Environment pollution and its remedy.

Introduction: The dim blue sky is in space.
His neighbors are moving like planets, satellites and stars. People are ruining the nature in different ways.
He's unknowingly killing his own ax.
Making the air, air, soil, and toxic water.
Greenhouse gases are coming to the Earth today.
There was a parallel between nature and environment on the life and livelihood that was created millions of years ago. The role played in maintaining this balance was nature and environment. On the path of evolution of civilization, people have developed a little bit of their own environment. Human evolutionary environment is the evolution of its civilization crop. People have gathered with the talent, hard work and expertise of their new discovery, various methods of science and technology. Has acquired many tools for life-building. So he has made his own needs and interests according to his environment. Within this environment, its development, its destruction signals.
Reasons for environmental pollution: Population growth is one of the reasons for environmental pollution. Due to the increase in population, natural resources have accumulated over water, soil, and air. Amit festivities of forest resources destroyed The plant world and the creatures of the world have also been affected. The balance of nature and environment has reached a crisis situation. It has been associated with rising demand for energy production. With energy production, the emissions of human health and environment-contamination of various chemical products emerge. Malicious chemicals are the reason for the rapid expansion of many incurable disorders. The air-water-food is being severely polluted.
Air pollution: Air pollution in Bangladesh is not free from pollution. This problem is the highest in Bangladesh's capital Dhaka. There are mainly two reasons behind air pollution in Bangladesh. Firstly: the smoke of the factory and secondly: the smoke of the vehicles. Fumes, emissions, sugar, paper, jute and textile mills, tanneries, garments, chemical and pharmaceutical industries have a lot of smoke. In Bangladesh many other health problems arise from headache, such as Hazaribagh tannery, emit hydrogen sulphide, ammonia etc., from poisoning caused by chemicals.
Increasing urbanization in the country, increasing vehicles increasingly contributing to air pollution. Excessive smoke emanates from two-stroke lanes like Baby Taxi, Tempo, Motor Cycle, Trolley etc. Besides, 90% of vehicles in Dhaka city are faulty, which are harmful for the environment. Recently, the government has decided to ban more than 20 years old vehicles.

The normal components of the gas in the air are: Eitogene 78.084% Oxygen 20.946% Argon 0.9340% Carbon-dioxide 0.0383%

Short term issues:
Due to air pollution, eye and nose pain is in short term. There are also serious diseases like bronchitis and pneumonia.
Long-term problems: Short-term breathing, lung cancer, heart problems, and even brain, nerve, liver and kidney failure can be broken due to air pollution.
Health Problems of Air Pollution: Air pollution can affect our health both short and long term. No one is free from air pollution, but children and older people are more damaged. Problems with asthma, heart and lung problems caused by air pollution.
Due to air pollution, eye and nose pain is in short term. There are also serious diseases like bronchitis and pneumonia.
Long-term problems: Short-term breathing, lung cancer, heart problems, and even brain, nerve, liver and kidney failure can be broken due to air pollution.
Water pollution: Another name for water is life. 65% of human body water 71% of the Earth's water. But water pollution is constantly causing water pollution. Due to the contaminated drinking water, there are many prevalent complications.
Due to water pollution: Water is polluted in different cities and towns in Bangladesh. The causes of water pollution are mentioned below:
In urban areas: The water supply in the city is mainly from the surrounding rivers. The water is purified to be eaten and useful. The reasons for water pollution in the city are:

1. Water pollution in the fields of the waste is polluted.
   2.The illegal pollution system on WASA water line and they pollute water in the water.
2. Sometimes the water line bursts and it enters the dirt-garbage inside. As a result, the water is contaminated.
   In rural areas, people use water, ponds and water bodies for eating and using in rural areas. In many ways the water is contaminated. The reasons given below are:
3. Arsenic is the main cause of water pollution in the water of tube well.
4. The use of pesticides in the field of crops and water in the pond, polluted water is contaminated with pond water.
5. In the same pond, the water is contaminated by cleaning the clothes of people, cattle and cattle.
   Thus the water in the city and the village is polluted and the food and consumption become inefficient.
   Health risks of water pollution: Water pollution causes different types of water borne diseases. For example,
   Water borne disease: diarrhea
   Bacterial: Typhoid
   Infections: cholera, paratyphoidal and basilic dysentery
   Viral infection (jaundice): Polioemilitis hepatitis infection
   Protozal infection: The amoebic dysentery
   Sound pollution: Sound pollution is one of the important, widespread problems of this era. The problem is increasing day by day. The noise level in the city is highest. There is a great deal of generosity in the production of an oasis in the heart of the motorbike, the sound of the factory, the sound of the fire, the radio, the sound of the television, the shouting of the people, the drowsiness of the festival, the melody of the music. The result of noise pollution is horrific.
   There are many sources of sound pollution and many types. Without proper reason, the microphone or cassette player should stop playing. Needless to stop playing horns and playing hydraulic horn legally. In residential areas, so that factories can not grow, they have to be arranged. According to the Forest and Environment Act 1997, the area up to 100 meters from hospitals, educational institutes, and some other institutions have been identified as a silent area. Human awareness is the highest in terms of noise pollution.
   Dhaka is now a city of noise pollution. After lifting two stroke-related auto-rickshaws in Dhaka from the city of Dhaka in 2003, along with air pollution, the level of noise pollution decreased relatively, resulting in some respite from the city dwellers. But their comfort did not last long. People who do not understand the consequences of noise due to noise pollution are long-term, people do not understand the consequences of it immediately. So, there are fewer people's attention too. Due to this, residential areas of Dhaka, hospitals, educational institutions, nothing is being avoided, the vehicles of the hydraulic horn, the loud sound of the factory, the sound of Mike and CD player.
   The noise of noise pollution: Sound pollution that not only creates irritability but also closes the human body's arteries, increases adrenaline movement and forces the hutpind to work fast. Increasing the risk of heart attack and stroke if there is a continuous high sound. According to expert doctors, noise pollution can cause nervous impediments. Experts believe that the continuous noise pollution spoils the hearing and causes permanent damage to the nerves. According to them, people living in the capital are under extra pressure on heart, kidney and brain. Children's temperament in noise pollution is irritable. They are losing hearing, losing their devotion. Its impact is on their education. Due to all types of noise pollution, sleep deprivation, hearing, emotional and physical health deteriorate. Any kind of noise pollution can harm pregnant mothers very well. Permanent mental impairment can occur in people with noise pollution.
   Radioactive pollution: The dangers of radioactive pollution among the most fundamental in nuclear war, nuclear weapons testing. In 1963 a US nuclear submarine was lost in the Atlantic Sea. A large amount of radioactive material spread from the natural environment. Nuclear energy production centers can survive for 600 years with its healing powers.
   Ways to prevent environmental pollution:
   People are part of the environment and enjoy the benefits. When the environment is in turmoil, people are shaken, human resources used to be destroyed, economic activity is interrupted. So there is a need to create a disaster-free environment to build healthy body and mind. Various measures can be taken to maintain environment and to prevent pollution; She-
6. Establish and implement national and international environmental policy.
7. Reduced population growth and significant reductions in the minimum level.
8. Ensure arrangements for every industry-factory that has environmental pollution.
9. Formulate comprehensive forestry program.
10. Public awareness was created to prevent sound pollution and to develop sound harmony.
11. Ensure industrial refining systems.
12. Banning the use of wood as a fuel. Innovate alternative fuel.
13. Prevent black smoke from vehicles and prohibit the use of high sound horn through proper rannabe.
14. Ensuring political pledge for regional and international cooperation in conservation of environment.
    | 10 Due to increase in traffic congestion on the roads, various problems including environmental pollution, accident, etc. are being created. As well as gradually increasing the new roads, the agricultural land is declining, due to the bridges and culverts of the roadway, barriers to river communication and water logging are increasing. Many of the river navigational routes have been identified as the cause of unplanned road construction. On the other hand, if the rail communication system was given priority, it would have been possible to transport more passengers and goods by polluting less energy and environment in a short space. Railways need priority in the transport system by tackling important issues such as tackling future energy crisis, protecting agricultural land, environmental pollution.
    So, to keep environment free of pollution, we need collective efforts. If necessary, to set up environmental courts and forest courts. Let us pledge to build our living environment. Our small efforts may be a great power.
    Conclusion: All countries are concerned about environmental pollution issues today. The existence of civilization has come in front of a crisis today. So in 1972, the United Nations Conference on 'the environment of the people' was held in Stockholm, in Stockholm. The 12-day Earth Summit was held in Rio de Janeiro, Brazil in 1992. Bangladesh's Constitution has also laid down the conditions for prevention of environmental pollution. Here also the World Environment Day is celebrated on 5th June every year. Today, environmental pollution predicts dangerous threat to human civilization. The need to prevent environmental pollution at any cost to make a secure world for future generations is undeniable.
