Dhaka, the overcrowded capital city of Bangladesh, has ranked 11th on the list of cities with the worst air quality with an AQI score of 103 at 10:30am this morning (June 21, 2025). Today Dhaka’s air was classified as ‘Unhealthy for sensitive groups,’ according to the AQI index. Such air quality continued for the past few days.  When the AQI value for particle pollution is between 50 and 100, air quality is considered ‘moderate’, usually sensitive individuals should consider limiting prolonged outdoor exertion, between 101 and 150, air quality is considered ‘unhealthy for sensitive groups’, between 150 and 200 is ‘unhealthy’, between 201 and 300 is said to be 'very unhealthy', while a reading of 301+ is considered 'hazardous', posing serious health risks to residents. Uganda’s Kampala, Democratic Republic of the Congo’s Kinshasa and Indonesia’s Batam cities respectively occupied the first, second and third spots on the list, with AQI scores of 155, 147 and 139 respectively. Dhaka’s air quality continues to be ‘moderate’ The AQI, an index for reporting daily air quality, informs people how clean or polluted the air of a certain city is and what associated health effects might be a concern for them. The AQI in Bangladesh is based on five pollutants: particulate matter (PM10 and PM2.5), NO2, CO, SO2, and ozone. Dhaka has long been grappling with air pollution issues. Its air quality usually turns unhealthy in winter and improves during the monsoon. As per World Health Organization (WHO), air pollution kills an estimated seven million people worldwide every year, mainly due to increased mortality from stroke, heart disease, chronic obstructive pulmonary disease, lung cancer, and acute respiratory infections.    

Dhaka, the densely populated capital of Bangladesh, recorded a moderate Air Quality Index (AQI) score of 64 at 10:54am on Thursday, ranking 48th among cities with the worst air quality—better than Dubai (score of 128, ranking 8th). Today Dhaka’s air was classified as ‘moderate,’ referring to a light health threat, according to the AQI index. Such air quality continued for a fourth consecutive day on Thursday.

he European Union (EU) on Thursday reaffirms its unwavering commitment to protecting nature, promoting biodiversity and safeguarding the environment.  The EU Embassy in Bangladesh made the remarks in a brief message marking the World Environment Day. Led by the United Nations Environment Programme (UNEP) and held annually on 5 June since 1973, World Environment Day is the largest global platform for environmental public outreach and is celebrated by millions of people across the world.  In 2025, it is hosted by the Republic of Korea. Time is running out, and nature is in emergency mode.  To keep global warming below 1.5°C this century, we must halve annual greenhouse gas emissions by 2030.  Without action, exposure to air pollution beyond safe guidelines will increase by 50 per cent within the decade and plastic waste flowing into aquatic ecosystems will nearly triple by 2040, according to the UN. Globally, an estimated 11 million tonnes of plastic waste leak into aquatic ecosystems each year. More than 800 marine and coastal species are affected by this pollution through ingestion, entanglement, and other dangers. Microplastics in the seas now outnumber stars in our galaxy. The annual social and environmental cost of plastic pollution ranges between US$300 billion and US$600 billion.

The World Environment Day is being observed around the world on Thursday with a call to raise global awareness about the damaging effects of plastic waste on ecosystems, wildlife and human health. In Bangladesh, the day’s programmes will formally be observed on June 25 due to Eid-ul-Azha holiday.   The theme of this year's day is “Beat Plastic Pollution.”  The campaign seeks to raise global awareness about the damaging effects of plastic waste on ecosystems, wildlife, and human health. Different organisations are observing  the day with elaborate programmes. The World Environment Day is the United Nations' principal vehicle for encouraging worldwide awareness and action for the environment. First celebrated in 1973, it has now become a widely recognised day celebrated in more than 100 countries around the globe. The day is celebrated every year on June 5 throughout the world with different themes to create awareness about the importance of protecting planet Earth and Mother Nature.

The Ministry of Environment has urged people to adopt environment-friendly practices in the management of sacrificial animal waste during the upcoming Eid-ul-Azha. Improper disposal of Qurbani waste and indiscriminate slaughtering of animals contribute to environmental pollution, pose health risks and cause suffering to the public, said a release of the ministry issued on Thursday. These challenges can only be addressed through active and conscious participation by everyone, it said. The ministry called on people to strictly use designated slaughtering spots specified by city corporations, municipalities and local government bodies, including district, upazila and union councils.  It also advised the public to avoid slaughtering animals in open or unauthorized areas. To ensure hygiene and safety, individuals involved in slaughtering and related activities have been asked to use personal protective gear such as gloves, masks and aprons.  Animal blood, dung and other waste should be buried in designated pits, and must not be discarded in open areas.  Waste materials—including hides, bones, entrails and horns—should be disposed of in designated bins or official waste collection points, the ministry added. Citizens have been encouraged to use biodegradable and eco-friendly bags or containers, rather than plastic, for distributing meat and removing waste.  Timely and hygienic waste disposal, with assistance from local authorities, is described as a civic and social duty.  

Environment Aviser Syeda Rizwana Hasan on Saturday urged the youth to steer clear of greed, the lure of power, financial irregularities, and corruption, and instead dedicate themselves to serve the nation. She made the call while speaking as the chief guest at a discussion titled "Manifesto Talk: Youth, Environment and Climate"at the Department of Environment in the capital. No scope for national election to go beyond  June next year: Rizwana Rizwana Hasan also formally inaugurated the Youth Climate Coalition during the event, said an official release. Calling for united action among young people to address the growing risks of climate change, she said, “Young people must work together to combat the challenges posed by climate change.” She said the government has taken three major initiatives—removal of outdated buses, introduction of electric vehicles, and a ban on establishing new brick kilns around Dhaka. The adviser said, “We want development, but not at the cost of nature. Filling up wetlands, cutting hills, and negligence in waste management must not continue. Development must be planned with respect for nature.” “Environmental protection is not the government’s responsibility alone; it’s everyone’s. Use jute or cloth bags when shopping. Safeguarding the environment is responsibility of all, not an individual one.” She proposed three model waste management projects for the north and south city corporations and emphasized the need for sustainable, biodegradable, and recyclable methods. “Single-use plastics must be banned without delay,” she asserted. She warned that the fires caused by waste piles in Aminbazar and Matuail pose serious public health threats. “These fires are increasing the risk of lung cancer for nearby residents. This issue must be addressed urgently,” she said. She stressed that old trees must not be cut in the name of road expansion. “Development plans must include tree preservation. The Forest Department and Public Works Department are working together to redesign the museum layout to save existing trees—this is a message of hope.” Others who spoke at the event included Mohammad Ejaz, Administrator of Dhaka North City Corporation; Ziaul Haque, Director of the Department of Environment; and Dr. Ahmad Kamruzzaman Majumder, Professor at Stamford University. Govt formulating plans to prevent further damage to rivers: Adviser Rizwana More than 300 young climate activists participated in the programme.  

The landslide that buried most of a Swiss village this week is focusing renewed attention on the role of global warming in glacier collapses around the world and the increasing dangers. How glaciers collapse — from the Alps and Andes to the Himalayas and Antarctica — can differ, scientists say. But in almost every instance, climate change is playing a role.  Dhaka’s air turns ‘moderate’ under influence of deep depression In Switzerland, the mountainside gave way Wednesday near the village of Blatten, in the southern Lötschental valley, because the rock face above the Birch Glacier had become unstable when mountain permafrost melted, causing debris to fall and cover the glacier in recent years, said Martin Truffer, a physics professor at the University of Alaska Fairbanks who studies how glaciers move. While the debris insulated the glacier and slowed melting, its weight caused the ice to begin moving — which accelerated dramatically a few weeks ago. Authorities ordered the evacuation of about 300 people, as well as all livestock, from the village in recent days, “when it became clear that there’s a whole mountainside that’s about to collapse,” said Truffer, who is from Switzerland. Glacial lakes pose threatLakes that form at the base of glaciers as they melt and retreat also sometimes burst, often with catastrophic results. Water can even lift an entire glacier, allowing it to drain, said Truffer, adding that Alaska’s capital of Juneau has flooded in recent years because a lake forms every year on a rapidly retreating glacier and eventually bursts. In 2022, an apartment building-sized chunk of the Marmolada glacier in Italy’s Dolomite mountains detached during a summer heat wave, sending an avalanche of debris down the popular summer hiking destination, killing 11. A glacier in Tibet’s Aru mountain range suddenly collapsed in 2016, killing nine people and their livestock, followed a few months later by the collapse of another glacier. There also have been collapses in Peru, including one in 2006 that caused a mini tsunami; most recently, a glacial lagoon overflowed in April, triggering a landslide that killed two. “It's amazing sometimes how rapidly they can collapse,” said Lonnie Thompson, a glacier expert at the Ohio State University. “The instability of these glaciers is a real and growing problem, and there are thousands and thousands of people that are at risk.” Scientists say melting glaciers will raise sea levels for decades, but the loss of inland glaciers also acutely affects those living nearby who rely on them for water for drinking water and agriculture. No way to stop the meltingScientists say greenhouse gases from the burning of fossil fuels such as coal have already locked in enough global warming to doom many of the world's glaciers — which already have retreated significantly. Global temperature likely to cross 1.5°C threshold within 5 years: WMO For example, glaciers in the Alps have lost 50% of their area since 1950, and the rate at which ice is being lost has been accelerating, with “projections ... that all the glaciers in the Alps could be gone in this century,” Thompson said. Switzerland, which has the most glaciers of any country in Europe, saw 4% of its total glacier volume disappear in 2023, the second-biggest decline in a single year after a 6% drop in 2022. A 2023 study found that Peru has lost more than half of its glacier surface in the last six decades, and 175 glaciers disappeared due to climate change between 2016 and 2020, mostly due to the increase in the average global temperature. A study published Thursday in Science said that even if global temperatures stabilized at their current level, 40% of the world's glaciers still would be lost. But if warming were limited to 1.5 degrees Celsius (2.7 degrees Fahrenheit ) — the long-term warming limit since the late 1800s called for by the 2015 Paris climate agreement — twice as much glacier ice could be preserved than would be otherwise. Even so, many areas will become ice-free no matter what, Truffer, the University of Alaska expert. “There's places in Alaska where we've shown that it doesn't take any more global warming,” for them to disappear, Truffer said. “The reason some ... (still) exist is simply because it takes a certain amount of time for them to melt. But the climate is already such that they’re screwed.”  

The fashion industry, which has always been praised for its productive and cultural contributions, has turned into one of the most environmentally damaging sectors in the world. Its impact stretches across natural resources and climates. From piling up in masses in landfills, polluting and clogging water, and making air unbreathable to destroying the balance in the earth’s resources and atmospheres, fashion waste is making life impossible on the planet. What is Fashion Waste? The term fashion waste refers to the useless materials naturally produced during the manufacturing of textile products and thrown away afterwards. It also includes worn-out clothes and other materials like wastewater, plastic waste, and toxic dyes discarded or discharged after their use. Though the term fashion waste mostly highlights the wastage related to garments and fabrics, it has more branches. Any poisonous discharge of non-biodegradable waste that pollutes energy and natural elements like earth, water, and air during or after the manufacturing and use cycle of garment products falls under the definition of fashion waste. Read more: How to Declutter Your Wardrobe to Donate Some Clothes Key Environmental Impacts of Fashion Waste . Landfill Overflow Much of the fashion waste is synthetic fibres such as polyester, nylon, and acrylic. These elements take about centuries to decompose and mix with soils or never decompose. There are many regions on the earth where miles after miles have been occupied by them. Massive piles of non-biodegradable materials are slowly eroding away, releasing poisons into the soil and air, making those regions unlivable. In 2018, the US single-handedly generated about 11.3 million tonnes of textile waste, about 66% of which ended up in landfills. Water Clog and Pollution Fashion waste contaminates water in two ways: chemically transforming its nature and clogging it with insoluble materials like plastic. Among chemical polluters, textile dyeing is the world's most common and second-largest water contaminant. Several rivers in Bangladesh and India, such as the Buriganga and Ganges, are carrying the mark of the devastating impact of textile waste. Synthetic and plastic materials cause water clogs, impeding usual flow and preventing water from passing. They are the primary reason for clogged drains and sewerage. Synthetic clothes are also known to release microplastics into water during washing or when dumped in a water body. These microplastics are invisible, insoluble fibres that travel with river currents and fall into oceans, where they accumulate in large amounts and are consumed by marine life.  Read more: How to Choose the Best Fabric for Your Suit Greenhouse Gas Emissions Dumped clothing waste in landfills doesn’t only pile up and occupy spaces; during decomposition, it releases methane, one of the primary catalysts of the global greenhouse effect and about 25 times more potent than CO2. Studies have found the fashion manufacturing industry to be highly energy-intensive. To manufacture a single shirt, about 2,700 litres of water are needed, and 2.1 kg of CO₂ is emitted. A pair of jeans produces 33.4 kg of CO₂ in their cotton cultivation and dyeing phases. At the current production acceleration rate in the fashion industry, the emission rate will increase by about 50% by 2030 without interference from regulatory bodies. Resource Depletion The fashion industry is one of the most resource-depleting sectors. For example, cotton covers around 2.5% of the world’s farmland and consumes about 24% of all insecticides and 11% of pesticides. That’s a huge environmental cost for a single crop. Then there’s polyester, the most common fabric in today’s clothing, found in about 60% of garments. It’s made from crude oil, tying fast fashion directly to fossil fuel depletion.

The dyeing and finishing stages of textile production are some of the most chemically intensive and responsible for nearly 20% of global industrial water pollution. Around 43 million tonnes of chemicals are poured into the process each year. 

Bangladesh has stressed the urgent need for a coordinated regional approach to effectively combat plastic pollution, highlighting the importance of collective action to address the growing environmental threat. “South Asia, home to some of the world’s most important river systems, is facing a growing plastic pollution crisis. Plastics cross borders, accumulate in our shared waters, and threaten ecosystems and livelihoods alike. This calls for a coordinated regional strategy built on cooperation, innovation, and sustainable financing,” said Environment Secretary Dr Farhina Ahmed. Rizwana calls for positive mindset in environmental actions The secretary made the call while speaking at a high-level panel discussion on “Policy and Regulatory Challenges of Managing Plastic Waste” in Colombo, Sri Lanka on Monday. Farhina led a three-member Bangladeshi delegation at the discussion. She outlined three core reasons behind the region’s ongoing struggle to manage plastic waste: inadequate waste management practices including open dumping and burning; weak enforcement of existing policies; and limited regional cooperation on data sharing and joint monitoring, the release added. Farhina called for the formulation of a South Asian Regional Multisectoral Plastic Action Plan, featuring harmonised policies for a circular economy, unified regulatory standards to reduce plastic generation, and alignment with the Global Plastics Treaty.   She proposed strengthening the recycling value chain through collaborative waste collection, sorting, and investment in innovative recycling technologies. Bangladesh also urged South Asian nations to phase out hazardous plastics and additives while promoting safer, recyclable alternatives.  A regional plastic waste tracking system and targeted clean-up programs for legacy plastic hotspots were proposed to improve governance and accountability. She highlighted the need to enhance law enforcement to curb illegal plastic dumping and trans-boundary leakage. This is what forecasters mean when they talk about a 100-year flood The secretary emphasised the importance of South Asia-specific research, public-private partnerships for sustainable packaging, and digital tools like AI-driven waste monitoring. “Solutions imported from elsewhere may not work here. We must invest in innovation tailored to our region.” The Plastic-Free Rivers and Seas Roundtable brought together high-level government officials, policy experts, and environmental leaders from across South Asia to forge a united path toward tackling plastic pollution in trans-boundary water systems.

Authorities and environmentalists in Zambia are concerned about the long-term effects of an acid spill at a Chinese-owned mine that polluted a major river, potentially impacting millions of people after pollution signs were detected over 100 kilometers (60 miles) downstream. The incident occurred on February 18, when a tailings dam at a northern copper mine, which stores acidic waste, collapsed, according to investigators from the Engineering Institution of Zambia. Dhaka air ‘unhealthy for sensitive groups’ Sunday morning This collapse released around 50 million liters of toxic waste, containing concentrated acid, dissolved solids, and heavy metals, into a stream connected to the Kafue River, Zambia's main waterway, the institution reported. “It’s a catastrophic environmental disaster,” said Chilekwa Mumba, an environmental activist from Zambia's Copperbelt Province. China is a key player in Zambia's copper mining industry, with Zambia being one of the world’s top 10 copper producers, a critical material in smartphones and other technology. Zambian President Hakainde Hichilema called for expert assistance, acknowledging that the leak poses a crisis threatening people and wildlife along the Kafue River, which stretches over 1,500 kilometers (930 miles) through central Zambia. The full extent of the environmental damage is still under investigation. A river died overnight An Associated Press journalist visited the Kafue River, where dead fish were seen washing ashore about 100 kilometers (60 miles) downstream from the mine operated by Sino-Metals Leach Zambia, majority-owned by the state-run China Nonferrous Metals Industry Group. The Ministry of Water Development and Sanitation confirmed the "devastating consequences," which included the destruction of crops along the river's banks. Authorities also worry that groundwater could become contaminated as the mining waste seeps into the soil or spreads to other areas. “Before February 18, this river was thriving,” said Sean Cornelius, a local resident, describing how fish died and birdlife vanished almost immediately. “Now it’s completely lifeless, like a totally dead river. It’s unbelievable. It died overnight.” How Green Industries Can Reduce River Water Pollution in Dhaka City Around 60% of Zambia’s 20 million people live in the Kafue River basin and rely on it for fishing, agriculture irrigation, and industrial water. The river provides drinking water to around five million people, including in the capital, Lusaka. The acid spill caused a complete shutdown of the water supply to Kitwe, a city of around 700,000 people. Efforts to reverse the damage In response, the Zambian government has mobilized the air force to drop hundreds of tons of lime into the river to neutralize the acid. Speedboats are also used to apply lime along the river. Government spokesperson Cornelius Mweetwa called the situation “extremely serious,” adding that Sino-Metals Leach Zambia would be responsible for the cleanup costs. Zhang Peiwen, chairman of Sino-Metals Leach Zambia, met with government officials this week and apologized for the spill, according to a transcript released by his company. “This disaster has raised a major alarm for Sino-Metals Leach and the mining industry,” he stated. “We are committed to restoring the affected environment as quickly as possible.” Discontent with Chinese presence The environmental impact of China’s vast mining operations in mineral-rich parts of Africa, including Zambia’s neighboring countries Congo and Zimbabwe, has faced significant criticism, even as the minerals are vital to the economies of these nations. Chinese-owned copper mines have been accused of disregarding safety, labor, and other regulations in Zambia while attempting to control the country’s copper supply. This has led to discontent with their presence. Zambia also has over $4 billion in debt to China, and the country had to restructure some of its loans after defaulting in 2020. A smaller acid leak from another Chinese-owned mine in Zambia’s Copperbelt region was discovered shortly after the Sino-Metals incident, with authorities accusing the smaller mine of trying to conceal it. Local police reported the death of a mine worker who fell into the acid, and alleged that the mine continued operating despite an order from authorities to cease operations. Two Chinese mine managers have been arrested. Both mines have now halted operations following orders from Zambian authorities, though many locals remain angry. Powerful March storm sparks wildfires, causes fatalities, raises Tornado concerns “This highlights the negligence some investors have toward environmental protection,” said Mweene Himwinga, an environmental engineer who attended the meeting with Zhang, government officials, and others. “They seem to have no concern or regard at all. This is worrying because, at the end of the day, it’s the only land we have as Zambians.”
