Environmental impacts of mining coal and oil extraction on land and water include which of the following?

• A. Land disturbance, habitat loss, water pollution from runoff, acid mine drainage, oil spills, groundwater contamination, and sedimentation.
• B. Coal and oil extraction have no effect on land or water.
• C. Extraction only disturbs land but not water.
• D. Extraction only causes water pollution but not land disturbance.

Answer: (D)

When coal and oil extraction happen, the impact stretches across both land and water, not just one place. Removing vegetation and topsoil for mining disturbs the land and destroys habitats, and it often leads to erosion and sediment that wash into rivers and streams. In coal mining, exposing sulfide minerals can create acid mine drainage, which lowers water pH and releases metals into groundwater and surface water. Oil extraction adds its own land footprint: building roads, drilling pads, and infrastructure fragments habitats, while spills, leaks, and produced waters can contaminate soils and water bodies. Sedimentation from disturbed land further harms aquatic ecosystems by clogging waterways and reducing water quality. So the most complete description is a set of impacts that includes both land disturbance and a range of water-related problems, such as runoff pollution, acid drainage, oil spills, groundwater contamination, and sedimentation. Other options, which claim there are no effects or affect only one medium, miss how interconnected these environmental impacts truly are.
