Delhi, the bustling metropolis of India, is currently grappling with a crisis that is not only hazardous but life-threatening. The World Health Organization (WHO) has classified the city’s air quality as ‘hazardous,’ and data collated by IQAir paints a grim picture of how the levels of PM2.5, a dangerous atmospheric particulate matter, have surged in the last two days. This crisis has sent shockwaves through the city and is indicative of a larger global issue – the profound impact of climate change on public health.
The Silent Killer: PM2.5 and its Consequences
PM2.5 particles, with a diameter of less than 2.5 micrometres, may sound minuscule, but their impact is colossal. These tiny particles can penetrate deep into the lungs and even enter the bloodstream, leading to a range of health problems. The hazardous levels of PM2.5 in Delhi pose a grave threat to the city’s residents. According to the WHO, ambient air pollution was responsible for an alarming 4.2 million premature deaths worldwide in 2019. The situation in Delhi serves as a stark reminder of the severity of this issue.
Immediate Consequences
The crisis has led to severe repercussions in Delhi’s daily life. Schools were forced to close, and non-essential construction activities were banned. Dr. Nikhil Modi, a medical professional at Apollo Hospital in Delhi, highlighted the immediate consequences of the situation. He reported a surge in patients with breathing problems, coughs, colds, watery and irritated eyes, and breathing difficulties. What is most concerning is that people of all ages are affected, emphasizing the indiscriminate nature of air pollution’s impact. In response, Dr. Modi urged people to wear masks and limit outdoor activities to essential ones only.
The Culprits
Seasonal Factors and Human Activities: Delhi’s air quality crisis cannot be attributed to a single factor. Regional officials have identified a combination of factors contributing to this dire situation. Lower temperatures, a lack of wind, and the burning of crop stubble in neighbouring farm states have exacerbated an already critical situation. The annual practice of crop stubble burning releases vast amounts of pollutants into the atmosphere, further deteriorating air quality.
A Global Concern
Climate Change and Public Health: Delhi’s predicament is not unique. It is a microcosm of a global issue that transcends borders and affects populations worldwide. Climate change, driven by human activities, is leading to severe consequences for public health. Rising temperatures, altered weather patterns, and increased air pollution are causing a wide range of health problems, including respiratory illnesses, cardiovascular diseases, and heat-related ailments.
The Need for Immediate Action
The alarming situation in Delhi should serve as a wake-up call for governments, organizations, and individuals across the world. Climate change is not a distant threat; it is happening here and now, with severe consequences for public health. Urgent steps are needed to mitigate the impact of climate change, reduce air pollution, and protect human health. Look at polluting industries, construction activities, vehicular traffic (introduce congestion tax), increase green spaces. Restrict car sales based on number of vehicles per family and parking space availability. Retire vehicles not complying PUC norms. Promote public transportation.
Conclusion
Delhi’s hazardous air quality crisis is a stark reminder of the immediate and deadly consequences of climate change on public health. It is essential for governments, communities, and individuals to take action to curb the emissions that exacerbate air pollution and contribute to climate change. The health and well-being of future generations depend on our collective efforts to address this critical issue. In the Green Chronicles of our planet, the time to act is now.
