Title: Conservation Values and Ethics
1Chapter 4
- Conservation Values and Ethics
2It is inconceivable to me that an ethical
relation to land can exist without love, respect,
and admiration for land, and a high regard for
its value. By value, I of course mean something
far broader than mere economic value I mean
value in the philosophical sense.

4Environmental Philosophers
- Instrumental Value
- Also called Utilitarian value
- The value something has as a means to anothers
ends - Anthropocentric
- Human-centered
- Biodiversity has a value only as a means to human
ends.
5Environmental Philosophers
- Intrinsic Value
- Also called Inherent value
- The value that something has as an end in itself.
- Biocentric or Ecocentric
- The view that biodiversity is valuable simply
because it exists. - Value independent of human interests.
6Instrumental Value
- Four general categories
- Goods
- Services
- Information
- Psycho-spiritual resources
7Instrumental Value - Goods
- All things we consume are goods
- Food and clothing
- Heat and energy
- Building materials and sites
- Spectrum of consumption is narrow
- Discovery of new goods all the time

10Madagascar Periwinkle
- Cantharanthus roseus
- Used as ornamental in 19th century
- Later developed into treatment for cancer in late
1950s
11Madagascar Periwinkle
- Example of medicinal benefits of biodiversity in
remote areas - Example of anthropocentric value
- Perpetuates the view that biodiversity is only
worthwhile IF it benefits humans
12Instrumental Value - Services
- Photosynthesis
- Pollination
- Decomposition
- Nitrification
13Instrumental Value - Information
- Genetic information
- Potential implications for economics
- Genetically modified goods
14Psycho-spiritual resources
- Value in the beauty, variety, and wonder of
nature and all its parts - Biophilia humans love of living things our
innate tendency to focus on life - Some consider this to be a component of intrinsic
value, rather than instrumental
15REVIEW
- Instrumental Value
- Four kinds
- Goods
- Services
- Information
- Psycho-spiritual resources
16Intrinsic Value
- The value something has because it exists
- Biocentric philosophy adds
- Organisms are self-organizing and self-directing
- Organisms grow up
- Organisms have sense of purpose
17Is it possible for something to have both
intrinsic and instrumental value?
18Philosophies converge
19Distinct Philosophies
20Monetizing Biodiversity
- Valuing biodiversity in terms of dollars
- Already occurs
- Sources of food/materials have market price
- Travel cost method
- Contingent valuation
- Existence value
21Monetizing Biodiversity
- Ecosystem services
- Cleaning the air, pollinating flowers, etc.
- Costanza et al. (1997)
- Calculated 33 trillion/yr for 17 ecosystem
services - GNP of countries 18 trillion
- Likely underestimation
22ESA Monetization
- 1978 Amendment and God Squad
- Can approve projects that impact species if
benefits are great enough - CBA Cost-benefit analysis
- SMS Safe Minimum Standards
- Assumption biodiversity should be conserved
unless the cost of doing so is high
23CBA vs. SMS
24Conservation Ethics
- Constrains self-serving behavior in deference to
some other good
25Anthropocentrism
- Human-centered value system
- Biodiversity value to humans
- Also, human activities affect other humans
- Intergenerational equity
- The idea that our activities should consider
future generations when determining
sustainability
26Conservation Ethics
- Judeo-Christian stewardship
- Older view held mans dominion over nature
- Later interpreted as stewardship
- dress it and keep it
- Gods view that life on earth is good
27Islam and Biodiversity
- No distinction between religion and secular law
- Koran advocates both instrumental view of natural
resources with a responsibility to stewardship
28Hinduism and Biodiversity
- All things belong to one being Brahman
- All life forms share the same essence
- Inspiration for romantic-transcendentalist
movement
29Jainism and Biodiversity
- Views all living things as possessing an
immaterial soul - Advocates ahimsa non-injury of all living things
30Biocentrism
- Describes nature having an intrinsic moral worth
- Universal concept outside of cultural and
political definitions - How is moral worth decided?
- Rational thought?
- Sentience?
- Inherent worth?
31Biocentrism
32Ecocentrism
- Focuses on the community, rather than individuals
or humans - Responsibilities flow through family units to
global communities - A thing is right when it tends to disturb the
biotic community only at normal spatial and
temporal scales. It is wrong when it tends
otherwise.
