Pollution is in the air! According to a WHO survey, Delhi’s air quality is considered to be one of the worst on the globe. The air quality is degrading day by day. And, this has a direct effect on our health. The diseases caused due to the polluted air are, but not limited to, strokes, heart diseases, and lung cancer. Come winters, we’ll be faced with smog, a mixture of smoke and fog, which is hazardous to our respiratory and cardiovascular system. In addition, the stubble burning by the farmers of Haryana and Punjab is only aggravating the situation.

And, since Diwali is around the corner, the rapid increase of cracker bursting in every nook and corner is only adding to the problem. However, according to the latest verdict of the Supreme Court, only green crackers are allowed this time. Perhaps, that will solve the problem a bit.
