Why do we say that "burning of fuels" can cause ' health hazards' ?
​

Answer 1

Answer:

Burning of fuels causes very serious health hazards and affects all the living organisms. Burning of fossils produces very dangerous gases like carbon monoxide, sulphur dioxide, etc, which affects the bodies of living organisms. Long exposure to such gases can cause lung cancer, asthma, etc.

Burning of fuels can cause ' health hazards' :-

• Fuels, like wood, coal and petroleum products, release unburnt carbon particles. These carbon particles. These carbon particles of smoke, or ash, get suspended in the air. Excessive amount of these particles in the air causes breathing problems. In winter, these particles produce 'smog' which is very harmful to plants as well as animals.

• Incomplete combustion of carbon fuels results in the formation of carbon monoxide gas. It is a very poisonous gas. Even small amounts of carbon monoxide, in air, can cause breathing problems; large amount of it can prove fatal.

• Combustion of fuels releases carbon dioxide in the environment. Excess of carbon dioxide, in air, can trap heat energy which can raise the temperature of the earth. This is termed as global warming. This can result in the melting of polar glaciers, which, in turn, can lead to a rise in the sea level, causing floods in the coastal areas.

• Burning of coal and diesel release sulphur dioxide gas. It is an extremely suffocating gas. It also dissolves in water vapour to produce sulphuric acid. When it rains, the acid, thus produced, can damage buildings, plants and trees. Such rain is called acid rain.
