Sir: I want to draw the attention of the authorities concerned towards a public grievance. Nobody can neglect the necessity of parks in a city. They provide an area for children to play and for the elderly to pass their leisure time. But it can be seen that Karachi has a small number of such recreational spots. Citizens are denied this basic right. Moreover, greenery is rare in the city, which takes away its real beauty. Municipal bodies must give due attention to this matter. Shagufta Idrees Karachi
