Australia Environment - 2022

GEOGRAPHICAL NAMES 

Environment - current issues

soil erosion from overgrazing, deforestation, industrial development, urbanization, and poor farming practices; limited natural freshwater resources; soil salinity rising due to the use of poor quality water; drought, desertification; clearing for agricultural purposes threatens the natural habitat of many unique animal and plant species; disruption of the fragile ecosystem has resulted in significant floral extinctions; the Great Barrier Reef off the northeast coast, the largest coral reef in the world, is threatened by increased shipping and its popularity as a tourist site; overfishing, pollution, and invasive species are also problems
