Definition from The American Heritage Dictionary (1973)
Instrumental Value
Value that Nature has as a means to another’s
( i.e.
, mankind’s) end
Anthropocentric viewpoint
( i.e.
, from the perspective of
Homo sapiens as “possessor”)

Intrinsic Value
Value that Nature has as an end in itself
Biocentric or ecocentric viewpoint
( i.e.
, from the perspective of Nature as “possessor”)
E.g.
, biodiversity is valuable simply because it exists
E.g.
, non-human species have rights

“Daffodils”
(1804)
I WANDER'D lonely as a cloud
That floats on high o'er vales and hills, When all at once I saw a crowd,
A host, of golden daffodils; Beside the lake, beneath the trees,
Fluttering and dancing in the breeze. Continuous as the stars that shine
And twinkle on the Milky Way, They stretch'd in never-ending line
Along the margin of a bay: Ten thousand saw I at a glance,
Tossing their heads in sprightly dance. The waves beside them danced; but they
Out-did the sparkling waves in glee: A poet could not but be gay,
In such a jocund company: I gazed -- and gazed -- but little thought
What wealth the show to me had brought: For oft, when on my couch I lie
In vacant or in pensive mood, They flash upon that inward eye
Which is the bliss of solitude; And then my heart with pleasure fills,
And dances with the daffodils.

Instrumental Value
Non-material Psycho-spiritual – ( e.g.
, biophilia , as contrasted with biophobia ) aesthetic beauty, religious awe, scientific knowledge, etc .
Material…
Goods – food, fuel, fiber, medicine, etc .
Services – pollination, nutrient cycling, nitrogen fixation, decomposition, etc .
Information – genetic engineering, applied biology, basic science, etc .
Instrumental Value
Daily et al . (1997, Science ) provide this list of ecosystem goods & services :
Production of ecosystem goods (e.g., seafood, wild game, forage, timber, biomass fuels, natural fibers, many pharmaceuticals, precursors of industrial products); Purification of air & water;
Mitigation of droughts & floods; Generation & preservation of soils and renewal of their fertility;
Detoxification & decomposition of wastes; Pollination of crops & natural vegetation; Dispersal of seeds; Cycling & movement of nutrients; Control of the vast majority of potential agricultural pests;
Maintenance of biodiversity; Protection of coastal shores from erosion by waves; Protection from the sun’s harmful ultraviolet rays; Partial stabilization of climate; Moderation of weather extremes and their impacts; Provision of aesthetic beauty and intellectual stimulation that lift the human spirit…

Monetizing Instrumental Value of Nature
Costanza et al . (1997, Nature ) provide this estimate for the value of these ecosystem goods & services :
~ $33,000,000,000,000 / yr
[…and the gross world product (the sum of all nations’ gross national products) is ~ $18,000,000,000,000 / yr]

Monetizing Instrumental Value of Nature
Balmford et al . (2002) refined the estimate of
Costanza et al . (1997) and concluded:
“We estimate that the overall benefit:cost ratio of an effective global program for the conservation of wild nature is at least 100:1 ”

Monetizing Instrumental Value of Nature
…. Generally Ignores Intrinsic Value
(1724 – 1804)
German philosopher – among the most influential thinkers of the Enlightenment
“Everything has either a price or a
dignity [intrinsic value] . Whatever has a price can be replaced by something else as its equivalent; on the other hand, whatever is above all price, and therefore admits of no equivalent, has a dignity”

Religion-Based Conservation Ethics
God apparently conferred intrinsic value on every living creature by pronouncing Creation to be
“good” (see Judeo-Christian Bible: Genesis)

Religion-Based Conservation Ethics
The Koran teaches that Allah (God) calls for man’s stewardship to provide a just distribution of natural resources across generations

Religion-Based Conservation Ethics
All beings are a manifestation of the one essential Being ( Brahman ), so human beings are to identify with & respect other forms of life

Religion-Based Conservation Ethics
Parallel paths of asceticism (eschewing physical pleasure) and noninjury of all living things ( ahimsa ) free the soul from future rebirth in the material realm
Few adherents, but Jainism has great influence, especially in India

It is not a time to pretend everything ´s good”

Ehrlich & Wilson (1991, Science ) provide their threepoint answer…
1. Ethical & esthetic reasons (instrumental & intrinsic value)
E.g
., would you rather live in a world with or without grizzly bears, orchids, and dragonflies?
E.g
., do we humans have the right to drive species to extinction?
E.g., do we humans have the right to leave the world in worse shape for our children and grandchildren than it was in when we were born?

2. Potential for new discoveries (instrumental value)
…in food science, the pharmaceutical industry, and manufacturing owing to the vast riches of genetic biodiversity
3. The economic value of ecosystem services (instrumental value)
