According to the World Health Organisation(WHO), air pollution kills an estimated seven million people worldwide every year. The same data shows that 9 out of 10 people breathe air that exceeds WHO guideline limits that contains high levels of pollutants. These deaths occur as a result of increased mortality from stroke, heart disease, chronic obstructive pulmonary disease, lung cancer and acute respiratory infections.

India faces a severe Pollution problem. According to a World Air Quality report from Bloomberg, 6 of the top 10 most polluted cities in the World are in India. The report also stated that New Delhi has the worst air pollution of any capital city, a damning indictment of the country’s problems with pollution.

Air pollution is a big problem in India – researchers say it kills more than 1 million in the country each year. On average its cities exceed World Health Organization (WHO) guidelines for the amount of particulate pollution (PM2.5) in the atmosphere by a whopping 500%, according to the report.

New Delhi’s problems are caused by fumes from its sclerotic traffic and worsened by diesel generators and the burning of fossil fuels in cooking by the less-well-off families. Industry plays its part too, as does the burning of waste and farmers setting fields alight after crops are harvested.

Future

On the bright side, country is making some progress, thanks to its National Clean Air Program which is aiming to reduce its air pollution levels by up to 30% by 2024. India is also planning the world’s largest expansion of renewable energy by 2022.
