Air Pollution (what is it and how does it affect me?)

In New Delhi, levels of particulate matter are so high that breathing here is the equivalent of smoking 50 cigarettes a day. In fact (at the time of writing), across the whole of 2021, there has not been a single 24-hour period in New Delhi where the air quality was considered to be at a ‘safe’ level for human health. Cleaning up the air in New Delhi to World Health Organisation (WHO) recommended levels could add an extra ten years to life expectancy in the city.
