4. I. Ethics -Study of Moral Phenomena... Moral phenomena – Moral considerability - what deserves moral consideration Moral Values -

5. Value = basis for an estimation of worth Ethics = systematic organizations of values Community “communities that have strong bonds among their members and clear ethics about their relationship to the land draw on deep wells of social capitol in the form of trust, civic and religious organizations, and traditions.”

6. II. The VALUE of BIODIVERSITY - utilitarian - anthropocentric focus - biodiversity is valued only as serving human self-interests - inherent - boicentric - value as an end in itself - the intrinsic value of nature is controversial

8. A. INSTRUMENTAL VALUE continued

9. A. INSTRUMENTAL VALUE cont. 2. Services - indirect economic benefits derived "free" from functioning ecosystems 1. Goods - - direct economic benefits derived from uses of individual species ‘ Biodiversity contains the accumulated wisdom of nature and the key to its future’ Meadows (1990) 1) In an ecosystem context, the value of genetic variability within a species is defined by its role in supporting complex interactions with other species. Australia, for example, has 15 of the world's 16 species of wild soybean. These may prove to be extremely valuable genetic stock in the future because, unlike current commercial varieties, many of these wild plants have genes that help them resist leaf rust diseases.

10. 3. Information - content of the genetic code represents a resource of knowledge A. INSTRUMENTAL VALUE cont. 2. Services - indirect economic benefits derived "free" from functioning ecosystems 1. Goods - - direct economic benefits derived from uses of individual species

11. Total Economical Value of an Ecosystem USE Values –Direct Use (commodity values) –Indirect Use OPTION Value EXISTANCE Value

13. Tools of economic valuation: – assesses the benefits of a particular action and compare them to the environmental costs of that action –Attempt to translate values associated w/ a decision into a market value for direct comparison – attempts to determine, and maintain some minimum level of renewable resource to regulate activities –Management based on an existence value (e.g. minimum pop. Size of a species) rather than an economic value

16. “In developing ideas about the overall value of biodiversity it has been natural to draw on existing arguments about values of individual species (for review, see World Conservation Union 1980; Norton 1988). Commodity value and other direct use values have intuitive appeal because they reflect known values. But a key problem is that species need to be preserved for reasons other than any known value as resources for human use (Sober 1986). Callicott (1986) discusses philosophical arguments regarding non-utilitarian value and concludes that there is no easy argument to be made except a moral one. Species have some "intrinsic value" - reflecting the idea that a species has a value "in and for itself" (Callicott 1986, p.140) - and there is an ethical obligation to protect biodiversity.”

17. B. INTRINSIC VALUE vs.

18. Callicott, Elliot:- something has instrumental value if for its utility (to humans) - something has intrinsic value if it is valued for its own sake Rolston - individuals have evolutionary ‘goals’ - therefore native ecosystems also have intrinsic value as ‘arenas’ for evolution B. INTRINSIC VALUE – By Whose Philosophy? Norton: - distinction unnecessary - instrumental value arguments lead to exactly the same conservation policy Other philosophies on intrinsic value of biodiversity: Johnson: - species best thought of as "individuals" protracted through space and time - ecosystems are "superorganisms"

20. III. Conservation Ethics Discipline within philosophy that articulates the ethical value of the natural world Arguments for priorities: Each species has a right to exist All species are interdependent People have a responsibility to act as stewards of the Earth People have a responsibility to future generations Respect for human life and concern for human interests are compatible with a respect for biodiversity Nature has spiritual and aesthetic value that transcends its economic value Biological diversity is needed to determine the origin of life

21. A. Anthropocentrism 1) from Western religious & philosophical tradition: God pronounced everything to be "good“, assigning intrinsic value to all forms of life Genesis (2:15) suggest the role of man as a RESPONSIBLE CARETAKER AND STEWARD, rather than a tyrant objective intrinsic value of nature by divine decree. species ("kinds") are the focus of intrinsic value, not individual organisms

Non-Western Environmental Ethics CharacteristicIslamBuddhismTaoismConfuciansim Source of value in nature External (Allah) Internal; Budda-nature Emergent; The Tao Emergent; relational Human attitude toward nature Respect for creation is respect for creator Loving- kindness; solidarity Harmony; cooperation Interrelated; interdependent Conservation practice Conserve resources for future generations Still desires; reduce consumption; contemplate nature Adapt human economy to nature’s economy Conserve nature to preserve human society

23. B. Biocentrism SENTIENCE as the capacity to experience pleasure and pain (Bentham) – how many species are included? *SENTIENCE as a means to an animals’ survival (Goodpaster, 1978) - first biocentric ethic

24. C. Ecocentrism  no single organism is more important than another. Ecocentrism does not even distinguish between animate life and inanimate matter or process. The entire "sphere" of life is important

26. 4 Postulates of Conservation Biology 1)diversity of organisms is good; ‘biophilia’ corollary: 2) ecological complexity is good; corollary: 3) evolution is good; corollary: interferences with processes of adaptation/speciation is bad *4) biotic diversity has intrinsic value, regardless of its utilitarian value; M.
