'Almost two-thirds of land in Australia has been modified for human use, primarily for grazing on natural vegetation. Clearing of native vegetation continues to occur for agriculture, plantation forestry, and urban development. Over the past two centuries, as land use has intensified for a growing population in this arid land, vast areas of native vegetation have been cleared or degraded, resulting in adverse affects on biodiversity, soil and water quality and the spread of weeds, feral pests and diseases.
