Definition of water pollution : is the contamination of water bodies ,such as lakes, aquifers ,groundwater ,oceans ,etc .Water pollution occurs when pollutants are directly and indirectly discharged into water bodies without adequate treatment to remove harmful compounds .
Suggestion:
* Water pollution is an extreme problem on a global scale which people are having to cope with on an increasingly regular basis.
- Causes : Water is polluted by a variety of reasons. Firstly, the amount of industrial and domestic sewage results in the destruction of water resources. There are many manufactures are constructed along rivers or seas so that their wastes are being dumped directly to our water. Secondly, a lack of filtering system also a main cause of this issue. Because of an expensive purifying infrastructure system, most factories avoid building one.
- Solutions : However, water pollution can be solved by two possible solutions. Governments have a strong responsible to raise the awareness of public about protecting the water environment. Mass media could be used as a method to educate people about how water is important to our society. In addition, factories need to be encouraged to build the filtering system. They could ask for supporting investment from governments or some environmental organizations to create their own effective one.
* In conclusion, water resources are at risk because of sewage come from both industries and domestic and also a lack of purifying system. However, the attitude of citizens and producers could reduce the serious of the problem.

Water pollution is a source of water contaminated with chemicals or foreign substances that are detrimental to human, plant or animal health. Almost all types of water pollution are harmful to the health of humans, animals and plants. While it may not cause immediate harm to our health, it may be harmful after long term exposure. In addition, water pollution can harm economies as it can be costly to treat and prevent pollution. The cause comes from water environmental pollutants including: fertilizers and pesticides from agricultural production; wastewater and waste from food processing; lead, mercury and other heavy metals; Chemical waste from industries. To limit the consequences that environmental pollution causes. More than anyone else, each citizen must be self-aware of his or her own work. The State and management agencies must constantly propagate to raise people's awareness. Strictly inspect and handle factories and enterprises that violate environmental regulations, tighten the ban on indiscriminate littering anywhere. It is necessary to have effective methods and means of waste treatment, to avoid the problem of stagnant garbage and pile up polluting piles. Use public transport or ride bicycles or tram to replace the vehicles that pollute the streets. Promote the planting of many green trees to create freshness and harmonize the living environment. In addition, scientific researchers or each person need to research and invent the equipment and tools to treat, recycle or sort waste to reduce effort and cost, while minimizing the amount of waste each day. Protecting the environment is a responsibility and happiness not only for anyone, let's act together for a green - clean - beautiful and safe living world. Our mission is to create a healthy and safe living environment.

Currently, the issue of environmental pollution is a hot topic in the newspapers and receives a lot of attention from the people. In particular, the problem of water pollution in Vietnam has been becoming more and more serious. Through the media, we can easily see images, as well as articles reflecting the current environmental situation. Although departments and unions make efforts to call for environmental protection, water resources protection, ... but it seems that it is not enough to improve the situation of increasing pollution. The status of planning for urban areas has not been linked to the problem of waste treatment, wastewater treatment ... so there are still outstanding in big cities, industrial zones, urban areas, ... Environmental contamination is at an alarming rate. Many people believe that the things they do are too small, not enough to harm the environment. Some people think that protecting the environment is the responsibility of the state, at all levels of the government ... while others think that whatever the environment is polluted, it will "not lose money". , and environmental pollution does not affect me much. And these thoughts will significantly affect the education as well as thinking about environmental protection of the younger generations. In short, although the environmental pollution in Vietnam is serious, it can still be saved if each citizen knows how to contribute, join hands to protect the environment. Let's shout out the slogan "For a green - clean - beautiful environment" and also for our own life as well as for generations to come.

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 plastic 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.

Ô nhiễm môi trường đã và đang trở thành vấn đề gây tranh cãi và nó đã gây ra nhiều khó khăn áp lực lên cuộc sống của chúng ta. Tình trạng ô nhiễm môi trường trên trái đất đã chạm đến mức báo động vì vậy hiện tại những giải pháp cấp thiết từ chính phủ cũng như sự hợp tác của mỗi cá nhân là vô cùng quan trọng. Điều đầu tiên nói đến, những hoạt động công nghiệp được coi là nguyên nhân chính cho việc ô nhiễm không khí. Cùng với sự nóng lên toàn cầu, sự đốt cháy những nhiên liệu hoá thạch, các phương tiện xe cộ và các nhà máy đang làm ô nhiễm không khí bằng sự thải ra những khí độc hại. Điều thứ hai, sự phá rừng bừa bãi cho việc sử dụng đất, lạm dụng phân bón và sự thải ra những chất gây ô nhiễm như túi bóng hoặc những túi không thể phân hủy xuống đất đã ảnh hưởng nhiều đến hệ sinh thái và dẫn đến sự ô nhiễm đất. Điều này đã để lại những ảnh hưởng tiêu cực lâu dài lên hệ thực vật và sự phì nhiêu của đất. Những giải pháp cấp thiết để làm giảm tác hại của ô nhiễm môi trường và giữ gìn môi trường cần được đưa ra sớm nhất có thể. Chính phủ có thể quản lí quá trình xử lí các chất độc hại của các nhà máy lớn vì vậy họ có thể ngăn chặn những chất ô nhiễm ra ngoài môi trường. Hơn nữa, những quy định và luật lệ nghiêm khắc hơn đối với sự khai thác rừng có thể giúp bảo tồn môi trường tự nhiên. Các cá nhân cũng cần phải có trách nhiệm và nâng cao ý thức về việc bảo vệ môi trường. Kết lại, ô nhiễm môi trường đang nhanh chóng trở thành một mối nguy hiểm với toàn cầu, ảnh hưởng trực tiếp tới cuộc sống của chúng ta, và vì lợi ích của môi trường cũng như của công dân trên toàn thế giới, chúng ta cần chung tay bảo vệ ngôi nhà chung của chúng ta- Trái Đất.

- Definition: Thermal pollution means a change in the water temperature.

- Causes:

+ Power station are one factor. They use water in the nearby lakes or rivers to cool their equipment, which heats up the water. Then they dump the hot water back into its source.

+ Thermal pollution may also happen due to the discharge of cold water from reservoirs into warm rivers.

- Effects: Most aquatic creatures need a certain temperature to survive. Warmer water has less oxygen in it, and this can harm fish populations. Besides, warmer water can cause harmful algal blooms. This can change the colour of the water like in the first picture and, more seriously, the algea poisons the fish. - Solution: In many places, they build cooling towers like in the second picture to cool down the water from power stations.

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 dramatic 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.

In recent years, the mass media have been reporting so much on environmental issues, attracting a great deal of attention from the public. In Vietnam, the most recently representative event is the mass death of fish from Ha Tinh province to Quang Tri province, causing huge damage to the government till hundreds of billion Dong, affecting the lives of inhabitants here. Not only Vietnam, some other countries in the region and in the world also suffer from severe environmental pollution. For example, in Beijing, China, the amount of air pollution is in excess of the permitted level, most of people here have to live with respiratory diseases. To overcome this current issue, the governments of many governments have the different measures to minimize the amount of pollution emitted to the environment. Many activities have been encouraged such as recycling, reusing, reforestation, waste collection, using alternative energy and so on. There have been a number of global campaigns to raise awareness of citizens like the Earth Hour with slogans, posters such as 'Protect our Earth', 'Green Environment', etc. In Vietnam, the government has also passed many laws fining heavily the organizations and individuals. Step by step, we are trying our best to protect the environment, turning the Earth into a wonderful place to live. Hope that in the future, the environmental pollution will no longer be a concern.

Những năm gần đây, các phương tiện truyền thông đại chúng rầm rộ đưa tin về các vấn đề ô nhiễm môi trường, thu hút sự quan tâm lớn của cộng đồng. Ở Việt Nam, sự kiện tiêu biểu gần đây nhất là vụ cá chết hàng loạt từ cá tỉnh Hà Tĩnh cho đến Quảng Trị, làm thiệt hại của nhà nước hàng trăm tỉ đồng, ảnh hưởng đến đời sống sinh hoạt của người dân nơi đây. Không chỉ Việt Nam, một số nước khác trong khu vực và trên thế giới cũng chịu ảnh hưởng của ô nhiễm môi trường một cách nghiêm trọng. Ví dụ như ở Bắc Kinh, Trung Quốc, lượng ô nhiễm trong không khí đã vượt quá mức cho phép, đa số người dân phải sống chung với các bệnh liên quan đến hô hấp. Để khắc phục thực trạng này, chính phủ của các nước đã có những biện pháp khác nhau để giảm đến mức tối đa lượng ô nhiễm thải ra môi trường. Nhiều hoạt động được khuyến khích như tái chế, tái sử dụng, tái trồng rừng, thu gom rác thải, sử dụng năng lượng thay thế,...Đã có rất nhiều những chiến dịch mang tính chất toàn cầu nhằm nâng cao nhận thức của công dân như sự kiện Giờ Trái Đất với các tấm khẩu hiệu, áp phích như ‘Bảo vệ Trái Đất’, ‘Môi trường xanh’,... Ở Việt Nam, chính phủ cũng thông qua nhiều chế tài xử phạt nặng các doanh nghiệp, cá nhân có hành động phá hoại môi trường như săn bắn bất hợp pháp, vứt rác bừa bãi, phá rừng... Từng bước, chúng ta đang cố gắng hết sức bảo vệ môi trường trong lành, biến Trái đất thành một nơi tuyệt vời để sống. Hi vọng rằng trong tương lai gần, ô nhiễm môi trường sẽ không còn là vấn đề đáng lo ngại nữa.

Topic: ENVIRONMENTThe environment is everything in the world, everything around us. There are four kinds of environment: water, air, soil and creature. The environtment is very important for our life, our health and our future. If you want to have a good health, you must live in a good environment. Countryside is the best example because there aren’t many factories and there are many trees in the countryside so the air is very fresh. It makes you feel comfortable and healthy.But today, the environment is the ho'est problem in the world because it is polluted by people who live in it- the main reason which causes the environmental pollu)on. The water becomes dirty and becovered by trash. The factories decant chemistry into stream, river and sea. Fishes, sea plants are died and +oat on the water surface. Many trees in the forest are cut down to make furnitures. Peoplethrow trash onto the water, the street or in the park. In addi)on, the weather is very hot and don’t have any rain in the long )me. There are many other reasons which make environmental pollu)on.Environmental pollu)on is not good for your healthy. It is the cause which makes illness and cancer like respiratory disease, lung cancer,etc… and you may die soon. So people have to do everything that is possible to reduce the pollu)on, protect the environment. Reusing, reducing and recycling arethe best ways.• When you buy some food in the market, the sellers usually give you plas)c bags to put the food in. Then, when you come home, you take the food out and throw the plas)c bags away. You know, the plas)c bags are di2cult to be burned. So now, please don’t do that, you can wash and use them for the next )me. It’s reusing.• Trees are very useful. They give us the oxygen and make the air clean. But everyyear, many trees are cut down illegally. We should avoid this situa)on. Reducing your family’s domes)c waste is a good idea and I think it’s necessary to do that. Because the waste is very dirty and solving waste is always the ho'est problem that always need the solu)ons.• The last, you can recycle the paper, cans, )ns,ect… which are used. By doing that, you can ear money and protect the environment.The environment is important for our life so we have to protect it. We should solve the environmental pollu)on together. Protect the environment, protect our life.
