Air Pollution Crisis in New Delhi After Diwali Festival

New Delhi, India's capital city, has very bad air after Diwali. Diwali is a big festival where people use fireworks. These fireworks make the air dirty.

On Wednesday, the air in New Delhi was the worst of any big city in the world. It was 40 times worse than what doctors say is okay.

The city always has dirty air, but it gets worse in winter. Farmers burn plants in their fields, which adds to the problem.

The government tried to stop people from using fireworks, but many still did. Now, people in the city are having trouble breathing and their eyes hurt.
