How human activity can affect the availability and quality of water
Directly
Indirectly
Human use of land and its impact on the environment
Salinity
Cause: Irrigation salinity
Cause: Dryland salinity
Case study - how can salinity be rehabilitated?
Practical investigation of soil erosion
Soil contamination eg heavy metal
The impact of introduced species on the environment
Biotic effects
Abiotic effects
How can human activity upset the balance of ecosystems and favour introduced species
Ways introduced species can contribute to the decline or exinction of native Australian species
Investigation on an example of an introduced species
