Expert-Identified Categories and Details
I. Definition (Total: 8)
-
variety at many levels of life organization
-
species (legal definition)
-
animals
-
plants
-
insects
-
microorganisms
-
genetic diversity, both within and across species
-
distribution of species
II. Source and maintenance processes (Total: 4)
-
evolution
-
over very long time periods
-
continual process of adaptation to existing conditions
-
variety of niches and interactions between existing species create ecosystems which provide the template in which evolution can work; ecosystems = community of life; independent of size scale
III. Value (Total: 8)
-
maintains life
-
without genetic diversity individual species can’t survive
-
creates conditions for continual adaptation; preserves options
-
impacts individuals
-
food, medicine
-
ecological services
-
inspiration — meaning beyond ourselves
-
aesthetics, pleasure
IV. How is it threatened? (Total: 2)
-
pace of change due to human modifications of environment too rapid for species adaptation
-
we are simplifying (reducing variety) without understanding the consequences; e.g., soil modifications (fertilizers, pesticides); genetic modification of organisms
V. Human responsibility? (Total: 3)
-
humans have responsibility to other species because we have the power to influence everything
-
we have laws that reflect this responsibility (Species at Risk Act) and political jurisdictions for different categories of life forms (federal — migratory birds, aquatic life; provincial — terrestrial animals)
-
public organizations express this responsibility — e.g., WWF, Sierra club, justice groups
