The overall global environment is declining fast and for Bangladesh it has been doing so more rapidly during the last few decades because of many obvious reasons. But we are still not surprised. We, all of us, pollute our own cities with trashes. So how can we claim owners of these factories, with hardly any education be conscious about the environment, feel the need to protect the environment? We need to count ourselves first to protect our own ecosystem to survive in an earth which will be a gift for our next generation – ONLY IF WE CARE
“Pollution is an immense crisis that is slowly destroying the world that we live in. It is crucial for every individual to do what he or she can to clean up the environment. Whether it is in the home or on a management level, or within us, every person is important and has the ability to make a difference and can help to stop pollution”

The mighty river Buriganga is now so polluted that all fish have died, and increasing filth and human waste have turned it like a black gel. Even rowing across the river is now difficult for it smells so badly.
Bangladesh has about 230 small and large rivers, and a large chunk of the country’s 140 million people depend on them for a living and for transportation. But experts say many of them are drying up or are choked because of pollution and encroachment. A World Bank study said four major rivers near Dhaka — the Buriganga, Shitalakhya, Turag and Balu — receive 1.5 million cubic metres of waste water every day from 7,000 industrial units in surrounding areas and another 0.5 million cubic meters from other sources. There is no fish or aquatic life in this river apart from zero oxygen survival kind of organisms. Bangladesh enacted a law in 1995 making it compulsory for all industrial units to use effluent treatment plants in a bid to save river waters from pollution, but industry owners often flout the rule.
Dhaka city alone generates about 3500 to 4000 m tons of solid wastes per day. The amount increases with the increase of population every year. The domestic, commercial, street sweeping, combustible and non-combustible wastes include discarded food, grass, plants, paper, cardboard, textiles, plastics, polythene materials, glass, metals, and construction debris.
Industries and factories have been polluting the water bodies in and around Dhaka city for the longest time. There are about 1000 small and large industries in Dhaka city producing a large amount of toxic and hazardous wastes contributing significantly to environmental degradation. The emission of various greenhouse gases such as CO2, CH4, among others from various industries, increases the overall temperature of the earth, resulting in global warming and making the area unsuitable for human habitation, animals and plant species.In the Hazaribag area of Dhaka there are 149 tannery units daily producing about 18,000 litres of liquid wastes and 115 m tons of solid wastes; nearly all of these are dumped in the Buriganga river, and a part is thrown into nearby drains and sewers. These wastes contain sulphuric acid, chromium, ammonium chloride, ammonium sulphate, calcium oxides etc. These may seep into the ground causing ground water pollution. Also, the intense, unpleasant odour affects the health of the people of the surrounding area. tannery wastes have a very serious and negative effect on the ecosystem.
‘It is very easy for every single person to help stop pollution and stop destructing the earth. It can take little effort, but can be something that makes a huge difference. Start by evaluating how you can make small changes. Even the smallest changes in your own life can have a massive impact.’
