Australia is battling water and air pollution caused mainly by mining

Explanation:

Mining, the process of mineral extraction from soils and rock formations, is one of Australia's basic economic sectors. However, as with all natural resource exploration, mining activity causes impacts on the environment, with water and air pollution being the main environmental impacts perceived in Australia.

Air pollution is mainly caused by dust, which comes from drilling work and the stages of processing and transportation of material. This dust stays for many hours in suspension and spreads over long distances. Although not very significant, the emission of gases also contributes to air pollution. These gases come from the burning of fuel from machinery and vehicles.

Pollution of water resources (surface and groundwater) by the chemicals used in mineral extraction also causes the sedimentation and pollution of rivers by improper disposal of the unused material (rocks, minerals and equipment damaged) and fish mortality in areas of rivers polluted by chemical elements from mines.
