Value of Biodiversity
- Greek, they had a natural product, used as a form of birthcontrol (plant called Silphium)
- exchange of goods from where they grew this
- the value of it went up so much that it was engraved on coins etc
- eventually, it went extinct
- the heart of love, comes from the shape of the seed of the silphium
- first plant to be driven to extinction by the use of people
- how dependant we were on it
A. Intrinsic Value
- hard to defend
- independent of any value to anyone or anything
- there is no trade in use of this given organism
- they are just there for thier own sake
Religious biophilia
- religions liek biodiversity
- if God created them, the creatures must have an intrinsic value
- Judeo-Christian world view
- creation is "good", so we shouldnt be distroying it
- North American biophils
- nature has uses otehr than human gain; nature has more value than just what it
can give us
- so away from religion, but intrinsic value
- Islamis world view
- just distribution of natural resources across generations; sustainable way through
generations
- Hindu world view
- Buddhist world view
- all organisms are on thier path to enlightment
- so the largest religions, the care for life is ingraved and should be followed
- instinsic value for conservation; connects to religion (operationallu often based on religion)
- but it often doesnt work to conserve based just on reigion, and thats why govenment steps
in
B. Extrinsic Value
- is very subjective, depends on which side you approach
- one place or thing may have different value depending on different people
- extrinsic value also depends on the circumstances,
Direct-use Value
- we are adding the value to biodiversity
- food, building materials, fuel, paper products, fiber, industrial products, medicine
- how much of nature growing do we actually use?
- NPP-> how much plants grow within one year in the landscape, and how
much we use
- depending on areas, we use 80-100% of what is made (like India)

Document Summary

Greek, they had a natural product, used as a form of birthcontrol (plant called silphium) Exchange of goods from where they grew this. The value of it went up so much that it was engraved on coins etc. The heart of love, comes from the shape of the seed of the silphium. First plant to be driven to extinction by the use of people. How dependant we were on it: intrinsic value. Independent of any value to anyone or anything. There is no trade in use of this given organism. They are just there for thier own sake. If god created them, the creatures must have an intrinsic value. Creation is good, so we shouldnt be distroying it. Nature has uses otehr than human gain; nature has more value than just what it can give us. So away from religion, but intrinsic value. Just distribution of natural resources across generations; sustainable way through generations.
