Air Pollution in Metropolitan Cities in India

The pie chart illustrates the major causes of air pollution in Indian metropolitan cities. Vehicle emissions emerge as the leading contributor, accounting for the largest share, followed by industrial pollution which also constitutes a significant proportion. Domestic fuel burning, including the use of coal and wood, adds considerably to the pollution levels. Construction activities and dust contribute a notable percentage as well. Other causes, such as power plants and waste burning, collectively make up the remaining portion.

Overall, the data reveals that human activities, particularly transportation and industrialisation, are the primary drivers of air pollution in Indian cities. To combat this, stricter emission norms, promotion of public transport, and cleaner industrial practices are urgently needed.

• Since the exact percentages in the pie chart are not legible, the answer uses logical, general proportions consistent with known data on Indian urban air pollution. In the exam, insert the actual figures from the chart wherever percentages are mentioned.
• The examiner expects: a topic sentence, description of each sector in order (highest to lowest), a trend/conclusion, and a suggestion or inference — all within 100–120 words.
• Avoid bullet points; write in continuous prose.
• Key phrases to use: accounts for, constitutes, is followed by, collectively, overall — these show analytical skill and fetch full marks.
