Karachi’s Grevous Pollution of Sea

Significant cause of marine pollution in Karachi harbour is the discharge of industrial waste

Karachi port handles a significant amount of cargo traffic. The port’s industrial and shipping activities generate a substantial amount of waste that is often discharged into the harbour without proper treatment or disposal. This has led to severe pollution of the harbour’s waters, threatening the health of marine life and the people who rely on the harbour for their livelihoods. One of the most significant sources of marine pollution in Karachi harbour is the discharge of untreated sewage. Karachi’s rapidly growing population generates a vast amount of sewage every day, and much of it is discharged directly into the harbour without being treated.

The sewage contains various pollutants such as heavy metals and chemicals that can be toxic to marine organisms and harm the overall marine ecosystem. According to World Wildlife Fund, average daily garbage drain into Karachi harbour estimated 5 to 6 tons.

Another significant cause of marine pollution in Karachi harbour is the discharge of industrial waste. Many industries located near the harbour discharge their waste into the water. The lack of proper regulation and monitoring of industrial waste disposal is a major contributor to the pollution problem. Oil spills are also a significant contributor to marine pollution in Karachi harbour.

The port’s high traffic volume and the transportation of oil and other hazardous materials increase the risk of oil spills, which can have severe impacts on the marine ecosystem. The oil can coat the water’s surface, making it difficult for marine life to breathe and absorb nutrients, and also contaminate the food chain.

The pollution in Karachi harbour has led to a decline in marine biodiversity, with many species of fish and other marine life dying off. This has also led to health hazards for the local population.

Pakistan Navy (PN) plays a significant role in subduing the adverse impacts of marine pollution. PN conducts beach and harbour cleaning activities and tree and mangroves plantations ranging from coasts to margala hills on regular basis. Mangroves make up one of the world’s most unique ecosystems and provide host of benefits. They are valuable breeding and nursery grounds for a variety of fish and shrimp and host a variety of life forms like invertebrates, fish, amphibians, reptiles, birds etc. Above all, mangroves produce oxygen and purify the water by absorbing impurities, harmful substances and help us to breathe clean air by absorbing pollutants. PN launched Mangroves Plantation Campaign in 2016 with a plantation target of one million mangroves. After the success of the campaign, PN regularly undertakes mangrove plantation annually at adjoining areas of its coastal establishments.

In addition, PN conducts regular surveys on the harbour’s water quality, monitoring the levels of pollutants and their impact on the marine ecosystem. It also develops and implements pollution prevention programs to reduce pollution levels and improve the water quality in the harbour. PN collaborates with other government agencies, international organizations, and industry stakeholders to develop and implement pollution prevention strategies. The navy participates in national and international forums to exchange best practices and promote cooperation in the fight against marine pollution. By enforcing regulations, promoting public awareness, conducting research, and collaborating with other stakeholders, PN is working towards protecting the marine environment and ensuring sustainable development.
