Chapter 1 Key Concept Review
1-1 What are some principles of sustainability?
3 SCIENTIFIC principles of sustainability:
1. Solar energy: Energy can be traced back to the original source-then sun.
2. Biodiversity: Variety of genes, organisms, species and ecosystems in which organisms exist and interact.
3. Chemical Cycling (nutrient cycling): Matter cycling through the environment.
3 SOCIAL SCIENCE principles of sustainability:
1. Full cost pricing: including the environmental effects and costs in goods pricing.
2. Win-win solutions: Solutions that benefit both the largest number of people and the environment.
3. A responsibility to future generations: Leave the planet in as good of shape as it is now (if not better)

1-2 How are our ecological footprints affecting earth?
We are living unsustainably.
Pollution is coming from a number of sources.
Tragedy of the Commons pg. 12
Different footprints for different countries.
IPAT: I=Impact of human activities, P= Population size, A= Affluence T= + and – impacts of Technology
Related vocab: environmental degradation, natural capital degradation, point sources, nonpoint sources, pollution
cleanup, pollution prevention, affluence
1-3 Why do we have environmental problems?
Experts have identified several problems-see below (pg 16-20)
1. population growth,
2. wasteful and unsustainable resource use,
3. poverty
4. failure to include environmental costs in goods and services.
We are increasingly isolated from nature. (nature deficit disorder)
People have different views about environmental problems.
1-4 What is an environmentally sustainable society?
More sustainable societies protect natural capital and live of its income.
Meets current needs while considering the future. “Living off the natural income”
