Hi, coal is an organic material like oil . It consists basically of carbon C, hydrogen H, oxygen O and many impurities.
Actually coal is one of the most impure of fuels. Its impurities range from trace quantities of many metals, including uranium and thorium, to much larger quantities of aluminum and iron to still larger quantities of impurities such as sulfur. Products of coal combustion include the oxides of carbon, nitrogen, and sulfur; carcinogenic and mutagenic substances; and recoverable minerals of commercial value, including nuclear fuels naturally occurring in coal.
Coal ash is composed primarily of oxides of silicon, aluminum, iron, calcium, magnesium, titanium, sodium, potassium, arsenic, mercury, and sulfur plus small quantities of uranium and thorium. Fly ash is primarily composed of non-combustible silicon compounds (glass) melted during combustion. Tiny glass spheres form the bulk of the fly ash.

The toxins WILL cut back...... because woodland will disappear, all the oil and mineral factors will be drained. via grasping men that saved on destroying our organic factors. once the oil provide will vanish, men will go back to the primitive lifestyle, till eventually the earth will run dry and timber will be used as fuels. And the destiny era will wade through from the incorrect doings of the present era. i wish and pray that extra human beings will connect collectively to make this international a extra effective position for the destiny generations.
