Environmental pollution has become a controversial issue that puts severe pressure on our rhythm of life. The pollution on Earth has reached such an alarming level that immediate involvement from governments and individuals collaboration now are of great importance. First and foremost, industrial activities are considered to be the main cause for air pollution. Along with the global industrialization, the burning of fossil fuels, motor vehicles and factories are contaminating the air by their emission of harmful fumes. In the second place, pervasive deforestation for land use, overuse of fertilizers and the dumping pollutants such as plas or non- biodegradable packing in the ground has affected the ecosystem and led to soil pollution. This puts bad long- term effects on vegetation and soil fertility. Serious attempt to relieve the effects of pollution and preserve the environment need to be made as soon as possible. Governments can monitor the exhaust purification process of large factories so that they can prevent dangerous exhaust from the environment. Moreover, stricter regulations and laws against forests exploitation can help preserve pristine environment. Individuals should be responsible and raise awareness for the protection of environment. In conclusion, pollution has increasingly become a threat to the globe, directly affects our life and for the sake of environment and all citizens around the world, we should work hand in hand to protect our friendly house- the earth.
Water pollution is the contamination of bodies of water such as lakes, rivers, oceans, and groundwater. Water pollution can have many different cause.The main reason for water pollution is the daily activities of everyone.The next reason, disasters always happen contaminate the water. Besides, the operation of the plant also pollutes the water. because industrial waste water has not been treated, it pollutes the water. Water pollution brings a lot of bad effects to people. Firstly, it seriously affects human health. Secondly, it affects water sources and aquatic organisms because water is the habitat of fish, crabs, shrimp. The most important measure is to raise the sense of responsibility of the community.In addition, we must save water; treatment of waste before being discharged into the environment.
There are many types of environment pollution in the world, air pollution is one of them. The main cause of air pollution is the smoke and dust released from factories. They are very toxic to us humans. And they are also very bad for the environment. In addition, air pollution is also generated from the exhaust fumes of motor vehicles such as motorcycles and cars. As a result, the air source in the flock is heavily polluted, causing a greenhouse effect, causing the Earth to heat up. The ice from the North and South poles is being melted due to rising sea levels, causing flooding. We need a way to fix them immediately, otherwise the consequences will be even more dangerous.

Water pollution is the dumping of foreign materials in water. Water pollution has the following advantages: helps in disposing harmful materials off the land surface and is inexpensive. Disadvantages of water pollution include: waterborne diseases, death of aquatic life and hindrance to boating activities.Pollution is the introduction of contamination materials into the natural environment that causes adverse changes. There are many forms of pollution, including water pollution, soil pollution and air pollution. All types of pollution are known for their many harmful effects. However, water pollution helps in avoiding other forms of pollution. Dumping of waste in water helps to free the land of harmful materials. When chemicals from factories are dumped in water rather than on land, it means crops from rain-fed agriculture will not be affected. Water pollution prevents health hazards. When materials are dumped in rivers, they become unavailable to human beings and hence cannot affect them, for instance, poisonous food materials.Water pollution increases nutrient loading, leading to eutrophication. Organic wastes such as sewage and farm waste put high oxygen demand on the receiving water body resulting in oxygen depletion with drastic impacts on the entire ecosystem. A variety of pollutants discharged from industries, which include heavy metals, solids, organic toxins, nutrients and oils, reduce oxygen availability. Crops irrigated with water contaminated with heavy metals pose a health risk to humans.

Nowadays, environmental pollution is a hot issue, causing huge waves in public. There are a lot of scientific studies on this issue. Do you know that the cause of pollution originates from the tasks seeming small in our daily lives such as littering, deforestation, or the direct discharge of smoke from vehicles, factory into the environment without treatment. However, if these actions are repeated many times, gradually, the amount of pollution is increasing and has the opposite impact on our lives. The manifestation of environmental pollution is an increase in the carbon footprint in the air, soil and water, which is a gas that does not sustain life. Environmental pollution is also a direct cause of global warming, leading to a series of phenomena, such as the greenhouse effect, ice caps melting, natural disasters such as droughts, floods, volcanic eruption and so on. The sea level is rising, more and more natural disasters occur, which threaten all species, make some of which be rare or extinct, break the ecological balance on the Earth. Human beings are not exception. We are breathing polluted air, eating unsafe food. In recent years, we have seen a drama increase in the number of people suffering from respiratory and digestive diseases. In conclusion, environmental pollution is a matter taking a lot of concern. It is time for us to take action to overcome this current issue, to protect our own lives.

Ngày nay, ô nhiễm môi trường là một chủ đề nóng hổi, gây lên làn sóng trong dư luận. Đã có rất nhiều công trình nghiên cứu khoa học về vấn đề này. Bạn biết không, nguyên nhân của ô nhiễm bắt nguồn từ những công việc tưởng chừng như rất nhỏ trong cuộc sống hàng ngày của chúng ta như xả rác bừa bãi, phá rừng làm rẫy, hay tù khói của xe cộ, các xí nghiệp thải trực tiếp qua môi trường mà không được xử lí. Tuy nhiên nếu những hành động này được lặp đi lặp lại nhiều lần, dần dần, lượng ô nhiễm ngày càng nhiều và tác động ngược lại đến với cuộc sống của chúng ta. Biểu hiện của ô nhiễm môi trường chính là sự tăng lên vè nồng độ carbon trong không khí, đất và nước, đây là chất khí không duy trì sự sống. Ô nhiễm môi trường còn là nguyên nhân trực tiếp dẫn đến sự nóng lên toàn cầu, dẫn đến hàng loạt hiện tượng như hiệu ứng nhà kính, băng tan hai cực, các thảm họa tự nhiên như hạn hán, lũ lụt, phun trào núi lửa,... Mực nước biển ngày càng dâng cao, ngày càng nhiều các thảm họa tự nhiên xuất hiện đã đe dọa đến tất cả các loài sinh vật, khiến một số loài trở nên khan hiếm hay thậm chí là tiệt chủng, gây ra sự mất cân bằng sinh thái trên trái đất. Con người cũng không ngoại lệ. Chúng ta đang hít phải không khí ô nhiễm, ăn những thực phẩm chưa đảm bảo chất lượng. Những năm gần đây, chúng ta chứng kiến con số tăng lên đáng kể những người mắc phải các căn bệnh liên quan đến hệ hô hấp, tiêu hóa. Nói tóm lại, ô nhiễm môi trường đang là vấn đề đáng lo ngại. Đã đến lúc chúng ta phải bắt tay hành động khắc phục hiện trạng này, bảo vệ cuộc sống của chính chúng ta.

2.Causes and consequences of water pollution
The pollution of water is an important problem today. Today, throughout moutain to city, almost rivers are not pure. They are dark, black, and foul and make the bad trouble with our lives. We need fresh air, we need fresh water. We need water to drink, to bath, to clean and wash. We very need water. Land Dad, and water Mom. Water smooth, transparent, clear, and it has 70% of all our body. We can not don't need water. Water help tree grow. Water can refresh and clear all things. But today, we only have water from water city company. The water we drink, is not fresh. And it must fire to hot as 100 degree. And then, we make it cool, so we can drink. In once upon a time, all rivers are fresh. And we can swim in that, it's very funny. In that rivers, we have fishes, too, and shrimp, and very much see animals. But now, with our rivers, there have no fish, or shrimp. Because there're too dirty. If we want to make our rivers revival, we need learn the way to not pour the pollution things to our rivers. It's very difficult, I know. But if we truely want our rivers have the blue, not black, or grown color, we need do all things from the begin. Nowadays, we have many polluted company, we always try to make pure water. And to have pure water, we must pay money. It's not cheap. And the last thing I want to talk with you, that we need to learn the way to not pour the dirty things to rivers. And we need save our water.
Soil pollution has now become much more of a boiling issue to all countries in the world. Due to the appearance of many fertilizers and peside, farmers have been overusing them to contaminate the soil. This poses a great health threat as peole cultivate food on the land. Additionally, industrialization does not only lead to air pollution but also contribute greatly to the severeness of soil contamination. As more and more firms dump their untreated sewage right into rivers and the sea, the aqua environment become extremely hazardous for marine animals to survive. Moreover, the fresh water for daily activities will also be negatively affected. In order to improve the situation, several methods have been implemented by governments. However, I believe the most effective way to reduce soil pollution is raising people's awareness of the issue.

Noise pollution is a noise in the environment that exceeds certain thresholds that cause discomfort to humans or animals. In most countries, noise sources are mainly from outdoor noise such as traffic, transportation, motor vehicles, aircraft and trains. school.
Unfavorable urban planning can generate noise pollution, as industrial and residential buildings can lead to noise pollution in residential areas. Records related to urban noise have been mentioned since ancient Rome
Outdoor noise can be caused by the operation of machinery, construction or musical performances, especially in some workplaces. Deafness can be caused outside (eg train) or inside (eg music).
High levels of noise can contribute to cardiovascular disease in people, such as coronary artery disease. In some animals, excessive noise can increase the risk of death by altering the carnivore, hindering the detection of prey, difficulty in reproduction, and possibly permanent hearing loss. telecommunications.
Noise can make resting almost impossible. This kind of noise is often called noise pollution. It is also called "community noise." It is noise that damages the balance of normal life for people and animals.
Most noise pollution is caused by transportation. Cars, trucks, trains, and airplanes can all be very loud. And in many cities around the world, people's homes are very close to these transportation systems. But even things like building tools and music can be noise pollution. Sometimes it can be difficult to find a quiet place.
Noise pollution is particularly a problem in developing countries. Growing cities and towns are not planned to reduce noise. Many homes and businesses are built next to busy roads. Traffic grows and with it the noise grows.
George Prochnik wrote a book about silence and noise in our world and culture. He said that noise can do more than just take our attention. Noise may harm our health. He says that noise can greatly affect our bodies. Most people know that loud noise can damage our ears. But noise can damage more than our ears. When a person experiences high levels of noise, his heart beats faster. His blood pressure gets higher. Noise can even change the balance of chemicals in a person's body.
Noise can also affect the way a person sleeps at night. A good night of sleep happens when a person is asleep for a long period of time. This is often called "deep sleep." But when there is too much noise at night, a person cannot get this deep sleep. Studies show that lack of sleep is connected to many different health problems. If a person is always tired, her body is not as strong. She is not able to fight sickness easily. She may also have a difficult time concentrating on work during the day.
Researchers in New York City studied the effects of noise on a school. The school was near noisy train tracks. Some of the rooms of the school faced the train tracks. Other rooms were far from the train. They were quieter. The researchers tested children over six years. The children on the noisy side of the school were not as good at reading as the children on the quiet side of the school. The school then built special walls near the tracks to make it quieter. After this, reading improved.
But noise does not just affect humans. Birds sing songs to communicate. But if it is too noisy, the birds cannot communicate. Cows feed less and produce less milk when it is noisy. Some studies even show that the growth of some plants can be affected by noise.
Louis Hagler is a doctor in California. He fights for quiet in cities. He believes that cities should treat noise like any other dangerous thing.
"We do not say to people 'you just have to learn to live with waste in your water.' Why should we have to live with waste in our ears?"
But for many people, the problem of noise is not about health. It is about peace. In many religions, quiet is connected to peace. People use times of quiet to communicate with God. They pray or read holy books. Noise can keep us from thinking about God. It may even be difficult to pray if too much noise surrounds us.
In some religions, holy men and women have special times of silence. Some of these people make a promise not to speak for a period of time. This can be very difficult. But these men and women see their silence as a way to control themselves and honor God.
These men and women use silence as a way to show respect. But this does not only happen in churches. All around the world people make their voices quiet to respect others. People are quiet in cemeteries, where people bury the dead. They are quiet in museums where people learn about art or history, and in libraries where people read books. People also use silence as a way to honor people who have died. Often, at special events orcelebrations, people will have a moment of silence. This is a short time when large groups of people quiet their voices to remember the dead. Quiet and silence is special. It is important.
But finding quiet places in a busy world can be difficult. Noise is all around, and sometimes you can not avoid it. But you can reduce noise in your life. The website Green Living Tips discusses the problem of noise on their blog. Here are some things they say to reduce noise in your life.
Keep your mobile telephone at a low volume.
If you have to raise your voice when you are talking to someone, something is wrong. Look for what is creating noise around you and what you can do to control it.
Train your pet dogs to not bark without reason.
Make an effort to reduce noise at night time when people are sleeping.
If you want to share your music with people who live near you, do not do it by playing music louder. Play music at a level that only you can hear, or only indoors.
If you live a life that creates a lot of noise, plant tall plants around your home. These plants will block some of the noise that you create.
Instead of driving a car or riding a motor bike, ride a bicycle instead. This will reduce noise on the roads. And finally, if you have children, take them to quiet areas and let them listen. Teach them to value quiet in their lives.
Escaping from the noise of life can give us energy. It can make a person calm. It can help bring balance to the body. Quiet can bring us closer to God and help us rest.
