These old people learned to live in the inhospitable environment of Australiawith very wee effect. Their major environmental impact was from the use ofcontrolled burning of the land. everyplace the years they had learned the bene accommodate ofperiodic fires to control pests and to clear dust before it accumulated andled to large uncontrolled disastrous fires.

What is compulsory now is thecommitment of people and resources to make it happen.
