CAIE IGCSE Biology 20.3.3 Sources & effects of pollution
Practise linking pollutant sources to acid rain, greenhouse gases, climate change and named ways to reduce air pollution impacts.
How this is tested
- state greenhouse gases
- describe how acid rain damages forests through low pH, leaching and leaf damage
- explain how scrubbers, catalytic converters or reduced fossil fuel use cut acid rain
