Couple of hours ago, I saw this really interesting website where you can find the pollution levels city by city just by one click.
This site give you a world map with numbers on it and on the top you can find the bracket or category where the pollution limit is mentioned.
My city has 129 AQI level of pollution which is termed as ‘Unhealthy’.
I hope more and more people become aware of their surrounding and start taking action to decrease at least some of the pollution at local level
