Noise pollution is one of the popular types of pollution nowadays. The definition of noise disturbance is the disturbing or excessive noise that may harm the activity or balance of human or animal life. Noise pollution is the result of the noise of machine and transportation systems, motor vehicles, aircrafts, and trains. Although noise contamination doesn't cause some serious effects like air pollution, water pollution, or soil pollution, it also had bad impact on human life. In a high level, noise disturbance can contribute to cardiovascular effects in human and an increased incidence of coronary artery disease. In animals, noise can increase the risk of death by altering predator or prey detection and avoidance, interfere with reproduction and navigation, and contribute to permanent hearing loss.

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.

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.

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.

Life is a process, not a goal. Choosing where to spend your time, to spend your life has always been something to wonder by many. Countryside in general is a great place to live, however, also there are some disadvantages living there compared to in the city as well.

On one hand, the living environment in the countryside is fresh, clean and friendly in most cases. You don't have to worry about the industrial air, dust or pollution of the million vehicles commuting all day and all night. One more plus thing is that you are surrounded by green trees. There are spaces for you to farm, to enjoy planting and raising animals. It is most suitable for nature lovers.

On the other hand, there are high chances that it will be difficult to find certain forms of convenience like shops, airports, traffics, hospitals, entertainments, ... The choices of schools for your kids will also be limited. Travelling might be an ordeal sometimes since the public transports will not be very convenient as living in the city.

One more thing to consider is the people. In general, people in the countryside are more friendly and willing to give a hand. In the city however, everyone is busy going about their life, you are more likely to find yourself lonely in a crowded city than a lovely little town in the countryside. 

Whichever kind of place you choose to live, it should be suitable for your life style, your family and most of all, your long-term plan of living. As long as you're happy, it does not matter the city or the countryside after all.

- 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.

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.
