• Regulate Access To a Resource

• Example;

• FISHERIES, GRAZING LANDS, FORESTRY

• Or Convert to private ownership???

Environmental Wisdom1. Nature’s in charge,2. Some things are limited,3. Technology and economic growth can be bad,4. Success depends on learning how the earth adapts and

integrating how nature acts in to how we act.
