Unit 6 Global risks: Environmental risks and resilience
14 revision questions with answers for Unit 6 Global risks: Environmental risks and resilience, marked HL. Read them here, or play the set as a class game on the projector. Free to host, and students join with a code.
Contamination from one country that crosses borders to harm others, e.g. haze from forest fires?
- Transboundary pollutionRight answer
- Point-source pollution
- Diffuse pollution
- Thermal pollution
What this set covers
Shared environmental problems and ways of coping with them are covered. Transboundary pollution, the global commons, the tragedy of the commons, acid rain, the precautionary and polluter pays principles, crowdsourcing, microplastics, social capital and remote sensing appear.
- Common mix-up
- Students often mix up the precautionary principle and the polluter pays principle: one is about acting before evidence is complete, the other about who bears the cost of damage.
- Revision tip
- Apply the tragedy of the commons to the high seas or atmosphere, and write which of the set's governance ideas could reduce the overuse.
