Coal mining harms our lands, waters, and wildlife even before burning contributes to coal air pollution and climate change.
Here are some of the adverse effects of coal mining on the physical environment:
Damaging the land
Companies clear forests and strip away the earth in the process, leaving behind desolate lands incapable of supporting wildlife. Not only is excessive logging devastating for wildlife habitats and their inhabitants, but it also accelerates erosion. Without vegetation to anchor the soil, precipitation can carry away loose topsoil into nearby waterways. The sediment can kill fish and plants as well as clog streams, disrupting their natural flow and decreasing available aquatic habitat.
Polluting water
Beyond headwater stream loss, mountaintop removal has severe impacts on water quality that can persist for decades post-mining. According to a report by the EPA, water quality degradation from mountaintop mines and valley fills can reach levels fatality toxic to wildlife. Valley fills drastically increase salinity and metal concentrations downstream, endangering sensitive organisms such as salamanders and certain fish species.
Threats to biodiversity
Each step of the coal mining process poses threats to biodiversity. Clearing forests for surface mining can fragment critical wildlife habitat, displacing or killing the species that reside there. Valley fills bury headwater streams, which provide refuge for rich communities of aquatic life and support species found nowhere else in the river system. Since these headwater streams also form the foundations of stable river food webs, disturbances from coal mining can trigger cascading effects throughout the entire river ecosystem.
The consequences of coal mining highlight the importance of the renewable energy transition. By supporting policies and initiatives that prioritize renewable energy alternatives, we can mitigate these harms to the environment and wildlife to preserve nature for future generations.
