Day by day the climate conditions on planet earth is changing. Global warming is causing climate patterns to change. Other Day I read a beautiful quote which says “Pollution- If you Don’t kill it, it will kill you”. The message has a very deep meaning and silently warns us for the future. Even people who are healthy and athletic can be affected by air pollution.

When it comes to the polluted cities, many of the world’s most polluted cities are in India. Out of 100 most polluted cities in the world, India alone contributes 31 cities in the list. The cities are ranked based on PM2.5 particles measurements. PM2.5 particles are air pollutants with a diameter of 2.5 micrometers or less, small enough to invade even the smallest airways. These PM2.5 particles are known to produce respiratory and cardiovascular illness.

Standard index rating for air pollutant is given by Air quality guideline (AQG) from the world health organization (WHO) and it specifies that the ideal  measurement of PM2.5 particles should be 10. Below is the list of top 6 cities in India which are rated as the most polluted cities.
