Thus, the pressure on the environment is still heavy. Industrial mining in Liberia includes gold and iron ore. The mining of these minerals is associated with huge environmental impacts ranging from land form degradation, pollution of air quality, loss of biodiversity, and watercourse contamination.
However, the mines also have significant environmental impacts. For instance, a report released by Michigan's Department of Environmental Quality found that sediment in Goose Lake sediment and in some nearby streams have elevated levels of selenium due to mining. Though essential to life, selenium can be toxic to wildlife in high concentrations.
Positive Effects of Mining. Economic Growth. Mining is a vital driver role of economic growth in numerous countries. Locally, it provides much-needed jobs and investment capital. At the top level, it can drive and define national growth. Some nations depend solely on extracting natural resources like many found in the Middle East.
