Why is coal bad for you?

Emissions from burning coal

Nitrogen oxides (NOx), which contribute to smog and respiratory illnesses. Particulates, which contribute to smog, haze, and respiratory illnesses and lung disease. Carbon dioxide (CO2), which is the primary greenhouse gas produced from burning fossil fuels (coal, oil, and natural gas)

Why does coal burn so well?

“Unlike timber, coal when it gets hot has massive thermal mass which is very hard to extinguish. … Coal, and particularly brown coal, is very reactive to oxygen, and will generate CO2 and that creates heat. As the coal gets hotter it will eventually get to flame temperature and that coal will burn.”

Why is coal bad for the environment?

The burning of fossil fuels releases greenhouse gases into the atmosphere, increasing levels of CO2 and other gasses, trapping heat, and contributing to global climate change. … Coal-fired power plants release more greenhouse gases per unit of energy produced than any other electricity source (1).
