New Delhi starts car rationing to clean up toxic air

New Delhi is implementing an odd-even car ban from November 4th to 15th to combat severe air pollution, with fines for non-compliance. The air quality index has exceeded 900, far above the WHO's 'severe' threshold of 500. Schools are closed and construction halted. Pollution is worsened by crop burning, industrial emissions, and Diwali fireworks. Weather patterns trap pollutants, with cold air from the Himalayas and wind changes after the monsoon season contributing to the crisis.
