(i) Natural intervention (two):
- Earthquakes and volcanic eruptions.
- Flooding, drought, erosion or storms.
(ii) Human intervention (two):
- Deforestation and bush burning.
- Mining, dam construction, farming and industrialisation.
(c) Five effects of natural and human interventions on the environment
- Soil erosion and land degradation, for example gully erosion from deforestation and heavy rain.
- Loss of vegetation and wildlife (loss of biodiversity) through clearing, burning and habitat destruction.
- Pollution of air, water and land from industries, mining and waste.
- Flooding and displacement of settlements from heavy rain, dam failure or blocked drainage.
- Desertification and climate change (drought, global warming), plus destruction of property and loss of lives from disasters such as earthquakes and volcanic eruptions.
