The Global atmosphere has shifted dramatically over time. In the previous 650,000 years, there have been seven glacial advancement and retreat cycles, with the abrupt conclusion of the last ice age part of the launch of the climatic period – and human advancement. A substantial portion of these climatic changes is caused by minute differences in the earth’s gravity, leading to an excess of solar energy that is obtainable to the earth.
Unsustainable environments and ecosystems are the Main causes all over the world that sluggish our economic development, hinder our country’s development. Likewise, Bangladesh is also being influenced due to climate change, especially in the seashore regions, people will be submerged after a few years. Many kinds of hazards increase due to climate changes such as increasing unnecessary death and injuries as well as raising personal resources and economic losses. Poor and vulnerable communities especially those who are living over seashore are leaving their homestead because of the increasing incidence, rising severity of disasters such as cyclones, landslides, floods, and other natural disasters. According to a recent UNICEF report, ‘over 9 million children across Bangladesh are hunted by the fires of climate change.’ they lost their homestead after rising sea level. They have been suffering and striving for their basic needs.
Bangladesh is one of the world’s most sensitive countries to climate change risk, particularly cyclones and floods, according to the GCF research, and coastal regions are in danger of extreme weather. (GCF Annual Report, 2022). Ecosystem for resilience but has to face difficulties and has to compete with elasticity due to climate changes. The capacity of our ecological system reducing and environmental degradation that has been implementing ominous roles to communities like firewood, medicine, food, and protection from natural disaster have been reducing our landscape’s ability unprecedentedly.
Many scientists think that crucial carbon and unplanned waste management is causing this destruction. If climate change proportion is going as much as unexpectedly, it will be outcomes from an intense disaster for Bangladesh and its people. Some reasons are mainly victimized from the perspective of Bangladesh, such as Implanted management of plastic waste, growing population exacerbated scarcity of food and shelter, unsustainable industrial development, lacking pure water supply, etc. Among them, the laming plastic waste management system and air pollution cause harm to people ominously.
Recently, a report published by the World Bank here said, in the last 15 years, Bangladesh’s annual plastic consumption reached triple in the urban areas. A great number of plastic wastes are dropped into water bodies and rivers. The implanted management system of plastic waste is contaminating rivers, canals, and also polluting cities, it is happening because of clog dragging. Plastic is a slow-dreg material that poses a significant risk to humans, the environment, and our ecosystem. According to a report of the World Bank, Dhaka is the second-highest polluted city in the world. The annual per capita of plastic consumption stood at 22.25 kg. About 646 tons of plastic waste is daily collected from Dhaka, and the survey says only 32% of plastic waste is recycled.
Although, the average plastic consumption of Bangladesh’s people are not more than European countries. However, Bangladesh has been becoming the top plastic waste country due to its mismanagement. If we look at the developed countries, we will see their envelope projects are fundamentally based on sustainability. Several governments and non-government organizations designed research-based sustainable models to overcome this complex situation, like water efficiency projects, green public building projects, renewable energy projects, green transportation planning, sustainable urban planning, waste management, recycling projects, childbirth, and population under control projects.
Recently, a waste management project was invented by a Dhaka university’s bio-chemical engineering students. HM Ranju and Pijush Dutta show how to convert waste into resources. We can produce different types of chemical flue gas, liquid organic fertilizer, oil, etc. Government should appreciate and implement it. Therefore, stimulation of research among young people will be increased as well as the earth will be safer for us. Air pollution is the biggest problem for Dhaka, to protest them we can think we should take some action such as over bridge build, disuse vehicles prevention, sustainable vehicles launch, etc. Climate change and ecosystem reduction, disaster will come as a demon over Bangladesh. Without sustainable management, conservation, and restoration of ecosystems and deserting risk by mitigating hazards and increasing livelihood, ecosystem resilience will be impossible to improve.
