What are the disadvantages of burning coal?

Answer 1

There are several disadvantages to burning coal.

1. Even before it is burned, coal mining is a dangerous and difficult job in which people are killed every year, and which often results in black lung disease even for those coal miners who do not die in mining accidents.
2. Burning coal releases several forms of air pollution.
3. It always releases large amounts of carbon dioxide, which is a greenhouse gas that is the major cause of global warming.
4. Some varieties of coal also release significant quantities of sulphur dioxide, which leads to acid rain.
5. Various other impurities in coal, such as Mercury, also are released into the air.
