Sir: How can we survive during the excessive electricity shortage in the severe heat in Karachi city? This power outage is unbearable. No one is taking notice even though this loadshedding has been going for a few years and Karachi city suffered a lot in the past especially in the monsoon rains. Electricity crisis will become more serious if the government does not take any steps to end the loadshedding in the city. MUHAMMAD HAIDER Karachi
