•   A. Humans have always inhabited both the natural world and the social world.
•   B. Environment:
      1. Circumstances or conditions that surround an organism or groups of
        organisms.
      2. The complex of social or cultural conditions that affect an individual or
        community.

                          HISTORICAL PERSPECTIVE
•   D. Four Distinct Stages
      1. Pragmatic Resource Conservation
      2. Moral and Aesthetic Nature Preservation
      3. Health and Ecological Damage Concerns
      4. Global Environmental Citizenship


E. Pragmatic Resource Conservation
• George Perkins Marsh - Man and Nature
      - Influenced Theodore Roosevelt and Gifford Pinchot.
          1. Pragmatic Utilitarian Conservation
               “Greatest good for the greatest number for the longest time”
               Multiple Use Policies of USFS.
                     Moral and Aesthetic Nature Preservation

        2. Nature deserves to exist for its own sake - regardless of degree of
        usefulness to humans. (Biocentric Preservation) John Muir - President
        Sierra Club
        3. Modern Environmentalism
           • Industrial explosion of WW II added new concerns to the
              environmental agenda.
                Rachel Carson - Silent Spring (1962)
           Environmental Agenda expanded in 1960’s and 70’s to include:
             •
             Atomic Weapons Testing
             Fossil Fuel Issues
             Air and Water Pollution
             Wilderness Protection
     4. Global Concerns
            • Increased technology has greatly expanded international
               communications.
             Daily events now reported worldwide instead of locally or
              regionally.
     - Global Environmentalism
F. CURRENT CONDITIONS
     1. Human Population > 6 Billion.
            Food shortages and famines exist in many densely populated
              areas.
            Water Quantity and Quality Issues
            Fossil Fuel Burning
               - Air and Water Pollution
            Landscape Destruction
               - Loss of Biodiversity


G. Signs of Hope
      1. Progress has been made on many fronts.
            Population has stabilized in many industrialized countries.
            Incidence of life-threatening diseases has been reduced in some
             countries.
            Average life expectancy nearly doubled.
H. RICH / POOR: A DIVIDED WORLD
      • Poor countries tend to be located in Southern Hemisphere.
      World Bank estimates1.4 billion people live in acute poverty of < $1 (U.S.)
         per day.
           Daily survival necessitates over-harvesting resources thus degrading
            chances of long-term sustainability.
                  Poor are often victims and agents of environmental
                   degradation.

         •       Wealthy countries tend to be located in the Northern Hemisphere.
         •       About 1/5 of world population live in countries with per capita income
                 > $25,000.00 (U.S.).
                   Poor people exist here as well.
         •       Gap between rich and poor continues to increase.
                   Wealthiest 200 people in the world have combined wealth of $1
                    trillion - more than total wealth of poorest half (3 billion) of the
                    world’s population.
