Coal mining generates significant adverse environmental impacts. Historically, coal mining has been a very dangerous activity and the list of historical coal mining disasters is a long one. Underground mining hazards include suffocation, gas poisoning, roof collapse and gas explosions.
While it is quite possible to keep coal in the hole and oil in the soil, no government or company can ever ensure that carbon will remain in trees. Forest fires, insect outbreaks, decay, logging, land use changes and the decline of forest ecosystems as a result of climate change are all hard or impossible to control.
