  • Environmental Risks of Mining

    Mining, like most heavy industries, is dependent on fossil fuels, which generate the energy needed to operate a mine. To combat these carbon emissions, some countries have enacted regulations requiring emission credits, but many countries do not have codes dealing with carbon output ("Molycorp, inc.," 2010). Some form of environmental standards are needed for larger countries like China and ...
