It’s still used by some people to treat psoriasis, but doctors who support tar soap as a treatment are more likely to recommend coal tar soap. Coal tar is a distillation byproduct of coal processing. It’s made of thousands of compounds that may vary depending on preparation.
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).
How is coal formed?
Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
What are the 4 types of coal?
Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite.
