Why do we say that ‘burning of fuels’ can cause ‘health hazards’?
We say that ‘burning of fuels’ can cause ‘health hazards’ because
a) Incomplete combustion of carbon fuels results in the formation of carbon monoxide gas. It is a very poisonous gas. Even small amounts of it can cause breathing problems.
b) Burning of coal and diesel releases sulphur dioxide gas. It is an extremely suffocating gas and forms acid with rain water which can damage buildings, plants and trees.
c) Burning of fuels releases carbon dioxide gas which causes global warming. This 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.
