Ethics

The philosophy of morality , which is concerned with what is right (good, legal, etc .) and wrong (bad, illegal, etc .)

Ethical principles constrain selfserving behavior in deference to some other good

Value

“Worth in usefulness or importance to the possessor”

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…

Instrumental Value

Costanza et al . (1997, Nature ) provide this list of ecosystem goods & services :

Gas regulation; Climate regulation; Disturbance regulation; Water regulation; Water supply;

Erosion control & sediment retention; Soil formation; Nutrient cycling; Waste treatment;

Pollination; Biological control; Refugia; Food production; Raw materials;

Genetic resources; Recreation; Cultural…

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

Immanuel Kant

(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”

Image from Wikipedia; quote from Kant (1785) Groundwork of the Metaphysics of Morals

Religion-Based Conservation Ethics

Judeo-Christian Worldview

God apparently conferred intrinsic value on every living creature by pronouncing Creation to be

“good” (see Judeo-Christian Bible: Genesis)

Images from Wikipedia

Religion-Based Conservation Ethics

Islamic Worldview

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

Images from Wikipedia

Religion-Based Conservation Ethics

Hindu Worldview

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

Images from Wikipedia

Religion-Based Conservation Ethics

Jaina Worldview

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

Religion-Based Conservation Ethics

Buddhist Worldview

Regards other organisms as companions on the path to enlightenment

( nirvana ), through an explicit ethic of non-injury of and boundless loving-kindness for all beings

Buddhist Worldview

Dalai Lama

(b. 1935)

“Our beautiful world is facing many crises....

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

The most recent spiritual leader of Tibetan Buddhism (retired in March 2011) is arguably the foremost conservationist among the world’s religious leaders

Human enterprise created the modern

Biodiversity Crisis and threatens a vast array of

Ecosystem Services

Why should we care?

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?

Human enterprise created the modern

Biodiversity Crisis and threatens a vast array of

Ecosystem Services

Why should we care?

Ehrlich & Wilson (1991, Science ) provide their threepoint answer…

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)
