The Value, Use, and Restoration of Ecosystems - Coggle Diagram

- - - - Ecosystem use–Consumptive: harvest food, shelter, tools, fuel,
      - and clothing
        
        •Common in developing countries and even in rural US–Productive: exploitation for economic gain
        
        •Enormous source of revenue
        
        Protecting ecosystems
        
        • Conservation and preservation are typically
        
        confused but are different–Conservation: management and regulation of
        
        ecosystem use–Preservation: ensure continuity (of ecosystem or
        
        species), regardless of potential utility
  - - - Maximum Sustainable Yield (MSY): highest possible
      - rate of use system can match with own rate of
      - replacement/maintenance
        
        Protecting ecosystems
        
        •Maximum Sustainable Yield (MSY)–Can apply to maintenance of parks, air and
        
        water quality, and soils
        
        •Optimal population
        
        •Precautionary principle
        
        •Common-pool resources may be problem –

        How do we manage land and ecosystems?
