उत्तर
Disadvantages of burning fossil fuels:

The burning of fossil fuels produces large amounts of acidic gases such as sulphur dioxide and nitrogen dioxide. These acidic gases combine with rainwater to form acids such as sulphuric acid and nitric acid. Acid rains have been observed in many parts of the world after the industrial revolution in Europe.

Fossil fuels such as coal leave a lot of ash content after burning. This ash is mostly thrown into rivers, leading to their pollution. Such contaminated water causes serious health problems.
-
The burning of fossil fuels produces smoke, leading to air pollution.
-
The burning of fossil fuels releases carbon dioxide − a greenhouse gas which is the main cause for global warming.
