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)

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”

“ 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”
