Prior to the arrival of Europeans, land care was a major purpose in life for Aboriginal people and although their approach was entirely sustainable, they were actively intervening in the landscape. They involved activities such as damming creeks, fire-stick farming and sustainable harvesting methods. (Roberts, 2014) The damming of creeks created natural watering holes for their own use as well as attracting animals to the area, which incidentally resulted in a change in Australian landscape. Fire-stick farming was used to promote the growth of valued plants, with plant species unable to survive fire and declining in numbers, and more resistant species, such as grass trees, eucalypts and acacias, dominating. The Indigenous harvesting techniques were also quite sustainable in conserving resources. For example, women dug some varieties of yams in such a way that a portion which would regenerate was left in the ground. (Williams, 1986, pp. 93-94) Prior to the arrival of Europeans, the Indigenous Australians managed their lands in a way that was sustainable and would ensure biodiversity for the future.

However, they left huge impacts on the environment. Whilst the artificial fertilisers provided extra nutrition and improved yield, it also encouraged weed growth, consequently, causing a demand for herbicides. The use of artificial fertilisers created runoff which entered rivers and contaminated them, killing both aquatic life and the animals which relied on the rivers as their main water source. Apart from contaminating the rivers, they also contaminated groundwater and this greatly changed the pH of the soil in a large area, resulting in the change of soil acidity and toxic water; which was harmful towards the growing native
