Question

Write two important causes of air pollution.

Explain any three factors responsible for air pollution. 

Answer 1

1. Vehicle Emissions: Smog and respiratory issues are caused by the discharge of toxic gases like carbon monoxide and nitrogen oxide by cars, trucks, and buses.
2. Deforestation: Cutting down trees reduces oxygen production and increases CO₂ levels, worsening global warming.
3. Burning of Fossil Fuels: Burning coal, oil and gas for cooking and electricity releases greenhouse gases that exacerbate global warming.
