In a recent study conducted by researchers at the Indian Institute of Technology (IIT), it has been revealed that the air pollution levels in major Indian cities have significantly decreased during the lockdown period imposed due to the COVID-19 pandemic. The study, which focused on cities like Delhi, Mumbai, Kolkata, and Chennai, found that the levels of harmful pollutants such as nitrogen dioxide (NO2) and particulate matter (PM2.5) have dropped by as much as 50% compared to the same period last year. This significant reduction in air pollution is attributed to the decrease in vehicular traffic and industrial activities during the lockdown. The findings of the study highlight the impact human activities have on the environment and underline the importance of sustainable practices to curb air pollution in India. With the government gradually easing restrictions and allowing businesses to resume operations, it is crucial for policymakers to implement measures that promote clean air and sustainable development. As India continues to battle the COVID-19 crisis, the study serves as a reminder of the positive impact environmental conservation can have on public health. Moving forward, it is imperative for both the government and the public to work together towards building a cleaner and healthier environment for the future generations.
