In the rush to sequester carbon emissions for new coal-fired energy plants, it must not be forgotten that coal mining is a dangerous, unhealthy, environmentally-destructive way of life. Many coal miners die in accidents do to lax safety standards. There is still a risk do to environmental hazards such as breathing coal dust even with protective equipment. Also, mountain-topping is a terrible system of mining where the valleys are filled with the tops of mountains taken off to mine coal. All the vegetation is killed off, the topsoil is buried under mine tailings, and the creeks are blocked up right when people need more clean freshwater, not less. It's awful, selfish, and just plain stupid.
It's also very energy intensive where lots of gasoline the diesel fuel is burned to mine, process, and transport the coal.
