Pakistan, a country that is known to host many aquatic species is facing an alarming situation regarding their natural habitat. The seaside environment in Pakistan has been mainly corrupted throughout the most recent 50 years because of freshwater redirection for agribusiness, modern and metropolitan water contamination. These appalling causes are to a great extent driven by public policies that have supported agribusiness and industry over the coastal region which leaped the country trades.
Mangroves spread more than 600,000 hectares are covered by 17 significant and multitudinous minor streams. They are the biggest dry environment mangroves on the planet, which are situated in Pakistan. They serve as a birth site for hatchlings of fish and many other marine creatures.
There has been an extensive subjective and quantitative loss of mangrove forests in Pakistan throughout the last 50 years. The significant reduction has been subjected towards the freshwater supply as well as an increase in water contamination across the Indus Delta. Particularly there is a consequential rise in overharvesting of mangroves by the local community resulting in the disappearance of the mangrove ecosystem.
Overharvesting of fish assets arose as a vital factor for biodiversity misfortune in the mangrove environments. Over-fishing brings about the eradication of certain fish species, causing changes in the biodiversity of mangrove forests where nearby fish species spend a piece of their life cycle.
The contamination in the Arabian Sea is on increase because of maritime and different variables, causing a decline in the fish population, crumbling of navigational establishments, and actual harm to boats and ships. Although 100% check and balance are not possible yet some up-gradation could be a possible solution.
Karachi harbor region, including the marine channel, is quite possibly the most oil-contaminated zone along the bank of Pakistan. The complete zone of Karachi Port, including backwaters, is around 25 sq. /km. Around 3,000 to 4,000 boats visit the port every year. In course of routine activity, ships release oil blast water and bilge water and load tank washings. Adding worry to the already overwhelmed situation is the multiple organization providing oil storage and terminals which are the key factors of damaging the marine environment.
Radioactive pollution is another factor supporting the appalling situation towards the seaside of Pakistan. As materials contaminated are used by concerned authorities for multiple purposes for intense defense, nuclear power, and research purpose, they also act as the key factor in defacing the oceangoing, resulting in tearing down natural habitats of marine species.
Around 8,000 metric tons of trash are created every day in Karachi, a lot of which is unloaded arbitrarily at different areas because of the absence of a proper garbage removal facility. A portion of this trash discovers its way into the ocean. Aside from that the city produces roughly 280 million gallons each day of homegrown and mechanical waste. Almost 80% of untreated metropolitan and mechanical waste from 6000 modern units of Karachi releases into the ocean.
The public authority offices liable for upholding NEQS are understaffed and under-prepared. The overall population and the industrialists, then again, show no craving to share the duty regarding improving or securing the climate. The ineffectiveness of EPAs in controlling marine contamination will keep on adding to ecological corruption.
EPA is the U.S. government’s specialized point of convergence for the usage of the LBS Protocol, which focuses on two central questions: domestic sewage (wastewater) and agriculture non-point source contamination.
EPA is attempting to lessen marine degradation in various manners. The EPA Sindh has proposed the advancement of a far-reaching project of activity to handle marine contamination issues on long-haul premises. EPA is working with government office accomplices, outside countries, industry, and non-governmental associations to guarantee that worldwide choices and the board of marine contamination issues uphold EPA’s central goal. The urgency behind the idea and effort is to ensure the wellbeing of humans and also to defend the common habitat which covers the air, water, and land whereupon life depends.
Gawadar is the golden sparrow and the economic activities are a lifeline for the tumbling economy of Pakistan. But the underwater ecosystem of Gawadar will also be destroyed if the province and center don’t act on time. Baluchistan and particularly Gawadar will become the next Karachi in terms of a horrible sea belt.
The situation nowadays at Pakistan Coastal line and Indus delta is horrifying also worrying regarding multiple factors which can turn out to be a devastating case. Some study cases have painted an appalling picture, which cannot be ignored. Serious actions should be taken to avoid any further damage to the region’s marine environment.
