Question

Describe the problem of air pollution in India.

Hint:

Cover sources (vehicles, industry, stubble burning), effects, and government responses.

Answer 1

Step 1: Understanding the Concept:
Air pollution refers to the presence of harmful gases, particulate matter, and other pollutants in the atmosphere in quantities that harm human health, other living beings, and property.

Step 2: Major Sources in India:
Vehicular emissions from the rapidly growing number of automobiles; industrial smoke from factories burning coal and other fossil fuels; burning of crop residue (stubble burning) in states like Punjab and Haryana; domestic burning of fuelwood/coal in many households; and construction dust in expanding cities.

Step 3: Consequences:
Air pollution causes serious respiratory and cardiovascular illness, contributes to smog especially in Delhi-NCR during winter, damages crops and vegetation, and corrodes/discolours monuments (e.g. the effect of pollution on the Taj Mahal).

Step 4: Government Response:
Programmes like the National Clean Air Programme (NCAP), promotion of CNG/electric vehicles, and stricter emission norms (e.g. BS-VI) have been introduced to control the problem, though it remains a major public health issue.

Step 5: Final Answer:
Air pollution in India, caused mainly by vehicle exhaust, industrial and household fossil-fuel burning, and crop-residue burning, has become a severe public-health and environmental problem — especially acute in northern Indian cities in winter — prompting measures like NCAP and stricter vehicle-emission standards.
