Lead (Pb) is an elemental heavy metal found naturally in the environment as well as in manufactured products. Lead can be released directly into the air, as suspended particles. Lead poses a severe threat to human health and the environment. Many populations have been exposed to environmental lead from paint, petrol, and mining and smelting operations in Bangladesh.
World Cleanup Day is one of the largest but the youngest civic movements. For the first time ever, on September 15, 2018, more than 18 million people from 157 different nations took part in simultaneous global cleanup efforts. Since then, the third Saturday in September has been designated as World Cleanup Day. To date, the cleanup movement has brought together millions of individuals in 180 different nations to clean up the earth.
The Montreal Protocol started as a global commitment to protect the ozone layer and is now one of the most effective environmental agreements ever. The Protocol was consented in 1987 as part of the Vienna Convention on Protection of The Ozone Layer, and the UN General Assembly declared September 16th the International Day for the Preservation of the Ozone Layer in 1994. Bangladesh has been recognising the day since 1990 following the treaty’s signing in the same year. The Kigali Amendment will make the Montreal Protocol an even more effective tool in the fight against global warming. The impact of the Kigali Amendment will avoid up to 0.5 °C increase in global temperature by the end of the century.
What is your aim in life? To such a question, school children easily answer to become doctors, engineers, lawyers, teachers, bankers or businessmen. But in today’s era of global warming, the mindset of working to protect the environment or thinking about issues like climate change does not move much in the minds of our students. Well, have we ever thought deeply about what are the limitations that lie ahead in realising our life goals? We think and believe that social or economic issues are our biggest limitations. But the reality is that the environmental degradation of the present world and the level of pollution in the developing countries are one of the main obstacles to reaching our goal. We may not think much that one of the causes of social and economic degradation is today’s environmental pollution.

The United Nations (UN) General Assembly’s Second Committee passed a resolution declaring September 7 as the “International Day of Clean Air for Blue Skies” during its 74th session. The theme for the International Day of Clean Air for Blue Skies’22 is “The Air We Share.” It emphasises the need for communal accountability and collective action by concentrating on the trans-boundary aspect of air pollution. The problem of air pollution is global and widespread. Air pollution is the largest contributor to the burden of disease from the environment and is one of the leading unavoidable causes of death and disease globally. Ninety-nine per cent of the world’s population is now breathing polluted air, warns WHO. Seven million people die each year due to air pollution, with 90 per cent of them in low and middle-income countries (WHO, the Lancet Planetary Health).

Plastic pollution in aquatic habitats is a significant environmental problem. It has severe influence on ecology putting aquatic species in danger. Riverine ecosystems are directly impacted by plastic pollution despite the fact that rivers are recognized a significant part in the transportation of land-based plastic garbage to the world’s oceans.
One of the present government’s greatest accomplishments is the Padma Bridge. Every source of pollution in the area has decreased because of the Padma Bridge. Additionally, the environment’s quality has improved. Numerous types of pollutants have been observed nearby in previous years. Meanwhile, the area around here is green and clean. It has major ecological significance.
