Drastic Changes to India’s Air Pollution During the Pandemic
While the world faced unprecedented lockdowns amidst the coronavirus outbreak in early 2020, many environmental scientists observed significant beneficial impacts the lack of human activities caused on Earth’s natural systems. Urban areas were inhabited by local wildlife species that had not been seen in decades, water resources began to purify and significantly reduce air pollution. India’s large cities are well known for their environmental pollution, and the lockdowns created the opportunity for numerous improvements for India’s atmospheric status.
Air pollution is rampant across India because of its enormous population size and concentrated city infrastructure. Air pollution results from too many greenhouse gases like aerosols, nitrogen, and carbon dioxide collecting in the atmosphere. These gases lead to increased temperatures as they capture and hold solar radiation. They also increase cloud retention of particulate matter that can be detrimental to surface resources and human health.
The World Health Organization’s study of global air pollution indicates it poses a significant health risk, responsible for killing 7 million people a year and impacting many more. The COVID-19 outbreak is only responsible for 2.5 million deaths per year to place that statistic into context. In India, contributing sources of atmospheric pollution include vehicle byproducts, industrial power generation, material kilns, and suspended particulate dust contaminants. A report by IQAir identified the top 10 most polluted cities globally, and 9 of them were in India.
India’s urban areas previously blanketed in smog and pollution experienced substantial reductions, extending views to the horizon in many places. Indians in Punjab could see the Himalayas more than 100 miles away! India’s Central Pollution Control Board found more than 85 cities across India with significantly reduced air pollution in only the first week of the pandemic. The report also measured New Delhi, the capital of India, with a more than a 44% reduction in only the first day of restrictions! It is estimated that more than 90 percent of road and transportation activities across the country were halted at the start of the pandemic.
Restrictions were lifted as the early pandemic lockdowns concluded, and life in India seemed to go back to the levels of pollution it created before. This is incredibly worrying because high levels of pollution in the air can highly damage a person’s health. If pollution levels do not rescind, ailments like headaches, respiratory issues, and virus susceptibility will become rampant. Toxic pollution also increases susceptibility to contracting COVID-19 because of its involvement in damaging respiratory cells, severely impacting at-risk demographics.
Parents are forced to keep children home from school many days throughout the year because the overlying smog is too dangerous to breathe in. This saw many schools respond with waning attendance rates even after restrictions were lifted.
