Using an ecological framework briefly outline some important current physical conditions and trends in place. Please reference the following: air, water, soil, non-human biota, human population, overshoot, mineral resources, artifact. (~200 words)
- 1. Explain how each element of the ecological framework we present in this course is related to the others. Use all of the following terms: humans, numbers, information (genes, epigenetics, experience, culture, non-culture), environment, artifact, nature, resource, hazard, biotic (other humans, other life) abiotic (air, land, water), lock and key.
- 2. Give specific examples of three resource trends and three hazard trends.
- 3. What are five "peaks" to which we refer with the phrase "peak everything"?
- 4. What do we mean and understand by ERoEI and RRoRI as we use these terms in valuescience?
- 5. What was putative ERoEI for oil extraction in the early 20th century and what is it for tar sands and oil shale c. 2016? (two ratios)
- 6. Have we identified proven energy resources accessible with current technology which have ERoEI comparable to oil in the early 20th century?
- 7. List one or more challenges inherent to calculating and comparing ERoEI.
- 8. What is the minimum ERoEI estimated to be necessary to sustain complex human society?
- 9. What are three aspects of environmental quality that you can use as evidence to support a claim that human population is beyond carrying capacity.
