In the historic fishermen population of Karachi, Ibrahim Haidari, in the lap of fishermen, anchored his boat, pulls out the nets and empties the plastic baskets. One fisherman will get three thousand Pakistani rupees (US $ 30) for three days work, because food-making factories for fish will buy their prey at a lower price than the market price. They have to go out into the open sea in search of prey because there is no prey new sea shore.
The fate of the inhabitants of the oldest fishermen village is left with them as they face the ever-increasing pollution of Pakistan’s largest city; Boats, larger nets and more are needed for them to go in to center of sea. Fish are being badly affected by dumping garbage and sediment into the sea.
A few yards away from the fishermen dock, piles of rubbish have been dumped on the shore. Near the village there is a large dirty drain. The smoky black water drops beneath the white foam into the sea. This poisonous fluid is the product of the city. There are ten thousand industrial units in six industrial areas of Karachi that make everything from textiles to chemicals and paints. Leather dyeing factories are the most polluted in terms of chemical waste.
According to government estimates, Karachi produces about 500 million gallons of dirty water daily. About a fifth of these industries, while the rest from domestic or municipal drainage. “Almost all domestic or municipal and industrial wastewater is not cleaned before becoming a part of the sea, and this is a disaster because it eliminates fish prey. And marine life is also badly affected.
By law, owners of industrial enterprises are responsible for cleaning up industrial waste and disposing of wastewater without damaging the environment, but factory owners differ. Most industries were founded five or six decades ago and There is no room for treatment plants in factories.
The government has plans to clean industrial wastewater, but no progress has been made on it yet. A large treatment plant was started in Korangi Industrial area, but it is no longer working.
Karachi does not have spaces for garbage, so trash or solid waste, including plastic, is dumped directly into the sea or into rain drains, which eventually fall into the sea after the flood of monsoon.
According to Sindh Environmental Protection Agency (SIPA) data from the Provincial Environmental Protection Agency, much of the waste comes from a large local colony of livestock, including about a million animals, including cows and buffaloes. The waste produced here is also dumped into the sea.
Pakistan’s two ports on the same coast, Karachi Port and Bin Qasim Port, also contribute to pollution. The Karachi Port Trust (KPT) ‘s Arbak authority says it is working day and night to keep the sea clean, but according to the Pakistan Game Fish Association, the Karachi port is the most polluted area in the world. Oil spill incidents are commonplace and the 2003 Tasman Spirits oil spill is one of the worst in the world.
A Greek ship called Tasman Spirits near Karachi Port and thousands of tonnes of crude oil flowed from the ship, contaminated the coast and left thousands of fish and birds dead in the area. The effects of the crash are still felt.
Animals and their environment experts are concerned about rising marine pollution. Green turtles and turtle fishes are sometimes found dead along the coast, with their species being endangered.
Their deaths are due to pollution, especially by throwing plastic waste into the sea, falling into the sea of industrial waste. Many species of fish have now become rare in the Arabian Sea.
