Instructions: It is a straight forward question.
Solution:
Air pollution is the accumulation of pollutants in the air, in sufficient amounts, which can affect human, animal, or plant life or cause discomfort to their peaceful living.
Causes of air pollution:
Excessive use of fossil fuels: The use of fossil fuels such as coal, petroleum etc, on large scale produces several poisonous gases such as carbon monoxide, sulphur dioxide etc., pollute the air.
Unplanned urbanisation: Rapid urbanisation and population explosion put pressure on the environment by clearing forests and cutting down trees for various needs and thereby disturbing the balance of oxygen and carbon dioxide in the atmosphere
Reckless industrialisation: Industries emit harmful gases while burning coal and petroleum for their usual activities. This eventually pollutes the air.
Infrastructure projects: Aects lead to the production of a huge amount of dust and particulate matter.
