Air quality of different cities were checked. Which of the following type of city will have relatively good air quality?
Trees play a very important role in maintaining a healthy environment around us. They provide us with fresh air which is important for a healthy mind. Air pollution has increased a lot with the increase in the number of industries, flyovers and vehicles because we cut down trees while building them. A city with more number of trees and less number of industries, flyovers and vehicles will have good air quality.
