In the 1980s, the mining industry became increasingly influenced by public concern for the quality of the environment. With the rising awareness that preservation of natural features such as scenery and plant and animal habitats had a value to society, governments increased the controls on discharge of potentially polluting emissions such as water containing sediments or chemicals, and noxious gases.
The industry was increasingly being required to justify its activities in competition with other potential uses of the land. Government environmental impact assessment processes took account of the likely effect of proposed projects on the surroundings before deciding whether they should go ahead. Many mined-out areas were now required to be rehabilitated by reshaping and revegetating the surface so that the site could be used for other purposes. <em
