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 and various reactions:

There are also variations in the nature and method of pollution. One of the main components of our natural resources is air. That air pollution is around the world today. This is a serious problem for everyone's health. The amount of carbon dioxide in the air is increasing continuously. As a result, the temperature is increasing in the climate. This is the result of sudden rain, storm and fog. The cultivation of such weather is uncertain. Fog and oil, the combination of gas emitted by the coal burning, and the smog. Its harmful power is deadly. Headache, respiratory failure, asthma, chronic bronchitis, lung cancer, and the result of such pollution. The smoky smoke of different vehicles comes in contact with the sunlight and the light chemical smog. Some air pollutants are produced in the reaction of oxide and hydrocarbons.
Water Pollution:

Water Pollution Another Curse of Modern Civilization The waters of the world's oceans, rivers, ponds, canals, etc. are being polluted in many ways. On the banks of the river, rich populations, cities. It has been established in modern artillery, textile, coal bleaching, sugar mills, paper mill, herbal oil making factory, leather-making factory etc. The waste of these factories is regularly polluting the river. Alkali, ammonia, cyanide, naphthalene, phenol and various chemical pollutants are present in various industrial areas every day. The water of almost all the rivers of Bangladesh in the confluence of pollution Tanks, sewage and house debris etc. are responsible for pond, canal-bill pollution. It is contaminated soil, polluted drinking water There are also many pollution in the rivers of the river Khalabi pond. Different types of infectious diseases are spreading. Occasionally it has the epidemic. How many lives do death take away? This is why public health is being destroyed day after day.
Noise pollution:

Sound pollution is an important, widespread problem 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. Shabad is the source of 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 should be arrangedAccording 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 consciousness is the biggest one to prevent noise pollution. Now the 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 sound of the hydrological horn of the vehicle, the loud sound of the factory, the sound of Mike and the CD player.Sound pollution not only creates irritability but also stops 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 risk of radioactive pollution in nuclear warfare, nuclear weapons testing is the most vulnerable. 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 center can survive for 600 years with its healing powers.The world's civilized people are afraid of the terrible consequences of pollution. Think about the possible ways to deal with this terrible problem, the plan does not end. To reduce the amount of pollutants emitted by controlling the combustion process, it has been taken for the treatment of air pollution. It has been taken without planting plan. One study found that, through forestry alone, it is possible to protect almost all types of environmental pollution. To make polluted water drinkable, there is a need for suitable fertilization. The main way to reduce the effectiveness of sound pollution is to use anti-cellular cells. In recent developments of technology, some methods have been invented so that the garbage control of nuclear reactors is possible. This will not be radioactive in the environment of nuclear power plants.

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.
