Stacks of smoke are clouding the skies in Delhi. You see and smell the fumes, feel them in your lungs at every traffic intersection. Carbon emissions are highest when a car's engine is idling, most of the times traffic signals. City's youngsters have now taken it upon themselves to raise awareness about the alarming air pollution in the national capital. Over 100 students gathered at the Moti Bagh intersection on Saturday, urging commuters to 'switch off' the ignition to reduce vehicular emissions.
