NASA satellite sensors have revealed that ‘Aeresol’ has reached its lowest level in 20 years in North India amid lockdown due to Coronavirus infection. Actually, aeresol is small solid and liquid particles present in the air that reduce visibility and can damage human lungs and heart.

In an unexpected but positive turn of events, NASA has reported that aerosol levels in North India have reached their lowest levels in 20 years, following the lockdown measures imposed due to the COVID-19 pandemic. The drastic reduction in air pollution has been attributed to the widespread restrictions on industrial activities, transport, and construction during the lockdown.

Aerosols are tiny particles or droplets suspended in the air that can have a significant impact on both human health and the environment. These particles, which primarily come from vehicles, factories, and construction sites, contribute heavily to the pollution levels in urban areas, especially in densely populated regions like North India. High aerosol levels can lead to a range of respiratory issues and contribute to global warming by absorbing sunlight and trapping heat in the atmosphere.

According to NASA’s satellite data, the lockdown, which began in March 2020, led to a dramatic decrease in aerosol concentrations, particularly in major cities like Delhi, Agra, and Kanpur.

The data revealed that the aerosol levels in the region fell to their lowest point in two decades. This reduction was primarily due to the shutdown of factories, limited vehicular movement, and the temporary suspension of air travel during the lockdown.

The reduction in aerosol pollution in North India has been hailed as an encouraging sign for the environment. Experts have noted that this temporary dip in pollution levels has provided a rare opportunity to study the impact of reduced human activity on air quality. In cities like Delhi, which are notorious for their high pollution levels, this unexpected phenomenon offered a glimpse of what a cleaner environment might look like if long-term solutions were implemented.

NASA’s Earth Observatory noted that the reduction in aerosol levels not only provided significant short-term benefits for human health but also offered valuable insights into the relationship between human activity and air pollution. The findings suggest that if similar restrictions on industrial and vehicular emissions could be implemented on a larger scale, it could have a lasting positive effect on air quality.

The lockdown-induced drop in pollution also became an international talking point, with environmental groups and activists highlighting the temporary improvement in air quality as a potential blueprint for future environmental policies. As the world grapples with the consequences of climate change, many have called for the lessons learned during the lockdown to be incorporated into future sustainability practices.

Despite the positive impact on air quality, experts also cautioned that the reduction in aerosol levels was temporary. As the world begins to recover from the pandemic, and industries resume full the data collected during the lockdown as a stark reminder of the damage that human activity has caused to the environment and underscores the urgent need for more sustainable practices.

In light of this, environmental advocates have urged governments to consider adopting stricter pollution control measures, such as promoting the use of cleaner technologies, enforcing stricter emissions standards,. They have also called for greater investment in public transport systems.

The global impact of the pandemic has been felt in numerous ways, and while the temporary reduction in aerosol levels offers a silver lining, it also highlights the work that remains to be done to ensure a healthier planet for future generations.
