Environment and Society
The Need for Sustainability
2
Key Concepts… Sustainable Systems Resources Biological Diversity
The Earth Community Common Property Resources Recycling/Reuse Point and Non-Point Sources of Pollution
3
Resources… Non-Renewable: Produced over millions of years and are in fixed quantities including: Energy Resources (fossil fuels); Mineral Resources (gold, aluminum, zinc); Non-metallic resources (sand, clay and water Renewable: Inexhaustible supply of resources including: energy (wind, solar, flowing water nrg); Potentially renewable (air, water, soil and biodiversity)
4
Pollution… Point source vs. Non-Point Source
Classification including Concentration, Composition, Persistence Degradable vs. Non- Degradable “The solution to pollution is not dilution”

7
Root Causes of Environmental Problems
Rapid Exponential Growth Population doubled between 1950 and 1997 (by 2014 should be 7.2 billion people) A massive degradation of “life support systems” Poverty – lack of choices and lack of environmental education (this will be discussed more) Use of “quick fix” methods using non-renewable resources
8
Root Causes of Environmental Problems
5. Lack of solutions with little emphasis on pollution control and waste reduction 6. Failure to encourage Earth- sustaining forms of economic development (recycle and reuse) 7. Urge to dominate and manage Nature for our use “Approximately ¾ of the Earth has only 15% of the income and uses only 12% of the resources”
9
Fun Facts “ In all Lesser Developed Countries (LDC’s), 1,000,000 people are added to the population count every four days” “Developed Countries use over 90% of the non-renewable fossil fuel supplies”

Sustainable Societies…
Reduce Waste of Matter & Energy Emphasize Pollution Prevention Improve Recycling Efforts & Reuse Efforts to 60% in Each Community Longer Lived Products Increase RENEWABLE ENERGY SOURCES Better Protect the Earth’s Habitats and Species
15
Sustainable Society 7. Establish a RENEWABLE RESOURCE Balance
8. Value the Importance of Natural Resources 9. “Slow” Population Growth Rates 10. Reduce Poverty and Improve Living Conditions in LDC’s 11. Improve Environmental Education Practices
