The increase of tanneries in Pakistan is causing severe environmental degradation as the untreated effluent used in the tanning process is released into nearby water reservoirs and the sea. In addition, air pollution is on the rise with the tanneries burning residuals (i.e. hair) from the tanning process into the atmosphere.
The leather industry of Pakistan is continuously growing in contrast to other industries but with a huge price. The price is in the shape of extreme high risk to human health and infertility of lands where this poisonous waste is being dumped unfiltered. The official stats regarding human health will never accurately reflect the gravity of the situation. Some are attributing this situation no less than discharging radioactive material in the open air. A number of so called environmental protection agencies and NGOs are “trying to tackle” this issue but seems like that the leather mafia in Pakistan is way more powerful than them!

I agree in toto with the observations of the writer. But at the same time we must appreciate that Pakistan is still in the initial stages of industrialisation. General awareness about threat to environment is increasing, I am sure gradually things will improve.
Thx for spending some time to describe the terminlogy to the learners!
Very good
