• Regulate Access To a Resource
• Example;
• FISHERIES, GRAZING LANDS, FORESTRY
• Or Convert to private ownership???

Planetary Management1. We’re in charge,2. There’s always more,3. All economic growth is good,4. Success depends on understanding, controlling, and
managing the earth for our benefit.

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.
