3CHARACTERISTICS OF CONSERVATION BIOLOGY
4) Multidisciplinary
1) Focus diversity
5) Science with an Evolutionary Time Scale
2) Value Laden, Mission Driven
6) Adaptive legally empowered
3) Advocacy/Crisis Oriented

4I. Ethics -Study of Moral Phenomena . . .
- Moral phenomena
- Moral considerability - what deserves moral
consideration - Moral Values -
5Value basis for an estimation of worthEthics
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.
6II. 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
7A. INSTRUMENTAL VALUE
i.e. Frog secretions block HIV infections
Help from a friend? Antimicrobial peptides
secreted by a variety of frogs prevent HIV
infection. http//exploration.vanderbilt.edu/news/

9A. INSTRUMENTAL VALUE cont.
1. Goods - - direct economic benefits derived
from uses of individual species
2. Services - indirect economic benefits derived
"free" from functioning ecosystems
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.
10A. INSTRUMENTAL VALUE cont.
1. Goods - - direct economic benefits derived
from uses of individual species
2. Services - indirect economic benefits derived
"free" from functioning ecosystems
3. Information - content of the genetic code
represents a resource of knowledge
11Total Economical Value of an Ecosystem
- USE Values
- Direct Use (commodity values)
- Indirect Use
- OPTION Value
- EXISTANCE Value

13Tools 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
14Example of CBA for three development options in
Bacuit Bay, Philippines
Development Tourism Fisheries Logging Total
1) Intensive Logging 6 9 10 25
2) Logging Banned 25 17 0 42
3) Sustainable logging 24 16 4 44
Revenues are in millions of dollars over a 10
year period
15WTP (willingness to pay) how much would you pay
for the preservation of a given entity? WTA
(willingness to accept) what would you accept as
compensation for losses suffered as a result of
an activity?
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.
17B. INTRINSIC VALUE
vs.
18B. INTRINSIC VALUE By Whose Philosophy?
Other philosophies on intrinsic value of
biodiversity
Johnson - species best thought of as
"individuals" protracted through space and time
- ecosystems are "superorganisms"
Rolston - individuals have evolutionary goals
- therefore native ecosystems also have
intrinsic value as arenas for evolution
Callicott, Elliot - something has instrumental
value if for its utility (to humans) -
something has intrinsic value if it is valued for
its own sake
Norton - distinction unnecessary -
instrumental value arguments lead to exactly the
same conservation policy

20III. 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
21A. Anthropocentrism
- from Western religious philosophical
tradition
- God pronounced everything to be "good,
assigning intrinsic value to all forms of life - Genesis (215) 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
222). Non-Western Environmental Ethics
Characteristic Islam Buddhism Taoism Confuciansim
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 natures economy Conserve nature to preserve human society
23B. 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
24C. 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

264 Postulates of Conservation Biology
M. Soulé
- 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
