Water Pollution Of Bangladesh

Water, an important element of the human environment, is essential for human and plant life. It is next to air. Water can be polluted in many ways. Farmers use chemical fertilizers and insecticide in their fields to grow more food. The rain and floods wash away some of the chemicals. They get mixed with river water, canal water and pond water. Mills and factories pollute water by throwing the waste materials and unsold products into the rivers and canals. Steamers, motor launches and even sail boats can pollute water by throwing oil, food waste and human waste into the rivers and canals. Unsanitary latrines in the countryside standing on the bands of the rivers and canals cause water pollution. Clean water is safe for use and polluted water is harmful for man.

Water Pollution

 Water pollution can be prevented in many ways. First of all we should make the people aware of the fact that water is next to air. It is called life. So chemical fertilizer and pesticide should not be allowed to mix with river water, canal water and pond water. Mills and factories should not throw the waste materials and unsold should not throw oil, food waste and human waste into the rivers and canals. Unsanitary latrines in the countryside should not be built on the bands of the rivers and canals. In fire awareness should be created in the public.

Deforestation Of Bangladesh

Deforestation means cutting down trees in large number. The causes of deforestation are many. Bangladesh is the most densely populated country in the world. Its population is much more in proportion to its area. This huge number of population needs more shelter, agricultural land, fuel, furniture etc. For all these reasons people cut trees. Moreover there are some dishonest people who cut trees in our forests to make money. They effects of deforestation are too many to describe. This destruction disturbs our ecological balance. The existence of animals are going to be threatened. Due to deforestation carbon dioxide is increasing worldwide. As a result, the world is becoming warmer. The sea level is rising and many parts of the world is going to be engulfed by the sea in recent future. On the other hand, new areas of the world are turning into deserts as a result of deforestation. The removal of trees causes birds and other animals living on them to leave the place. It also causes serious damage to the soil, as trees give protection to soil as well. In the end, the soil gets sediment in the river bed and causes frequent floods. So, if we destroy trees at random. 

One day the country will turn in a great desert. All living animals and birds will not find any food or shelter to live in. They will be destroyed. There will be no rain and as a result our agriculture will face a great crisis. The temperature will rise and it will cause green house effect. The country will be unsuitable for living and various natural calamities like flood, drought, storm etc. will visit our country. Tree plantation program should be extended throughout the country.

Acid Rain Of Bangladesh

Acid rain is a such kind of rain which contains harmful chemicals. But in severely polluted areas, rain can be as acidic as the acids of lemon juice or vinegar. This rain, which is very acidic, can cause damage to trees, lakes, wild life, building and human health. Acid rain also damages to human health. Breathing in chemicals can harm people. It causes chest illness. When acid rain causes the release of chemicals and metals into drinking water, it polluted the water. That is how acid rain affects drinking water. Fading of the colors of the glass is a common result of the acid rain. It is very defected for human body. All of these approaches probably have a role to play, but all have some disadvantages which will form a research agenda for the next few years.

Origin of Acid Rain

In the last thirty years some 1000 years old stained glass windows have been damaged by acid rain. The damage of Big Building indicates that acid pollution is occurring in the developing world.

Waste Of Management Of Bangladesh

Waste of rubbish is what we throw away everyday. It includes everything from unwanted old cars to cigarette packets. As the amount of waste is growing rapidly all over the world and polluting the environment, the time has come to think about it very seriously. We cannot altogether get rid of our waste, but  a proper management of it can certainly reduce it. If we think of burning, burying, recycling and thus reducing our waste. We can save our environment to a large extent. We can use some waste as fuel. We can use vegetable waste to make compost to improve our soil.

In many countries it is now quite normal to collect old bottle and cans and recycle them. More and more companies should come forward to promote greater recycling and changes in consumption patterns to reduce the amount of rubbish and help people. So we should do the right thing at the right moment because timely action brings for us great success and saves us from a lot of troubles. Moreover, we know prevention is better than cure. So it is high time to take proper steps and necessary measure to raise awareness about the problem of waste management.

Natural Disasters Of Bangladesh

When a storm revolves violently round a centre, it is termed a cyclone. It moves at a high speed ranging form forty to one hundred or more kilometers per hour. A cyclone varies in diameter from eighty to one hundred or more kilometers. During the last four years, several devastating cyclones swept over Bangladesh and cause immense harm to the people. This extreme weather condition is a curse, especially to the inhabitants of the coastal regions of Bangladesh. A cyclone may occur any time and at any place. The violent types of cyclone usually hit the tropics. The cyclone of Bangladesh generally originates from the Bay of Bengal, and blows towards that land. It is often accompanied by thunders and heavy showers. Before a cyclone commences unbearable heat is felt for a few days. Then suddenly one day the sky becomes terribly dark with clouds and strong winds begin to blow with flashes of lightning and the rumbling of thunders. Thus a terrible situation is created that lasts for a few hours. It causes a great havoc. A lot of people and other animals die. Dwelling houses are blown away. The tidal bore and the heavy showers wash away the stores of food stuff and leave the marks of terrible damage.

The cyclone is usually followed by scarcity of food and out break of various diseases such as cholera, dysentery, fever etc. Which spread all over the affected areas. However, the great loss caused by cyclones can be reduced to a substantial extent. Using modern technology's of weather forecast. Prior warning can be given to the people who are likely to be affected by the cyclone. This people and their domestic animals can be shifted to the cyclone shelters. Moreover, a quick relief, medical treatment and essential medicines should be made available to the affected people just after a terrible cyclone.

Radio As a Medium Of Education In Bangladesh

The child learns to talk as it learns languages, singing and many other things by listening to others by listening to others. Educational is broadcasting is only a shape of this idea. History is presented in the form of dramas, geography is told in the form of travels and poetry is recited. This creates a special interest in the heart of the children.Radio has conquered the distance of time and space. So the students can hear over the radio and know the speeches of the great men who aren't in their midst. The talks of the experts, either foreign or home, may be relayed from different centres.

Education of the masses may be carried on successfully through radio. The illiterate people can thus know many things regarding health, agriculture and other objects of their household affairs. The businessmen can know many things through radio regarding their business affairs. Army education is also a great boon of radio.But we have great difficulty in this respect. Most of the schools of our country have no receiving sets. Government should chalk out plans to provide the schools with receiving sets.

Cyclones In Bangladesh

The cyclone is a severe calamity. It visits Bangladesh almost every year. It lasts for a short time but is more terrible than the flood. It comes by surprise and passes over very quickly. The whole area over which it passes are affected very badly. The cyclone blows very hard in a circular motion and moves round the center. It passes with a great fury and changes its motion gradually or suddenly. 

The low depression in the Bay of Bengal is the cause of cyclones in Bangladesh. This may take place far away from the main land. But it approaches the main land at a great speed and lashes the the trees, houses and every thing in it's way.

Before the cyclone begins, there appear patches of clouds together with gusty winds. As the cyclone approaches clouds pass very swiftly in the sky. The wind becomes gradually harder and grows more and more forceful and violent. When the cyclone actually appears, the whole sky looks like a dark sheet of clouds. The stormy wind passes very speedily with a deafening sound. It rains in torrents. Roofs of houses are blown away. Trees of all sizes are uprooted, boat, launches and ships capsize. These sink down with goods and passengers. The cyclone is a horror to all. It causes great loss of life and property.

Floods Effect In Bangladesh

Floods in Bangladesh do great damage to crops. Sometimes houses are swept away, trees are uprooted and callte are destroyed in large numbers. During the last a few years several floods swept over our country. They caused great havoc to lives and properties and brought about untold sufferings to the people who survived. The floods of 1954 were the severest of all recorded in history. Many people died and many were rendered homeless. Their misery knew  no bounds. Devastating floods also hit Chittagong in1961, Barisal in 1965, Rangpur and Dinajpur in 1968 and almost all the districts in1970, 1974 and 1988.

A well- planned irrigation system will go a long way to reduce the extent and fury of such terrible floods. Embankments are being constructed to put a stop to their frequent visit. Our beneficent Government shall surely find out permanent ways and means to check them.

Floods In Bangladesh

It is popularly believed that flood is a curse and it comes as a punishment when we sin against Allan. but excessive rainfall is the real cause of flood. In the rainy season it generally rains without break. Pools, canals and rivers are all filled up and can hold no more water. So it overflows the banks and stands on the ground. As a result fields and roads go under water to the great hardship of all. This is called flood.

Our Bangladesh is a plain, low land. Many rivers wind over her bosom. So floods visit our country almost every year. When the monsoon begins there is excessive rainfall. The rivers swell to an alarming extent. They overflow their bands and wash away the lands on both sides. The sudden melting of snow or the sudden visit of tidal waves makes the rivers overflow and causes floods. Again they overflow their banks, causes floods and damage crops. They send water in the villages and as a result, fields and road go under water.

The Peasants Of Bangladesh

Bangladesh is mainly an agricultural country. Her people directly or indirectly depend upon agriculture for their living. So most of them are peasants.

The peasants of our country are generally uneducated. They are religious and God fearing by nature. They are simple in their habits and have sympathy for one another. There was a day when the economic condition of our peasants was good. They lived happily and peacefully. But with the growth of towns the state of things has changed for the worse. Most of them lead poor lives. Their children are ill- clad and ill- fed. They have no means to send their children to schools. They fall ill and die in numbers without diet and medicine. The peasants of our country have to work all day long. They till the land and make it ready for sowing seeds of different crops. They pull out the weeds from the land under crops. Sometimes they have to keep busy whit their work from morning till night and cannot make time to have their midday meals. With all this they are poor and illiterate. Though they are the feeders of the people, their children very often go without food.
