Nowadays there are many places which have been polluted due to many reasons. People even are cutting trees to build buildings and have wood. Which is not good for us. We need trees for many reasons but one of the many reasons is to have oxygen for breathing purposes or in simple words we can say we need air to survive. Diwali has recently ended and it might have caused lot of pollution due to the fire crackers we burst. We must avoid bursting crackers and use eco friendly ones which cause LESS pollution. Festivals are meant to enjoy not to cause any sort of problem. Save our planet earth!

Let us all celebrate world cities day with many eco friendly things!
