Question

Explain the causes of air pollution and suggest any three measures to overcome it.

Hint:

Less smoke + More green = Cleaner air.

Answer 1

Concept: Air pollution refers to the presence of harmful substances in the atmosphere that adversely affect living beings and the environment. It is mainly caused by human activities and rapid industrialisation. Causes of Air Pollution:

• Industrial Emissions:
  Factories release harmful gases like sulphur dioxide and carbon monoxide into the air.
• Vehicular Pollution:
  Increasing number of vehicles emit exhaust fumes and particulate matter.
• Burning of Fossil Fuels:
  Coal and petroleum combustion in power plants and households contributes significantly.
• Agricultural Practices:
  Stubble burning and excessive use of fertilisers release pollutants.
• Construction Activities:
  Dust from construction sites increases particulate pollution.

Measures to Control Air Pollution (Any Three):

• Promoting Clean Energy:
  Use of renewable sources like solar and wind energy instead of fossil fuels.
• Improving Public Transport:
  Encouraging buses, metros, and carpooling to reduce vehicular emissions.
• Afforestation:
  Planting more trees helps absorb pollutants and improve air quality.
• Strict Industrial Regulations:
  Enforcing emission norms and installing pollution control devices.

Conclusion:
Reducing air pollution requires combined efforts from governments, industries, and individuals to ensure a healthier environment.
