An ecosystem is a community of living organisms and its environment in which there are numerous dynamic interactions. A sustainable ecosystem has the capacity to survive and support itself into the future. Ongoing survival is ensured by a high level of complex interactivity and biodiversity. It is generally accepted that before European arrival, Aboriginal and Torres Strait Islander people lived and used their natural ecosystems in a sustainable way. Billabong managementIn this video, Ben Flick discusses how the Aboriginal people of the western catchment used billabongs in a sustainable way. |
Australian ecosystems changed over time as a result of traditional management and climate change. Some organisms, such as the megafauna, became extinct, but generally the complex interactions and level of biodiversity did not greatly alter for over 60 000 years. Student task |
