Economic Systems
-
Brown Economy: capital $, consumption, more harm to ecosystems
Sustainable Economy: human well-being is important, and so is preserving ecosystems, resources, and services instead of using them for capital.

- Gross National Progress (GNP): sum of all goods/services
- Gross Domestic Product (GDP): GDP-GNP = income not from home
- Genuine Progress Indicator (GPI): environmental economists means of measuring economic process (measures economic sustainability)

Environmental Factors
Biotic & Abiotic Factors
conditions = variable, but not used up ex: temp, salinity, sunlight
resources = consumable ex: water, oxygen, nutrient
Optimal Range: best response occurs for an organism. Range of Tolerance: entire span that allows for growth. Zones of Stress: between optimal range and high/low limits. Limits of Tolerance: high/low ends of range of tolerance
-
Habitat: where species are adapted to living, defined by plant community and physical env. Niche: sum of all conditions and resources under which species can live
Taxonomy
Domain, Kingdom, Phylum, Class, Order, Family, Genius, Species (WRITE G. SPECIES)
Ecology Hierarchy
Species -> populations -> communities + abiotic factors -> ecosystems -> ecotone -> landscape -> biomes -> biosphere
