Pollution Control

CLOUD SEEDING: MEANING , CHALLENGES & WAY FORWARD

Delhi’s air pollution crisis is primarily caused by emissions from vehicles, industries, construction, power plants, waste burning, and seasonal crop stubble fires, worsened by stagnant winter weather. Cloud seeding, which disperses chemicals like silver iodide into existing clouds to induce rainfall, has been proposed as a temporary measure to wash away pollutants. However, its effectiveness is limited, dependent on suitable clouds, and provides only short-term relief. It also raises environmental, ethical, and accountability concerns.
