecosystems. Authors: Blase Maffia and Lisa Ganser, University of Miami
• Part III focuses on energy, beginning with its opening article, “Winds of Change,” which follows the events that led an electric utility that relies on nuclear power to invest in wind power in Minnesota. Author: John C. Cronn, St. Cloud State University
• Part IV begins with the essay, “Natural Community Planning,” which describes a California policy designed to preserve biodiversity. Author: Morgan Barrows, Saddleback College
• The Part V essay, “It Isn’t Easy Stayin’ Clean,” introduces the topic of pollution by tracing the effects of human activities on the Lake Champlain ecosystem, and provides a good introduction to the conflict between human impacts on the environment and efforts to reduce damage. Author: Alan McIntosh, University of Vermont
