The burning of fossil fuels has several disadvantages:

A. Release of Harmful Gases: It emits pollutants like carbon monoxide, sulfur dioxide, nitrogen oxides, and particulate matter, contributing to air pollution and health issues.

B. Oxygen Consumption: Combustion requires oxygen, as fossil fuels react with it to produce energy and byproducts.

C. Carbon Dioxide Emission: It releases significant amounts of carbon dioxide, a major greenhouse gas driving climate change and global warming.
