What is cloud seeding? Discuss its potential role in addressing air pollution in cities like Delhi.

Define clearly: Start by briefly explaining what cloud seeding is — a weather modification technique that induces artificial rainfall by dispersing chemicals like silver iodide or sodium chloride into clouds.
Link to Delhi’s context: Mention how it can help temporarily reduce air pollution by washing away particulate matter and improving air quality, especially during high-AQI episodes.
Add balance: Conclude with limitations and a way forward — it depends on cloud presence, is costly, and offers short-term relief; long-term pollution control needs emission reduction and sustainable urban planning.
