Lesson Details
Key learning points
- Global and regional trends show increasing demand for food, energy and water resources.
- Increasing resource demand can be caused by population growth, rising affluence, urbanisation and industrialisation.
- Theories can help to explain relationships between population and resources, e.g. Malthus and Boserup.
Common misconception
Global resources are running out because the global population is rising.
Population growth is just one of many factors contributing to increased demand for resources.
Keywords
