Describe what is meant by the phrase “an environmentally sustainable society” as related to the human
population.
Distinguish between these terms: (a) natural capital & natural resources (b) natural services (c) solar capital
(d) natural capital degradation.
Define and give three examples of environmental degradation.
(a) What is the difference between economic growth and economic development? (b) How is each measured? (c)
Describe two basic ways that economic growth can be accomplished.

What is “culture”? Describe the three major cultural changes that have occurred since humans arrived on
earth. Summarize the general relationship between each cultural shift and the environment with a list of
impacts.
Why has each major cultural change led to more environmental degradation?

(a) What is the Law of Conservation of Energy (1st Law of Thermodynamics)? (b) Why is it important in relation to
environmental science?

*** Be sure you understand the basics of biology and chemistry reviewed on pp. 35-40. Pay attention to the compounds named on p. 38;
you will need to know these.
***Also, get familiar with the summary of nuclear reactions on p. 40. Ask me in class if you need further explanation.
