Delhi is being labelled by the WHO as the most polluted city in the world.

The quality of air in Delhi, going through one of its worst smog spells this season, largely fell in the 'very poor' category with the National Air Quality Index recording 'severe' level of pollutants in areas such as Anand Vihar.

On Prime Time a discussion on the alarming levels of air pollution in Delhi and the surrounding cities and whether governments are doing enough to curb it. While the Delhi government suggesting shutting down schools on days when pollution levels are recorded to be very high, the Delhi pollution board disagreed with the proposal. The unchecked burning of waste, rubber, plastic, paper and leaves especially in poor neighbourhoods during winter increases particulate matter in the air.

The Delhi government has made a surprising decision to counter the capital's deadly pollution problem - to start alternate day car use. It's a decision which, if implemented, may get rid of at least 50 per cent of Delhi's air pollution. Will this be feasible?
