While the pandemic lockdown has created havoc in our lives and aroused an anxiety as to what our “new normal world” will look like, it has, unexpectedly, provided an opportunity for researchers to examine its impacts on the surrounding environment. The air appears to be cleaner and the soundscape quieter. This cleaner, quieter environment enabled Indrajit Mandal and his colleagues to study the effects of COVID-19 on the environment near the Dwarka river basin in Eastern India after nearby stone quarrying areas were locked down. The data collected after the lockdown were then compared to data collected pre-lockdown.
The results of this study indicated a reduction in particulate matter and noise level. The adjacent river water quality was also found to be improved. The findings on noise demonstrated that “noise level is dropped to <65dBA which was above 85dBA in stone crusher dominated areas in pre lockdown period.” This is indeed a significant drop in noise! In their discussion section, the authors cite studies that have examined the adverse impacts of a higher particulate matter concentration, poorer water quality, and increased noise levels on human health.
This paper concludes by noting that now that we know that a temporary lockdown can improve the environment, we should be encouraged to seek ways to provide for a sustainable environment while still supporting a sustainable economy. This sustainable environment would also benefit other species who share this earth with humans. A “successful control of pollution sources can give a lively earth and it can establish the right to life in our planet earth.”
