India’s Supreme Court has ordered offices in the capital New Delhi and nearby cities to close and asked millions of people to work from home as the cities are experiencing hazardous air pollution.

Officials in the Indian capital closed all schools for four days as an emergency measure to reduce the toxic haze that has been hitting the cities since November.

The court has also ordered the halt to unnecessary traffic, industrial pollution, and dust.

In the meantime, the court also sought urgent steps to prevent crop waste fire in the neighboring states of Haryana, Punjab, and Utter Pradesh that is every year set by hundreds of thousands of farmers looking aimed at clearing fields for a new sowing season.

Burning crop waste has still been the biggest cause of air pollution in India that is not addressed despite spending billions of rupees to tackle the problem.

The air pollution that every year at its deadly level reaches 500 which can cause severe breathing problems if not tackled.
