Biodiversity. As expressed by Edward O. Wilson:
- Biodiversity maintains the integrity of life known on earth;
- Through medicine, agriculture and economics, biodiversity provides
a range of genetic, biochemical, and physical properties of plant and animal life
that are advantageous to human welfare;
- Biodiversity is worthy of preservation because it represents human
kinship through common living organisms; and
Biodiversity is a source of national heritage, giving historic
importance to place, such as the San Francisco bioregion with its distinctive assemblage
of species of plants and animals.
