Environment Pollution (250 Words)

Introduction

The environment is the world around us in which we live and breathe. It includes the air, the water, the soil, the plants and the animals. When any of these parts becomes dirty or poisoned by harmful substances, we call it environmental pollution. Today pollution has become one of the most serious problems of the modern world, and Bangladesh, with its dense population and growing industries, suffers from it greatly.

Causes

Pollution has many causes. The air is polluted by smoke from vehicles, brick kilns and factories. Water becomes impure when waste, sewage and chemicals are thrown into rivers and ponds. Soil is spoiled by the overuse of chemical fertilisers, pesticides and by heaps of plastic waste that do not rot. Cutting down trees and the noise of horns and machines add further harm to nature.

Remedies

We can reduce pollution if we all take care. Factories should treat their waste before releasing it, and vehicles should be kept fit. We should plant more trees, use dustbins properly and avoid burning rubbish. The government must enforce the laws strictly, while schools and the media should make people aware of the dangers.

Conclusion

A clean environment is essential for a healthy life. Pollution is a problem created by us, so it can be solved by us. If every citizen becomes conscious and works together, we can keep our environment safe for ourselves and for the generations to come.

Introduction

Environment means the natural world that surrounds us — the air we breathe, the water we drink, the soil we grow our food in, and the plants and animals that share the earth with us. When harmful things pollute these elements and make them unfit for use, the result is environmental pollution. It has become a burning question of our time, and a densely populated country like Bangladesh feels its effects every single day.

Air Pollution

Air is polluted mainly by smoke and poisonous gases. In cities, buses, trucks and cars give off dark fumes, while brick kilns and factories send up thick smoke. Burning rubbish and the dust of unpaved roads also make the air heavy and unhealthy. Breathing such polluted air causes coughs, asthma and other diseases of the lungs.

Water and Soil Pollution

Water pollution is a great danger in our country. Mills and factories drain their untreated waste into rivers, and household sewage flows into ponds and canals. As a result, fish die and drinking water becomes unsafe. Soil, too, is being harmed. The excessive use of chemical fertilisers and pesticides weakens the land, and plastic bags thrown here and there choke the soil because they never decay.

Effects and Remedies

Pollution damages our health, destroys wildlife and disturbs the balance of nature. It even changes the climate and brings floods and unusual weather. But the problem is not beyond cure. Factories must set up treatment plants, and vehicles must be kept in good condition. We should plant trees on a large scale, use dustbins, and say no to polluting materials. The government should apply environmental laws firmly, and every citizen should be made aware of the harm pollution does.

Conclusion

Environmental pollution is a man-made problem, and therefore we ourselves hold the key to its solution. A clean and green environment is the birthright of every human being. If we act now, with knowledge and unity, we can leave behind a healthier and safer world for our children.

Environment Pollution (600 Words)

Introduction

The word environment refers to everything that surrounds a living being — the air, the water, the soil, and all the plants and animals of the earth. These elements work together in a delicate balance that makes life possible. When this balance is disturbed by harmful and poisonous substances, we say the environment is polluted. Environmental pollution has now become one of the gravest problems of the modern age, and Bangladesh, being small in area but huge in population, suffers from it more than many other lands.

Air Pollution

Among the different kinds of pollution, air pollution is perhaps the most widespread. The smoke of factories, brick kilns, buses, trucks and cars fills the sky of our cities with poisonous gases and fine dust. In Dhaka the air often turns grey and heavy, especially during the dry season. Burning of waste and the black exhaust of old vehicles make matters worse. Such foul air causes coughs, headaches, asthma and other diseases of the heart and lungs, and it is especially harmful to children and the elderly.

Water Pollution

Water pollution is another serious threat in our riverine country. Mills, tanneries and factories pour their untreated chemical waste directly into rivers such as the Buriganga and the Turag. Household sewage, farm chemicals and rubbish also drain into ponds and canals. As a result, the water turns black and foul, fish die, and people who drink or use it fall ill with diarrhoea and skin diseases. Since we depend so heavily on rivers for fishing, farming and daily use, polluted water strikes at the very heart of our life.

Soil Pollution

The soil, which gives us our food, is also being spoiled. Farmers use chemical fertilisers and pesticides beyond measure to grow more crops, but in the long run these poisons weaken the fertility of the land. Plastic bags and other non-degradable waste are thrown carelessly and mix with the soil, where they remain for years without rotting. This slowly reduces the power of the earth to produce healthy crops.

Effects

The effects of pollution are far-reaching. It ruins public health, kills fish and wildlife, and disturbs the natural balance of the seasons. The cutting down of forests together with rising smoke adds to global warming, which causes irregular rainfall, floods and rising sea levels — a special danger for a low-lying country like Bangladesh.

Remedies

Fortunately, pollution can be controlled if we act wisely. Factories should be bound by law to treat their waste before releasing it. Vehicles must be kept fit, and cleaner fuels should be encouraged. We should plant trees in large numbers, use dustbins, and avoid burning or scattering rubbish. Above all, people must be made aware through schools, mosques and the media, and the government must enforce environmental laws strictly.

Conclusion

Environmental pollution is a problem of our own making, and so its cure also lies in our own hands. A clean, green and healthy environment is not a luxury but a necessity for survival. If every one of us becomes conscious and works together, we can protect our beautiful land and hand it over safe and sound to the generations yet to come.

Environment Pollution (800 Words)

Introduction

Environment means the whole of the natural world in which we live — the air we breathe, the water we drink, the soil that grows our food, and the countless plants and animals that share the earth with us. All these parts are joined together in a fine balance, and it is this balance that keeps life going. When poisonous and harmful substances enter these elements and make them unfit for use, the balance breaks down, and the result is environmental pollution. In our time pollution has grown into one of the greatest dangers facing mankind, and Bangladesh, a small country with a very large population, feels its bitter effects almost everywhere.

Air Pollution

The most common form of pollution is the pollution of air. In our cities the sky is often clouded with smoke coming from factories, brick kilns and the endless stream of buses, trucks and cars. Old engines give off thick black fumes, and the burning of rubbish adds more poison to the air. During the dry months the air of Dhaka becomes so dusty and heavy that breathing itself feels difficult. Such foul air brings coughs, asthma, headaches and diseases of the lungs and heart, and it is the young and the old who suffer most from it.

Water Pollution

Water pollution is no less alarming in our land of rivers. Mills, tanneries and industries release their untreated chemical waste straight into rivers like the Buriganga, whose water has already turned dark and lifeless. Sewage from homes, chemicals from farms and heaps of rubbish also flow into ponds and canals. Because of this, fish die, the water gives off a foul smell, and those who use it fall sick with diarrhoea, dysentery and skin diseases. In a country where people depend on rivers for fishing, farming and everyday needs, such pollution is a direct blow to daily life.

Soil Pollution

The soil that feeds us is also being damaged day by day. In order to grow more crops, farmers pour large amounts of chemical fertilisers and pesticides into their fields. These may increase the harvest for a while, but in time they destroy the natural fertility of the land and poison the crops. Plastic bags, bottles and other waste are thrown about carelessly and mix with the earth, where they lie for years without rotting. Slowly the soil loses its strength and its power to yield healthy food.

Sound Pollution

Another kind of pollution that troubles our cities is sound pollution. The constant blowing of horns, the roar of machines, the loudspeakers at rallies and functions, and the noise of construction work fill the air with an unbearable din. Such ceaseless noise disturbs sleep, weakens the nerves, and can even harm the power of hearing.

Effects

The effects of all this pollution are deep and lasting. It damages the health of millions, kills fish and wildlife, and upsets the natural rhythm of the seasons. The reckless cutting of forests, joined with the rising smoke of industry, adds to global warming. For a low-lying country like Bangladesh this is especially dangerous, for it brings irregular rainfall, floods, cyclones and the threat of a rising sea that may one day swallow our coastal lands.

Remedies

Yet the situation is not hopeless, for pollution is caused by human hands and can be checked by them too. Factories must be compelled by law to treat their waste before letting it out. Vehicles should be kept fit, and cleaner fuels used wherever possible. We should plant trees in great numbers, keep dustbins in every home and street, and refuse to use materials that harm nature. The government should frame strict laws and see that they are truly obeyed, while schools, mosques, temples and the media should work tirelessly to make people conscious of their duty toward the earth.

Conclusion

Environmental pollution is a problem that we ourselves have created, and therefore its remedy also lies within our reach. A clean, green and healthy environment is not a matter of comfort alone but a condition of our very survival. If each of us grows aware of the danger and joins hands in the great task of protecting nature, we can surely save our beloved country and pass it on, fresh and safe, to the generations that will come after us.
