Sir: Karachi is a big port city and the provincial capital of Sindh. This city has been facing numerous complicated problems directly related to the common people. These include health, education and hygiene/cleanliness and poor law and order besides land grabbing and other crimes. Due to the gravity of the problems, many lives have been lost. Moreover, due to an unchecked influx of population from other cities of the country, the employment sector is under pressure. Many young people who do not find jobs resort to criminal and anti-social activities. Karachi city lacks a proper and modern traffic system due to which traffic jams are rampant in many areas of the city. This results in an increased number of road accidents and loss of precious lives on the one hand and loss of time on the other. Besides, these traffic jams and noise pollution have created many physical and mental health illnesses. Due to the negligence of the concerned authorities, the garbage of the city is being transported in open trucks that causes pollution and spreads diseases. The concerned authorities are requested to start planning a modern traffic system for Karachi like other big cities of the world. SOBH BHATTI Karachi
