Plastic microparticles threaten unique Galapagos fauna
Tahjeeb Hossain Chowdhury: The Scenic Oceanside beaches and marinas are now heaped in washed up or thrown out plastic from commuters on the beach. The Galapagos seems like an industrial wasteland filled with plastic, metal, and a host of trash strewn across the shores. This is indicative of how callous the overall process of waste management in the area has been. Yet, underneath that, there is a threat to the inhabitants of the area be it human and fauna. The microparticles from the waste, especially ones from the plastic pose significant damages.
The microparticles from plastic washing up on the shores have come from nearby countries. The archipelago in the pacific is 600 miles west of Ecuador. The waste from nearby countries or in some degree continents washes up on the shores. The microparticle discharge from these plastic wastes can find their way into the stomachs of unsuspecting fauna like the Iguana, tortoise, birds. These can become fatal and cause deaths of the natural inhabitants. Researchers from the Galapagos National Park have said that the particles might end up in the food of the humans as well. With a population of 25000, that risk might be dire than the words spell them out to be.
Galapagos is also a heritage site according to Unesco and more efforts from the authorities of surrounding South American countries are expected as the majority of the waste pertains to these countries. Park Rangers and volunteers with their gloves and sacks are the only defense against the rampant waste that faces the Galapagos islands. Most of the plastic washing up has been Chinese Products ranging from plastic shampoo bottles to food containers to even unknown objects that look like adult toys.
The locals and the volunteers have made an appeal to the surrounding authorities. In recent years of 2018 and 2019, the waste has accumulated to over 6.5 tons with no signs of the number dropping anytime soon. Authorities and International bodies have to come together and address the situation. Rare species of fauna including the marine Iguana depend on the food in algae, insects, and small crabs. The particles mixed in the ocean endanger their existence at a fatal level. Soon, all species including humans in the Galapagos may be at danger if no steps are taken.

Polythene Use Still Rampant
Tahjeeb Hossain Chowdhury: The Polythene Use in Bangladesh is still rampant and excessive as ever. The point of the damages that polythene causes to the environment have been stressed more than ever, yet the mass populace has had a hard time discarding the usage of such materials. The worrying problem in this is the visible rejection of the environment-friendly alternatives made of Jute.
The use of Polythene has been linked to water clogging, water pollution, fertility reduction, and more debilitating damages to the environment. There have been lots of activities to drop polythene as a regular usable alternative and more stress has been put on ‘Sonali Bag‘ made from Bio-Degradable components from Jute. Bangladesh historically has taken a stern stance on reducing the usage of Polythene as it was the first country to outright ban the use of Polythene in 2002. But the action never went beyond documentation as the authorities failed to properly implement the ban.
The Sonali Bag alternative is not only beneficial to the environment but also had a great demand. But there has been a severe lack of financing on the project. Dr. Mubarak Hossain Khan, a leading scientist into the Sonali Bag project, has received interest from individuals and corporations alike. The Bangladesh Jute Mill Corporation or BJMC has been in contact with willing business associates who want to use the alternative bags. Polythene Bag Supplier Abdur Razzak being one of them. The technology and Raw Materials are plentiful in Bangladesh but the funding is not enough. There is a need for BDT 300 Crore in order to make the 20 ton Sonali Bags in order to meet the countrywide demand. Dr. Mubarak has said that there have been no steps from the Government to fund the production.
Thus, Polythene use has remained mostly the same. Anti-polythene activities have also decreased drastically. A total of 44% drop from previous years. The fine collection has dropped from BDT 1.17 Crores to BDT43.71 Lakhs in recent years. The seizure of illegal Polythenes has gone down from 152.74 tons to 104.6 tons as well.
The cheap production cost, as well as political shelter towards the producers, can be some of the main reasons behind the usage of polythenes despite the visible demerits.

Demerits of the Generator on the Environment
Tahjeeb Hossain Chowdhury: In many areas of Bangladesh, there are lots of localities that still suffer from power outages and load sheddings. To counter that, Generators are used to make sure that the power stays uninterrupted throughout the power outage period. But the generator usage has a lot of perils that threaten the normal living quality of the citizens.
Many areas like Mirpur, Farmgate, Jatrabari, Kamrangirchor and some areas where industrial production is prevalent; have been suffering from the effects of the generator smoke. The populace surrounding factory areas have complained about the black smoke that comes out of the chimneys and exhausts.
The Generator usage creates residual particulate matter that gets mixed with the environment. Researchers in a recent study by the Center For Science and Development, based in Delhi, provided levels of PM2.5 and PM10 rises 10% to 30% in such areas where the diesel generators are in use. According to Environmentalist Dr. Lelin Chowdhury, the particulates can cause serious illnesses in people that can even lead to death.
Dhaka has been ranked second in the World Health Organization air pollution index. In daily pollution indexes, Delhi and Dhaka had been trading places in first and second places in recent times. Bangladesh is also the seventh most vulnerable country to be affected by climate change.
Every year more or less 15000 people have been affected by air pollution due to air pollution. The top 10 diseases that affect people most and lead to deaths have 5 respiratory-related illnesses which all have an origin in air pollution. The five diseases are lung cancer, ischemic heart disease, lower respiratory tract infections, stroke, and chronic obstructive pulmonary disease. Children suffer from asthma-related problems more often than not.
The Poribesh Bachao Andolon initiative has time and again pressed on the importance of getting rid of the sources of air pollution. Its Chairman Abu Naser Khan has opined that any fossil fuel has the potential to cause air pollution. “Getting to the bottom of the usage of such fuels and decreasing uses should be a top priority” adds Abu Naser.
The Urban Areas in Bangladesh are being consistently polluted by generator smoke and decreasing their use is a must for us to ensure better living standards and save lives.

Bangabandhu Nodi Padak
Tahjeeb Hossain Chowdhury: The introduction of the ‘Bangabandhu Nodi Padak’ has been undertaken. As a part of the efforts of restoring rivers and safeguarding the future of the riverine environment, the award will be given to people and organizations that come forward to take steps to save the rivers in our country.
The rivers that have governed our way of life for centuries have been under threat because of rising pollution. Many rivers in our country have dried up. If rivers do not function in the proper way, a huge dent is expected in our agriculture and our economy. So the government has been playing an active role in saving rivers and the environment that depends so much on the rivers.
A total of four awards is planned. One in the district levels, while the other three at the national level. The district-level award will consist of a certificate, a gold medal, and a cash prize of BDT 30000. At the national level, the difference would be in the prize money with BDT 50000 as a part of those awards.
The awarding committee will be on Upazilla, district, and National levels. Each will have its own awarding committee who will judge the efforts of river protection. The award is being conducted and drafted by the Shipping ministry. The tentative date for the award is likely to be in September. This is because the ministry wants the award ceremony to coincide with the ‘World Rivers Day’. It might also be awarded on any date of the Prime Minister’s availability. Dates, number of awards, the prizes, and other facets are subject to change as per the Shipping ministry.
The rivers in our country have played a vital role in our way of life. Yet, they are subject to pollution, illegal establishments on the banks, and have seen a lack of effort in saving the rivers in general. The shipping ministry wants to encourage and make sure that saving rivers is a priority on an individual as well as personal levels. The ‘Bangabandhu Nodi Padak’ will be a sign of incentive and promotion of the notion to award acts of riverine restorations.

“Corona” – Worldwide context and our lives
Zaman Tuhin Zohn: Honestly, what to do in times of global epidemics and pandemics? None of us have the answer to this question. Because there are probably no other people in the world who have witnessed such an epidemic before. Even in this age of technology, the “Covid-19” has shown us how far behind we are in terms of health care.
Whether the “Covid-19” came naturally or was created in a laboratory, we kept it separate on social media or world leaders. We just look at how helpless mankind is today.
How much the powerful countries are lost with medical supplies! In that context, I personally have never believed that our country, our policy makers and the general public will not be lost.
In fact, in our country, “Dengue” epidemics often take shape. Just blame the mismanagement? Or incompetence? Or is it wrong to make a decision? As an ordinary citizen I can either blame everything, or accept everything. The funny thing is, I’m not doing either. For more than a month now, almost all the people in the country have been panicking about “Covid-19” or some of them don’t know anything about its danger.
The lives of the garment workers were almost ridiculed. When the Ministry of Public Administration announced a general holiday on 25 March 20. People got leave and went for a walk. After the trip, public transport was stopped. But on 4th April 2020, the garment owners did not understand what to do or say? Believe me, even in a small organization, it is not possible to prepare in this short time to follow adequate hygiene. Probably a factor as to why they’re doing so poorly. After that there was nothing left to say, they went back and the matter spread.
Some remained, so the factory was open. Someone was making a nominal mask, PPE. Someone finished the handiwork. “Covid-19” but kept spreading. People took to the streets hungry. The government only announced incentive packages for the garment industry. From April 5’2020, many factories announced lay-offs. Even in the way that is clearly stated in the law, again no one is following the law properly. Because, I said, not everyone has the experience of such a situation. On top of that the owners of this large industry hire people just to pass the audit, the owners know very well how much or space they get with adequate knowledge and practice of law.
Anyway, this time the fog is still going on. Until the latest news, there will be no lay-off. After the meeting with the bonus. But the punch is elsewhere. The workers who have worked and those who have not worked out how and how rationally the percentage of their wages has been fixed does not match mine as ordinary people. Outside of these workers, this pandemic is only for government incentive packages. Those who give up their lives and work tirelessly, submit papers to scheduled banks, have their salaries, jobs, or life guarantees all there is to it from the trade unions, BGMA, or the Ministry of Labor. Not in anyone’s eyes.
They are not owners, they are not workers, what they are, they are not found in any definition of the constitution. The names of their titles are not found in any schedule. But I used to get pictures, every day some people would just stand in front of thousands of people to collect signed papers. I named them “Educated slaves”. Those who can’t move down the street, can’t ask anyone. If the owner says 50% salary for now, they can’t even protest. But they are still going to different places with relief at the behest of the owner. Maybe this is the reason why many people are forced to be dishonest with the organization with a clear conscience.

14 Thousands Square kilometer Area will Disappear
Ashik Rahman: 14 thousand square kilometers of the Indian subcontinent will disappear for one meter of sea level increases. And six meters increases will absorb the coastal area of 60 thousand square kilometers for global warming matter.
Increasing global warming greenhouse effect’s, Sea levels if the water level rises by one meter. The Indian subcontinent coastal area about 14 km from the sea fishes are very vulnerable. A group of scientists in the study was asked to report on. The way they have been attributed to climate change.
Sea level will rise because of sea temperatures increase, glaciers, and ice neck and ice memoranda down. Numerous reports warned that one-meter water level increases of 48 ecoregions that crash is 18 which is Krishna, godabari badabanera quarter. Destroying UNESCO World Heritage area, Sundarbans and Gujarat saltwater of the shore half. The level of the six-meter does lead to the drowning that is at risk of 7 ecoregions.

The sea level of one meter increases the damage of the species could not appear. But drowning is seven protected areas including Orisara inside the cell, Silika Lake, Point kayalimeyara Island, Interview Island, lothiyana Island, and the sajanekhali. This disaster will be lost in the hundreds of rare species those are living in down the coast ecosystem operation. The Bay of Bengal and the Arabian Sea coast have been saved and the unsaved biodiversity of the area in endanger.
Sea level rises if the country’s risk the most, the top has a geographically from the low lying terrain Bangladesh. Most vulnerable in the face of the cit, Global banks, according to water level 14 centimeters increases for two people endanger those who live in the 700 kilometers long low lying coastal areas. Climate change impacts will be 47 million dollars to prevent the government of Bangladesh. It has two major projects, which is a coastal area and builds a thicker lawn.
The main cause of global warming, fossil fuels produce carbon-die-oxide and greenhouse gas. Greenhouse gas increases the temperature of the earth’s surface which is a major global warming threat.

Dhaka Water War
Fahmida Sattar: Dhaka water war, it is often said that mankind will experience a war over water in the near future. The claim has some truth in it, no doubt about that. But the term ‘Dhaka Water War’ is already an existing truth for Dhaka dwellers. It is indeed irony for a city surrounded by a river that it can not provide the least quantity of water. Experts often blame mismanagement and unplanned urbanization, rapid population growth in cities, etc. This article ‘Dhaka Water War’ will attempt to investigate the water crisis of Dhaka from a perspective where water is considered as a birth right not a mere commodity. In light of this idea, the article will also make an effort to provide some suggestions to lessen and then solve the water crisis, which has made the city of 15 million people a ‘living hell’. The focus will be on the community measures which require less budget and bureaucratic complexities.
The Current Situation
According to a report by The World Bank, Dhaka has the highest population growth rate for a city in the entire world. Around 3-4 million people, which constitute about one-fifth of the total population of this mega-city, live in slums. Most of the slums lack any proper water supply lines from WASA. Slum-dwellers standing in long rows, waiting for hours to collect a single gallon of water, is a very common scene.
Dhaka Water Supply and Sewerage Authority (WASA) said they are producing 160 to 165 crore liters of water which is about 25 percent less than demand. It extracts groundwater using 620 deep tube wells. In addition, more than 2,200 private wells also draw water to serve high-rise buildings and various institutions. The underground water now provides 88% percent of total demand, which was 95% before The Saidabad Water Treatment Plant went into action in 1995. As a result, the subterranean water level drops about 3 meters every year. The rate is 53.75 meters in Mirpur, 18.59 in Mohammedpur and 8.22 meters in Sutrapur. This rapid fall of underground water level does not only create a crisis in the supply of water but also the vacuum left by this fall possesses a great threat of an earthquake. Besides saline water is intruding to fill up space, posing a threat to getting fresh drinking water in the future.
As Bangladesh is often titled as `land of rivers’, the nearby rivers could be considered as a source of water to diminish the pressure on underground water. But WASA emits 1,000 tonnes of untreated human waste into the rivers adjacent to the city every day, which means river water is unfit for human consumption. The unmonitored industrial wastage system is worsening this problem day by day.
Community Measures of Dhaka Water War
One of the key factors which have a major effect on the gradual descending of subterranean water level is that our city planners often leave little chance for the rain water to get into the ground. Because most of the city areas are paved over, rainwater cannot be absorbed by the ground. Instead, it runs across the pavement, picking up oil, street debris, animal feces, and other waste as it moves. Reducing the amount of runoff rainwater is very critical to ensure the satisfactory level of underground water.
Experts use the term ‘rainwater harvesting’ to discuss the process of accumulation and deposition of rainwater for reuse on-site or underground. It goes without saying that the best way of letting rainwater go into the ground is keeping the importance of permeable surface in the head. For areas where hard surfaces are necessary, pavements should be built in a way so that it let the rainwater reach a permeable surface.
Building rain barrels is another effective way of reducing runoff and conserving rainwater. According to the tutorial, provided for the people of Minnesota, the USA by the state government, it needs only about half an hour to make a rain barrel at home. As Bangladesh yet to reach extreme water crisis conditions, building a community rain barrel is enough to tackle the present situation.
Rain gardens are another community mean of rainwater harvesting. These are concave-shaped gardens that collect runoff from downspouts, driveways and other hard surfaces. Plants that tolerate “wet feet” should be planted in the bottom, while plants that need less water are planted on the edges.
Rainwater harvesting has proven to be successful in other parts of the world. The 35 rain water harvesting systems working in NYC’s community gardens collect 422,900 gallons of water every year. That’s enough for 264,313 toilet flushes! The Institute of Water Management (IWM) shows if 60 percent of total rain water can be harvested in a city like Dhaka, it will be capable of providing 200 million liters of water every single day.
In India, the state of Tamil Nadu was the first to make the conservation of rain water compulsory for every building to avoid the rapid decrease in the underground water level. As a result of this, Chennai, the capital of Tamil Nadu, saw a 50% rise in water level in five years. The other states gradually followed Tamil Nadu’s example and found surprising results. The state of Rajasthan receives a scant 400 mm of rainfall annually where the relatively dry western region of Rajshahi, receives 1600 mm of annual rainfall. The decade of the 1980s is Rajasthan is marked with the revival of the ancient tradition of creating Johads, large rain water reserve tanks. Now there are over 4,500 working Johads, lessening the water crisis of one of the driest places in this subcontinent.
Conclusion
In comparison with the vulnerable economy of our country, one can easily draw the conclusion that no quick solution in near at hand. First of all, the crisis should not be let to go out of control. This can easily be done by reducing the quantity of usage and wastage. Moreover, community measures are easy to be introduced and apparatuses are very available. As there is a wise saying, “All’s well that ends well”, the article is being concluded with good news. This November, Honorable LGRD minister has announced that the government is going to provide water supply lines in every slum area of the city within December 2015. One can raise doubt about whether it is really going to happen at last. But what can satisfy Dhaka dwellers is that this matter is taken to attention. The whole world today is talking about the impending severe water crisis. Bangladesh should not be left behind.

Dhaka Residents Flinch as Air Quality Worsens
Tahjeeb Hossain Chowdhury: It is no secret that Dhaka is a city that has been plagued with air pollution for a long time. The quality of air has worsened in the industrialization of the 1980s, 1990s, and of course the 2000s. Bangladesh has been leading the charts when it comes to pollution and that is definitely not something to gloat about and should elicit an opposite reaction.
In recent times the air quality issues have plagued the whole world and Bangladesh is certainly not an exception to that. Bangladesh has been put in the rankings as one of the worst countries to live in, in terms of air quality. Dhaka has been named one of the most inhospitable cities in the world.
Dhaka is the 17th worst city in the world in terms of air quality in the world. Delhi and Dhaka have been trading places with each other as the most polluted cities in the world on a daily basis. What’s alarming is the amount of smog and dust particles in the air in Dhaka. With the top 10 causes of death in Dhaka having 5 respiratory and heart conditions or a source of such, this is technically an alarming situation.
Dhaka has an infrastructure that resembles a board of dominos with buildings and structures piled with little or no space in between. With living spaces and industrial sites being lumped together, the pollutants rapidly mix with the air and eventually in the lungs of citizens.
With brick kilns, factories, construction sites, metal workshops, and transportation fumes so much intricately mixed with our city living quarters, air pollution is bound to be an issue. With the worldwide situation getting so bad, there needs to be precautions and studies in place to mitigate the situation. Citizens in Dhaka have been subject to a varying range of problems pertaining to such harsh air quality.
Underlying conditions such as lung cancer, various forms of heart disease, and strokes are becoming common for the citizens. So proper steps from the government and citizens alike is sorely wanted to tackle this ever-present calamity. Regulations and restrictions, as well as the promotion of good environmental habits, should be the key to tackling these problems.

Aqua Stressed in Mega City, A Road to Prevent
Joni Alam: Water is essential to health, agriculture, energy, science, industry, transportation, and recreation- In short, to human existence- water is an incredibly complex matter, at once political, economic, legal, social and ecological in its nature. For any region, water fixed its national plan, domestic and external policies of the region’s principal actors. As water shortages occur and full utilization is reached these policies tend to be framed more and more in zero-sum terms, adding to the probability of discord. The foremost water supply of a country is used for its city men although the water supply and resources of a city are limited.
Bangladesh is home to 2.15% of the world’s population, and merely .24% of water resources. The country is almost entirely dependent on cross-boundary water flows for its supply.
Dhaka, the capital city of Bangladesh, faces severe water shortages. While the city needs 2.2 billion liters of water a day, it can only produce 1.9 million, said, Dhaka’s Water Supply and Sewerage Authority. Shortages are so severe that some areas of Dhaka will have no water for several days. Sometimes, the dwellers of this city do not get a single drop for the months, which makes lives miserable and they have to survive for months by buying water from WASA tankers, paying sometimes more than twice the official price which is not hygiene. As a consequence, most people have to suffer from diarrhea.
The city dwellers sometimes stop fetching water from the pump and use the supply water instead. This source of water is not properly managed, which will put the city at risk of severe water shortage in the future. When there is a supply of water from WASA, it is too dirty and unfit for consumption. Even despite boiling it for more than an hour, the bad smell doesn’t go. Water experts have called for the city to increase the usage of surface water sources such as ponds, rivers, and canals.
But surface water is being polluted across the Dhaka due to indiscriminate discharge of industrial wastes into the rivers so that Dhaka is going to face an acute problem in getting pure drinking water. It is the most acute fear for the middle class and poor people in this city as well.
We have seen most of the times, poor people like women, stand up with their empty jar in the open place for getting water and it happens sometimes by the children bring out a silent procession with a pitcher in the capital demanding smooth water supply. None of them are concern about the purity of the water. They only know, they have to survive their lives through that water. The city dwellers are dependent on readymade water rather than natural water instead of having a huge source of natural water because this water is being polluted and used improper ways. It is happening, of course, for the lack of taking adequate steps of proper authority.
It should be acknowledged that one of the causes of the water crisis is, of course, the continuously growing population of the city. Development of utility services has to assume a stable population, if population swells continuously, infrastructural facilities will be bitterly challenged to match up. The daily requirement of water in the city is 200 crore liters whereas WASA can supply at best 180 crore liters. As WASW’s main source is groundwater, the groundwater table keeps falling with an obvious risk to the environment.
In Bangladesh, Dhaka (capital) is the densest city with 12.8 million populations according to the official estimation but an unofficial estimate put this figure closer to 15 million, including 3.4 million living in slums. Another 300,000 to 400,000 people migrate to the city each year, which has witnessed a four-fold increase in its population in the last 25 years. According to the World Bank, the mega-city has the highest population growth in the world.
The city requires 2.2 billion liters a day, but can only produce 1.9 to 2 billion water while almost water comes out from ground resource. Specialist warns authority’s for its over-dependency on groundwater and suggest to usage the surface water. Dhaka City is located on the flat delta of three major international rivers; the city is surrounded by a network of rivers; the Buriganga to the south-west, the Turag to the north-west the Balu to the north-east and the Shitalakhya to the south. and it has been seriously damaged by the flood of river overflow and heavy rainfall in the rainy season. Dhaka receives about 2,000 mm of rainfall annually, of which almost 80% falls during the monsoon. Floods are one of the main natural hazards affecting the city and are associated with river water overflow and rainwater stagnation.
The city has become more vulnerable to intense urban flooding due to heavy and unpredictable rainfall in recent years. The drainage capacity of the city has also decreased alarmingly due to the development of unauthorized settlements. Illegal occupation of drainage canals and wetlands by land grabbers has further contributed to the problem. In the rainy season, the city mostly collapsed its water supply and drainage system due to it unplanned and unreliable construction, overloading, shortage of workforce of DWASA, lack of management and delaying in repairing of failed part and In the dry season from March to May water crisis looming for power shortage and outages. Many people didn’t get water for days because DWASA is unable to extract enough water to meet demand. And many people complained that water the rendered is undrinkable.
WASA runs 600 deep tube wells in the city to extract water, and there are also 2,000 private tube wells throughout the city. About 87 percent of Dhaka residents use groundwater, mostly from deep tube wells, while the rest use treated surface water. (IRINA 18 November 2014). Adding to the water crisis, dwellers of some areas were getting unusable foul-smelling water from Water Supply and Sewerage Authority. The stinky water was allegedly spreading waterborne diseases as well.
This water crisis creates a panic situation in the world’s largest megacity. Over 7,000 children die from diarrhea every year in Bangladesh and water-related diseases cause nearly a quarter of all deaths. (Water aid annual report 2013-14)
Water-related improvements are crucial to meet the Millennium Development Goals, reduce child mortality, and improve health and nutritional status in a sustainable way. In addition, they induce multiple social and economic benefits, adding importantly to enhanced well-being. It’s very important to create well planning and good management to reduce the water crisis. It’s needed to trace a forecasting project line about total water demand and area-based demand of Dhaka city by estimating projected population growth and projected economic development and also forecasting water supply by estimating Rainfall projection, surface water projection, and groundwater projection. Bangladesh’s government not yet pegged water police while many developing countries like Sri Lanka, Indonesia, Malaysia are cajoling the advantage of national water police. Ironically Bangladesh is a lower land country and we call our country mother of the river but we are immersed in a water crisis, not a shortage of water but improper regulation and pie situation in water authority.
The drainage system of Dhaka city is heavily dependent on the water level of peripheral river systems. During most of the monsoon period, the water level of the river remains higher than the water level inside the city area. Hence, the draining of water by gravity flow is not always possible.
Stronger action is needed now. Government steps in addressing this problem to date have been inadequate. Water problems stem mostly from an over-dependence on groundwater and the World Bank notes that the city obtains most of its water from over-exploited aquifers. Initiatives to cut the dependency and increase the use of surface water should have been taken much earlier. We have to use surface water to take by purifying and in this regard industrial attitude must be changed to pollute water.
In this connection, it can be attached importance to creating mass awareness of the matter. The government has to ensure setting up of Effluent Treatment Plants (ETPs) at all industrial units for proper waste management to avoid water pollution. As we know, most of the industries have no ETP facilities for waste management, so the government has to make it mandatory to set up ETP facilities at all industrial units to save the surface water from pollution. In this regard, the JU Environmental Science Department has already installed a wastewater treatment laboratory under the Higher Education Quality Enhancement Project (HEQEP) on the campus for purifying the industrial wastewater. The lab will provide a proper direction to the industrialists to operate its treatment in a sustainable way. We must ensure effluent treatment plants to be used by all industries. Also, the Water and Sewerage Authorities must ensure the use of human waste treatment plants.
Safe water is essential for our existence and is related to safe food which means with the rising absence of safe water, the food produced at homes and also in eating places will be unsafe and lead to stomach and gastrointestinal diseases. Those industries which do not use effluent treatment plants in the near future must be stopped until they start using effluent treatment plants. Our universities like BUET and JU must come up with the latest models of effluent treatment plants that would serve our requirements for safe water. Also, all canals and rivers and water bodies must be surveyed to see the extent of water pollution and treatment plants must be set up accordingly.
Other devices such as the Lifesaver bottle’ incorporate an extremely fine filter technology to filter out all bacteria and viruses. This makes the water drinkable from any source. The filter is useable for 15,000 liters of water. Once the filter is easily replaced and then the bottle is usable for another 15,000 liters. It can make water drinkable from any source, stops the spread of water-borne diseases, saves lives and can easily be served to the city dwellers. Products like the reverse Osmosis Sanitation system’ (ROSS) use movement generated by wheels to pass filters through a tank of water that cleans it of bacteria and viruses. It can carry 50 liters of water in one tank and stops the person from having to carry the volume of water as they can simply roll it. It also acts as a storage device for large quantities of water. It can completely clean the water of diseases or bacteria, prevents the spread of water-borne diseases, acts as a storage device. Governments and aid organizations can also invest in providing safe and clean water in the city areas in the form of taps or standpipes. The water for these taps could be sourced from boreholes that use unpolluted groundwater as their sources. It will reduce the number of deaths from drinking polluted water by providing a reliable clean source.
Overall, we should conscious to waste the water. Our government should take a hard step to control this situation in this city for the betterment of city dwellers.

Shibsha River Erosion threatens for Sundarbans
Tahjeeb Hossain Chowdhury: The Shibsha River is threatening to consume the various vegetation found in the West Sundarbans. The World’s Largest Mangrove Forest, the western part, in particular, is facing a situation where even the Iconic and Namesake of the forest, The Sundari tree is also under immense threat.
The bank of Shibsha River has faced a damning case of erosion in recent times. The state is so dire that the erosion is threatening a land that expands to 15-20 kilometers in length. The Catastrophic erosion is causing the world-famous flora of the Western side of Sundarbans in a significant way.
Correspondents of different media have reported and published on newspaper that the erosion originally started from the eastern bank of the River. Inhabitants and fishermen of the area have lamented that erosion has intensified a lot during recent times and has made life quite difficult for humans and nature alike. They have also opined that the forest department should shoulder the blame for the spread as they played no significant part in stopping the whole spread to the western shores.
Many big trees and vegetation in the area were washed away and consumed deep beneath the riverbed. Two landmasses that develop because of silt, also known as Chars have appeared in the area. Professor Abdullah Harun Chowdhury of the Khulna University has opined that the salt portion in water and soil in the Noilan, Khulna, and Satkhira has risen and continues to rise.
He also added that the Salt and soil level increasing has lead to the soil losing the bond. Thus, as a result, has led to this terrible degree of soil erosion in the area. The forest officer in the region, Md Basir Al Mamun, said to the media that they have not yet been able to do a survey of the damage caused by the ongoing erosion. The last survey from the 2201-2014 period shows a 1 percent increase in the forest.
The forest conservator in the Khulna Area, Md Moinuddin Khan has said to media that the erosion is a natural occurrence in the Mangrove area. He has also said that they are ready to take necessary measures to stop the erosion.
