Study Guide – Chapter 25 - Environmental Worldviews, Ethics, and Sustainability There are several different environmental worldviews that significantly affect how or if we can conserve the natural resources of the planet. These worldviews depend on people’s environmental ethics , what they believe to be right and wrong with regard to how our actions affect the world we live in. As you can see in Figure 25-2, we can group environmental worldviews into 3 broad categories. The planetary management worldview is probably a dominant worldview among industrial companies in developed countries, i.e., humans should use nature to meet our needs, we can fix all problems, and economies much continue to grow. The stewardship worldview is another human-centered viewpoint that emphasizes “good” management of the world’s resources, environmentally-friendly economic development, and protecting the planet’s life support systems for humans and other living organisms. The environmental wisdom worldview is similar, except that it is not really human-centered, but sees humans as part of nature, not a separate manager of nature. It emphasizes learning how nature works and using these principles as we develop economies based on sustainable use of limited resources (either limited in amount [coal], or limited in quality if not managed properly [water]). Human responses to natural resource problems are diverse; most people believe it is wrong to cause the premature extinction of a species, some because it is a genetically-unique organism shaped by evolution that deserves to exist ( intrinsic value ), and some because it is or might be of economic value now or in the future ( instrumental value ). Some people would also assign an ecological value to an organism, recognizing its role in ecosystem function, what the book calls an earth-centered environmental worldview, and how most organisms contribute to the life- support systems on our planet. Note the eight premises that comprise the deep ecology worldview developed by Arne Ness in 1972: 1. All life has value, independent of its usefulness to humans 2. All life is interdependent and contributes to the success of human and non-human life 3. Humans have no right to negatively affect these natural connections except for vital needs 4. Human interference with ecosystem function is excessive and is increasing 5. A decrease in human population size would decrease our interference with life-support functions
