What are the main environmental concerns associated with fossil fuel extraction methods (coal mining, oil and gas drilling, fracking)?

• A. Habitat destruction, water contamination, spills, methane leaks, air pollution, and subsidence; also seismic activity with fracking.
• B. Only CO2 emissions.
• C. Only noise pollution.
• D. No environmental concerns.

Answer: (A)

Fossil fuel extraction affects land, water, air, and the stability of the ground in several ways across different methods. Coal mining disturbs large areas, destroys habitats, and can destabilize the surface (subsidence). It also exposes and releases pollutants that contaminate water through runoff and mine drainage, and generates dust and air pollutants. Oil and natural gas drilling can contaminate water supplies through spills and improper handling of produced water, release airborne pollutants and methane, and disrupt ecosystems where drilling occurs. Fracking adds the dimension of injecting massive volumes of fluid underground, which can induce earthquakes; it also carries risks of water contamination, methane leaks, and air pollution from associated emissions. When you put all these effects together, they cover habitat destruction, water contamination and spills, methane leaks, air pollution, and subsidence, plus seismic activity linked to fracking. That breadth is why this option is the best fit.
