Rich vs. poor; environmental justice: relation to environmental issues

Relationship between Indicators of Environmental health and quality of life and income

Optimistic, pessimist views of environmental problems

Worldviews: domination, stewardship, biocentric/ecocentric; why important, basic differences.
