In this research paper major pollution problems faced by Karachi Coastline have been discussed. These are the problems by several reasons e.g., untreated waste and sewage from factories are drained into the sea as well as oil spills from ships and fishing trawlers transiting the port. The shipping industry, through its discharges, water pollution, and possible leakages and spills, impacts on this environment. Toxic effects either direct or indirect by bio-accumulation of oil, DDT, PCB, and various metals; avoidance reaction by fish and shrimp because of poor water quality, distortion of organisms and reduction in their reproduction because of poor water quality and the fact that parts of the mudflat areas are being covered with oil; and increased erosion because dying mangroves can no longer reinforce the banks with their roots. There are some citizen action groups opposing the progress. These were also discussed and at the end some solutions to the problems were presented. If that plan should be followed the whole outlook of the Karachi can be changed.
