Common Property Resources

Recycling/Reuse

Point and Non-Point Sources of

Pollution

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)

Pollution…

Point source vs. Non-

Point Source

Classification including

Concentration,

Composition, Persistence

Degradable vs. Non-

Degradable

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

Root Causes of Environmental Problems

5. Lack of solutions with little emphasis on pollution control and waste reduction

6. Failure to encourage Earthsustaining 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”

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

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
