Chapter 9 · Resources & Human Decisions

Assigned readings

This chapter follows the question: How can people make informed choices within Earth’s limits?

This week’s goals

Read A design decision that people can inspect and revise before starting this chapter. Use the linked unit explanations and source records during the assigned sessions.

Five flexible sessions normally about 45 minutes. Assessment slots explicitly combine or extend sessions to the existing paper’s full time. Slow down and use consolidation sessions for reteaching when an explanation is not secure.

Session 1 · Natural Resources: Renewable & Nonrenewable — observe and build

Illustrative evidence case. A device reduces input per use by 20%, but the number of uses rises from 100 to 130. A renewable stock also loses material faster than it is replenished.

Your task

Read the chapter context and the unit language notes. Make a first model, study the core explanation and Parts 1–2, and attempt their visual and reasoning checks.

  1. Read the assigned context and note two observations.
  2. Draw a first explanation with one uncertain feature.
  3. Study Parts 1–2 and trace each diagram label.
  4. Attempt checks before consulting guidance and record one revision.
Hint and response guidance

Read the stated evidence and diagram captions; separate quantities, reference frames and assumptions before deciding.

Its withdrawal exceeds renewal by 5 units/year. Renewal capability does not guarantee use stays within that rate or conditions remain unchanged. Generation source, conversion/transport losses, materials, use pattern and disposal differ. The full service/pathway must be compared on a common basis.

  • Use the stated evidence and units accurately.
  • Explain a mechanism or evidence relationship.
  • Show a labeled model, graph or intermediate calculation.
  • State a limitation and a useful revision/test.

Session 2 · Natural Resources: Renewable & Nonrenewable — connect mechanisms

A life cycle includes extraction, processing, manufacture, transport, use and end-of-life handling within a specified comparison. Different alternatives can shift impacts between stages. Here the selected single impact metric totals 20 + 15 + 50 + 10 = 95 model units. That total does not combine unrelated quantities such as water, money and greenhouse-gas mass into one physical sum. Use separate indicators or explicitly justified scoring methods when comparing tradeoffs. The same useful service and interval are essential, because a device lasting longer can spread manufacture impacts over more delivered uses.

Your task

Study Parts 3–4 and any source records. Complete the whole-unit application with a labeled diagram, calculations and a limitation.

  1. Define each new quantity and its unit.
  2. Compare the diagrams and stated evidence.
  3. Attempt the whole-unit application without copying guidance.
  4. Check intermediate reasoning and annotate a correction.
Hint and response guidance

Read the stated evidence and diagram captions; separate quantities, reference frames and assumptions before deciding.

A matched boundary and service. Include comparable stages or clearly state omissions before interpreting one total as superior. Total rises from 100 to 104, a 4% increase, despite the 20% per-use reduction.

  • Use the stated evidence and units accurately.
  • Explain a mechanism or evidence relationship.
  • Show a labeled model, graph or intermediate calculation.
  • State a limitation and a useful revision/test.

Session 3 · Natural Resources: Renewable & Nonrenewable — explain and transfer

Use the unit’s worked cases and changed independent application.

Your task

Study the illustrated worked case, attempt practice and the changed case, then revise the opening explanation and complete the exit response.

  1. Explain the worked diagram in your own words.
  2. Attempt varied practice and the independent changed case.
  3. Check evidence/calculations using the rubric.
  4. Return to the first model and explain a revision before the exit response.
Hint and response guidance

Read the stated evidence and diagram captions; separate quantities, reference frames and assumptions before deciding.

Net change is −5 units/year, giving −30 over six years and final stock 170. Renewal can be exceeded, and total use depends on quantity of service as well as efficiency; check actual replenishment and withdrawal conditions.

  • Use the stated evidence and units accurately.
  • Explain a mechanism or evidence relationship.
  • Show a labeled model, graph or intermediate calculation.
  • State a limitation and a useful revision/test.

Session 4 · Human Impact & Stewardship — observe and build

Illustrative evidence case. A demand model combines population and per-person use, while runoff changes must be checked under matched rainfall and soil conditions.

Your task

Read the chapter context and the unit language notes. Make a first model, study the core explanation and Parts 1–2, and attempt their visual and reasoning checks.

  1. Read the assigned context and note two observations.
  2. Draw a first explanation with one uncertain feature.
  3. Study Parts 1–2 and trace each diagram label.
  4. Attempt checks before consulting guidance and record one revision.
Hint and response guidance

Read the stated evidence and diagram captions; separate quantities, reference frames and assumptions before deciding.

0.90×1.20 = 1.08, an 8% total increase under the simple average model. Adding −10% and +20% would miss the product term. Nutrient inputs/concentrations, growth/biomass and decomposition indicators, dissolved oxygen through time, and temperature/mixing/flow comparisons. These connect source and mechanism to outcome.

  • Use the stated evidence and units accurately.
  • Explain a mechanism or evidence relationship.
  • Show a labeled model, graph or intermediate calculation.
  • State a limitation and a useful revision/test.

Session 5 · Human Impact & Stewardship — connect mechanisms

Prevention changes a source or activity before an impact occurs; reduction limits an ongoing effect; restoration seeks recovery after disturbance. Each requires a measurable goal. Planting trees counts an action, whereas survival, native diversity, soil function or water-quality indicators assess outcomes. A visually green site may not have restored the earlier ecosystem processes. Compare costs, maintenance, uncertainty and affected groups while keeping different metrics separate. A successful input reduction does not automatically demonstrate full ecological recovery.

Your task

Study Parts 3–4 and any source records. Complete the whole-unit application with a labeled diagram, calculations and a limitation.

  1. Define each new quantity and its unit.
  2. Compare the diagrams and stated evidence.
  3. Attempt the whole-unit application without copying guidance.
  4. Check intermediate reasoning and annotate a correction.
Hint and response guidance

Read the stated evidence and diagram captions; separate quantities, reference frames and assumptions before deciding.

It measures an action. Survival, appropriate species, biodiversity, soil/habitat functions and other goal-linked outcomes need monitoring over time. They affect runoff independently of the intervention. Without those conditions, a lower measured volume can have another explanation and the change cannot fairly be assigned to the design.

  • Use the stated evidence and units accurately.
  • Explain a mechanism or evidence relationship.
  • Show a labeled model, graph or intermediate calculation.
  • State a limitation and a useful revision/test.
