CAIE IGCSE Biology 20.2.4 Undesirable effects of deforestation
Practise linking forest clearance to biodiversity loss, soil erosion, flooding and CO2 changes using diagrams, data and written explanations.
How this is tested
- explain how loss of roots and canopy leads to soil erosion, leaching and flooding
- link habitat destruction to population decline, extinction and disrupted food webs
- interpret deforestation and CO2 data to identify environmental consequences
