THE VALUE OF BIODIVERSITY

 

CONCEPTS:  Biodiversity has many direct economic values related to species that are bought and sold in the market place (e.g., forest, fishing, and rangeland commodities), and many indirect values such as various kinds of outdoor recreation that do not require direct harvest of species.  By far the most valuable of these indirect economic values are ecosystem services, such as maintenance of clean air and clean water, which have been very undervalued by human societies.  Biodiversity also has ethical values that are not normally considered from the standpoint of economics.
