Classifying Environmental Values
Pearce and Moran outlined the following method for classifying environmental uses:
- Direct extractive uses: e.g. timber from forests, food from plants and animals
- Indirect uses: e.g. ecosystem services like flood control, pest control, erosion protection
- Optional uses: future possibilities e.g. unknown but potential use of plants in chemistry/medicine
- Non-use values:
Bequest value (benefit of an individual who knows that others may benefit from it in future)
Passive use value (sympathy for natural environment, enjoyment of the mere existence of a particular species)

Famous quotes containing the word values:
“The values by which we are to survive are not rules for just and unjust conduct, but are those deeper illuminations in whose light justice and injustice, good and evil, means and ends are seen in fearful sharpness of outline.”
—Jacob Bronowski (1908–1974)
