The aborigines took the migration to Australia from Africa. They were the 'first to enter Asia' 70000 years ago.
Also, they were the first to live in 'Australia' according to a '90' year old 'DNA sample hair'. Current aboriginal population in Australia is 3.1 percent.
Many of those are living in all parts of the world as Australian diaspora.

The answer is B.) The Aborigines. They were the Australian Natives, kinda like Native Americans. The British wouldn't show up for a couple thousand years.
Fertilizers and chemicals are important contaminants of water and enter ground both directly and indirectly. In the case of Karst landscapes, the contaminated water infiltrates into the groundwater through underground streams or percolation.
Oil and gas spills also pose a serious problem for groundwater contamination as they can pollute aquifers near fracking zones and other oil extraction areas.
Animal feces are more of a problem in the modern age due to large-scale commercialized animal farms. Unless the waste from these facilities is controlled, it can runoff into fields and rivers and eventually seep into groundwater reserves.
