As a parent, I dread Delhi winters, not just because of the cold, but because of the terrible pollution in the air

As a parent, I dread Delhi winters, not just because of the cold, but because of the terrible pollution in the air. We live in the city with the worst air quality in the world. Air quality index is generally Moderate (101-200) between January and September, and then it drastically deteriorates to Very Poor (301-400), Severe (401-500) or Hazardous (500+) between October and December.

It amazes me how year after year, as the winter approaches, there is a huge outcry over pollution in the city and then it dies down its own natural death as the summer returns. There is no urgency to tackle this pandemic!

 

Although some of us are still getting used to wearing masks, to many of us with little children, this is nothing new because our kids have been wearing masks for the past couple of winters. In my son’s Montessori pre-school, it was made compulsory for the little babies to wear masks to school. Back then, it felt like I was entering a science fiction film set every time I would go to school. Little did I know that it would become the new normal soon!

As per the current data, as on November 28, 2020, there have been 1,35,906 deaths due to the coronavirus in India. Globally, there have been 1.45 million deaths. Now, compare this to the deaths caused due to pollution. In 2019, exposures to outdoor high average levels of PM 2.5 caused 9,80,000 deaths in India — nearly 60 per cent of all air pollution — attributable deaths. Globally, there were 4.14 million such deaths in 2019. Even if we were to double the coronavirus-related deaths, they would still amount to just about 27 per cent of the deaths caused due to air pollution in India. Then, why is this pandemic being ignored?

 

Anchor What will it take for the authorities and the government to wake up to the reality of the health risks due to pollution? Is it that the awareness of this epidemic is only with the educated and urbane few, that it will only become important once the vote bank of the poor make it an issue for themselves too?

As per the State of Global Air 2020 report (SoGA 2020) released on October 21, a report published by the US-based think-tank, Health Effects Institute, there were at least 1,16,000 infant deaths due to air pollution recorded in India last year.

For the youngest infants, most deaths were related to complications from low birth weight and premature birth — direct outcomes of mothers’ exposure to air pollution during pregnancy. More than half of the infant deaths were due to PM2.5 in outdoor air and the rest were linked to household air pollution due to use of solid fuels such as charcoal, wood and animal dung for cooking, as per the study that claims to be the first-ever comprehensive analysis of air pollution’s global impact on newborns. There is a growing body of evidence about the link between infant death and air pollution and several Indian and international studies have tried to explain it.

 

In 2019, India’s population-weighted annual average concentration of PM 2.5 was recorded at 83.2 micrograms per cubic metre — seven times higher than the WHO’s safe standards of 10 μg/m3 — and remained highest in the world. (The “population-weighted annual average concentration” is the average level of air pollution to which a country’s population is exposed.)

As per the American Lung Association, children face special risks from air pollution because their lungs are growing and because they are so active and breathe in a great deal of air. Children’s exposure to air pollution is a special concern because their immune system is not fully developed when exposure begins.

 

Just like the arms and legs, the largest portion of a child’s lungs will grow long after he or she is born. Eighty percent of alveoli develop after birth. Children have more respiratory infections than adults, which also seems to increase their susceptibility to air pollution.

Furthermore, children don’t behave like adults, and their behaviour also affects their vulnerability. They are outside for longer periods and are usually more active when outdoors. Consequently, they inhale more polluted outdoor air. They are also closer to the earth, where the pollutants are higher.

As per a study titled “State of Global Air 2019”, the average life of a South Asian child growing up in the current high levels of air pollution will be shortened by two-and-a-half years. This means that a child born today will die 2.5 years sooner, on average, than would be expected without air pollution. That is a really scary prospect, and one that makes me want to leave this city, and country, along with my child. Doing a little bit of research on my own, here’s what I found:

 

  •     Children are more at risk from the effects of pollution since they have faster breathing rates, and their lungs are still developing.
  •     Children exposed to high pollution are more likely to have reduced lung function as adults.
  •     Long term exposure to air pollution may cause asthma and other health risks, including cancer, in children.
  •     Air pollution is one of the leading threats to child health, accounting for almost one in 10 deaths in children under five years of age.
  •     Pregnant women exposed to air pollution can hinder the development of the brain and lead to cognitive problems later in the children.

As per the WHO, in Delhi, poor air quality irreversibly damages the lungs of 2.2 million or 50 per cent of all children. My child and your child could be part of that number! There is no way of sugarcoating this; as a parent, I am afraid for my child.

 

If this is not a national emergency, then what is? Our children are the future, and the future is at stake here!
