Environmental impact of mining can occur at local, regional, and global scales through direct and indirect mining practices. Mining can cause erosion , sinkholes , loss of biodiversity , or the contamination of soil , groundwater , and surface water by chemicals emitted from mining processes.
Sand mining is a direct cause of erosion, and impacts the local wildlife. [6] Various animals depend on sandy beaches for nesting clutches , and mining has led to the near extinction of gharials (a species of crocodilian ) in India .
The environmental impact of mining includes erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater and surface water by chemicals from mining processes. In some cases, additional forest logging is done in the vicinity of mines to increase the available room for the storage of the created debris and soil.
Over two decades, dredging ships have sucked massive amounts of sand from the bed and shores of Poyang Lake in the eastern Chinese province of Jiangxi, drastically altering the ability of its ...
Soil contamination, soil pollution, or land pollution as a part of land degradation is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste .
Environmental geology has reduced the negative environmental impacts of mining as it has been used in litigation toward mining. In some countries like Brazil [8] and Australia [9] for example, it is decreed by law that sites must undergo rehabilitation after a mining operation has ceased. Prior to any mining, an assessment is also necessary to ...
Soil particles picked up during wind erosion of soil are a major source of air pollution, in the form of airborne particulates—"dust". These airborne soil particles are often contaminated with toxic chemicals such as pesticides or petroleum fuels, posing ecological and public health hazards when they later land, or are inhaled/ingested.
Last year, the World Bank approved a $73 million grant to help the Congolese government study the dam’s environmental and social impact. The dam, known as Inga III, would produce an enormous amount of energy in a country where there is almost none. But environmental experts say mining companies and aluminum smelters would be the main ...
