Hyderabad:16.7 lakh people died in India in 2019 because of air pollution accounting for 17·8% of the total deaths in the country (source: The Lancet Planetary Health). Air pollution was the 4th leading risk factor for premature death globally, accounting for nearly 12% of all deaths, with more than 6.67 million in 2019 alone, shows the State of Global Air Report 2020. Each of these deaths could have been averted – and every disease caused by air pollution could have been prevented.
Air pollution is the biggest environmental health crisis we face and the WHO has warned repeatedly that air pollution is an invisible killer. The global death rate attributable to air pollution exposure is 86 deaths per 100,000 people. 92% of the global population lives in places where air pollution levels are above the WHO guideline for healthy air. As we write this article from Lucknow, Air Quality Index here is hovering around 465 (WHO limit is 50).
Air pollution is fuelling epidemics. Of all the deaths caused by ischemic heart disease (the biggest killer on our planet), 20% are caused by air pollution. Of all the deaths caused by lung cancer (deadliest of all cancers), 19% are due to air pollution. 40% of COPD deaths are because of air pollution. Asthma is another condition people suffer from which is seriously aggravated by air pollution. Also, let us not forget that other major common risk factors- tobacco and alcohol use- for these diseases are also preventable. Should not our governments hold Big Tobacco and Big Alcohol liable for the irreparable loss of human life and suffering it has caused?
More alarmingly, climate change and air pollution are closely interrelated, further escalating the economic costs and health hazards for humankind. Yet it does not seem to be invoking governments to act with urgency. Air pollution warrants much more urgency to save lives and help people breathe life, and not inhale the deadly disease-causing polluted air.
MAKE BIG POLLUTERS PAY
The Lancet Planetary Health published earlier this month further states that lost output from premature deaths and morbidity attributable to air pollution accounted for economic losses of US$ 28·8 billion (about INR 2,13,451 crores) in India in 2019 alone. “The states of Uttar Pradesh and Bihar, with the highest economic loss as a percentage of their GDP, had the lowest per-capita GDP among the states of India, indicating that these poor states are most vulnerable to the adverse economic impacts of air pollution” states The Lancet.
With overburdened and appallingly weak health systems in India, and with additional challenges posed by the Covid-19 pandemic, we cannot afford multiple epidemics of preventable diseases. No one should suffer from any disease that is primarily preventable. Likewise, no one should die prematurely from these curable diseases.
