Answer 2

When coal burns in air, the carbon component of the coal comes in contact with the oxygen in the air and releases carbon dioxide CO2 when combined.

This is a major cause of air pollution as a large amount of carbon dioxide in air can increase the heat level in the atmosphere and can lead to several diseases in humans as well as animals. It also harms plants.
