This is fascinating theory, but would make sense. I agree that the early settlers, did more harm than good. Not only to the local Aboriginal people, but to the environment.
The early settlers, brought to the continent many diseases, also their livestock, were introduced.
In his award-winning book, Dark Emu, which has inspired a new contemporary dance production at the Sydney Opera House, Mr Pascoe details fascinating journals of the early European explorers.
They describe densely-populated Aboriginal villages up and down the country, some with sophisticated buildings made of large logs and clay plastering.
They also describe how indigenous people produced grain surplus to requirement, stored it and used complex systems to preserve soil, water, wildlife and fish as well as native seeds, nuts, fruits and vegetables.
I wonder if we as Australians, can learn how the early indigenous people, harnessed the land. Making, Australia a better place to live. Increasing the capacity of the environment to better support the inhabitants.
