Unit 3 Global resources: Consumption trends and impacts
14 revision questions with answers for Unit 3 Global resources: Consumption trends and impacts, marked SL and HL. Read them here, or play the set as a class game on the projector. Free to host, and students join with a code.
Area of productive land and water needed to supply a population and absorb its wastes?
- Carbon footprint
- Biocapacity
- Ecological footprintRight answer
- Water footprint
What this set covers
How much we use and what it costs the planet is the theme. Ecological footprint, biocapacity, virtual water, the water-food-energy nexus, peak oil, fracking, biofuels, land grabbing and the nutrition transition all appear.
- Common mix-up
- Students often mix up ecological footprint and biocapacity: one measures demand placed on land and water, the other measures what ecosystems can regenerate and absorb.
- Revision tip
- Explain the nexus using one example, such as irrigated wheat, showing how a choice about water changes food and energy. Check your wording against virtual water.
