Sir: Karachi is considered as the city of light as well the largest city of Pakistan and representing the country. But the people are worried about its lightness, as numerous areas are affected by different kinds of pollution ie dirty water, choked gutter, noise and air pollution etc that are causing different diseases in the city. Irony is that, Karachi is port city where foreigners visit regularly and we give them bad impression. Therefore, the Environmental Protection Agency of Karachi is humbly requested to take action on this actionable issue in order to clean and green the biggest city of Pakistan with prevention of dangerous pollution.
