How Does Coal Mining Affect the Environment?
Coal mining affects the environment in several ways: underground coal mining introduces toxins such as methane gas into waterways and the atmosphere, and surface coal mining contributes to deforestation and erosion. Coal mining displaces large amounts of water, which in turn alters local water tables. This change affects organisms in surrounding ecosystems, changing the flow rate and volume of wat.
