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.

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.

Các em học sinh có thể tham khảo bài văn mẫu về vấn đề ô nhiễm môi trường nhé. Bài viết chỉ mang tính tham khảo.
Đề bài: Viết một bài văn ngắn (khoảng 400 từ) trình bày suy nghĩ của anh / chị về vấn đề ô nhiễm môi trường ở nước ta hiện nay.
Vấn đề môi trường sống của con người trên trái đất đã và đang bị ô nhiễm là một vấn đề cấp bách đối với bất kì quốc gia nào. Vì nó gây ra những hiện tượng biến đổi khí hậu dẫn đến những thảm hoạ thiên tai khủng khiếp. Ở Việt Nam sự ô nhiễm môi trường là vẫn đề đáng báo động. Đây là một hiện tượng xấu, nhiều tác hại, cần nhanh chóng khắc phục.
Trước hết, ta cần hiểu môi trường là gì? Môi trường sống của con người là một khái niệm rộng. Nó bao gồm tất cả các yếu tố tự nhiên và vật chất nhân tạo bao quanh con người, có ảnh hưởng đến cuộc sống, sản xuất, sự tồn tại, phát triển của con người và mọi sinh vật trên trái đất. Môi trường có hai loại chính: đó là môi trường tự nhiên và môi trường xã hội. Môi trường tự nhiên bao gồm các thành phần tự nhiên như địa hình, địa chất, đất trồng, khí hậu, nước, sinh vật,… Môi trường xã hội là tổng thể các mối quan hệ giữa con người với con người, quan hệ cá nhân với cộng đồng thể hiện bằng luật pháp, thể chế, cam kết, quy định,…
Thực trạng ô nhiễm môi trường đang diễn ra rất nghiêm trọng.Ô nhiễm nguồn không khí: các nhà máy đã và đang thải ra môi trường không khí một nguồn cacbonnic khổng lồ, các loại axit, các loại khí gây hiệu ứng nhà kính, khói bụi xe hơi và các loại động cơ khác. Ô nhiễm nguồn nước: hiện nay thế giới và đặc biệt là Việt Nam đã bị ô nhiễm nguồn nước, nhu cầu về nước uống và nước sinh hoạt ở nhiều vùng miền đang bị thiếu nghiêm trọng, số lượng người được sử dụng nước sạch chiếm tỉ lệ không lớn. Các nguồn nước: ao, hồ, sông, suối, biển cả đại dương, nguồn nước ngầm, nước mưa,… Ô nhiễm nguồn đất: đất đai ngày càng bị thoái hoá, bị rửa trôi, rác thải công nghiệp, rác thải sinh hoạt, rác thải bệnh viện

Ô nhiễm môi trường gây ra nhiều tác hại nghiêm trọng nên cần có những biện pháp để ngăn chặn. Bản thân con người phải ý thức được những tác hại to lớn khi môi trường ô nhiễm. Hệ thống pháp lí, chế tài nghiêm minh để xử phạt thích đáng cho các cá nhân và tổ chức vi phạm. Nhà trường phối hợp với các ban ngành thường xuyên nhắc nhở, tuyên truyền, kiểm tra ý thức tự giác của mọi người về việc giữ gìn vệ sinh. Nên có những hình thức khiển trách đúng mức đối với những học sinh có thói quen vứt rác bừa bãi. Giáo dục ý thức cộng đồng về bảo vệ môi trường. Trong thời gian gần đây, chúng ta thường được nghe nói đến phong trào “Giờ Trái Đất” .Đó cũng là một trong những hoạt động thiết thực để góp phần bảo vệ môi trường. Và chúng ta cần phải thực hiện các giải pháp trên một cách đồng bộ, thường xuyên để khắc phục những hậu quả của sự ô nhiễm môi trường, tạo ra môi trường sống trong lành cho con người,
Tóm lại, ô nhiễm môi trường ở nước ta hiện nay là một vấn nạn gây hậu quả nghiêm trọng cần lên án và loại bỏ. Hãy bảo vệ môi trường. Bảo vệ môi trường là bảo vệ sự sống của mọi người, vì vậy mỗi người chúng ta cần có ý thức, góp phần chung tay xây dựng một môi trường xanh – sạch – đẹp.

Today, the problem of environmental pollution has become more and more serious in Vietnam. On the mass media every day, we can easily see images, information about the environment is polluted. Despite the calls for environmental protection, pollution has become increasingly severe. This makes me think ...

{Expression}
The environment is calling for help!
From the beginning of the year, there have been many new statistics on the state of the environment in Vietnam. And sadly, these are disappointing numbers ...

{Common Number}
According to a global environmental review by the United Nations Environment Program (UNEP) Hanoi and HCMC. HCM is in the list of 6 most serious air pollution in the world. Concerning dust concentrations, the two largest cities in Vietnam are behind Beijing, Shanghai, New Delhi and Dhaka. This potential threat will undoubtedly hamper the further development of these cities. According to a study on stable environmental indicators conducted by Yale University, Vietnam ranks the lowest among eight Southeast Asian countries.

{-Water pollution}
The status of planning urban areas is not associated with the problem of waste treatment, so the environmental pollution in big cities, industrial parks, urban areas are at an alarming level. Of the total 183 industrial parks in the country, over 60% of industrial zones have no centralized waste water treatment system. In urban areas, only about 60% - 70% of solid wastes are collected, wastewater and wastewater treatment facilities and wastes so as not to meet the requirements of environmental protection. Unprocessed waste is discharged directly into rivers and lakes and it is forecasted that by 2010 it will be 510,000m3 / day. A sad example of the discharge of waste water, no one would know, is the case of the Thi Vai River being contaminated by the chemicals discharged from Vedan's sweet corn factory for 14 years. This causes the river to be severely polluted affecting the lives of many people around. Another example is the pollution of Hoan Kiem Lake, a symbol of national culture.

{Air pollution environment}
{Earth environment contaminated}
Not only the water environment but the air environment and soil environment is also seriously polluted. The air quality in most urban areas in Vietnam exceeds the permissible standard. In Ho Chi Minh City, measurements at six air monitoring stations show that 89% of air sampling fails. The high level of health hazards, in which the suspended dust is the leading pollutant in the area. In addition, the air pollution due to lead also increased rapidly, specifically the concentration of lead measured in early 2009 to now fluctuate at the threshold of 0.22 - 0.38g / m³, too standard allowed about 1.5 times. On the land environment, the results of several surveys show that heavy metal content in land near industrial parks has increased in recent years. As in the Phuoc Long industrial cluster (Binh Phuoc) Cr content is 15 times higher than standard, Cd is 1.5 to 5 times higher, As is 1.3 times higher than standard. (Cr, Cd, As: toxic chemicals) Pesticides also affect the soil. Although the volume of pesticides used in Vietnam is low, on average from 0.5 to 1.0 kg / ha / year, however, in many places have detected pesticide residues in the soil.

{Reason}
What is the cause of these events?

{Lack of awareness of people}
First of all, it is the lack of serious awareness among many people, especially young people. Many people think that what they do is too small, not enough to harm the environment. Others argue that environmental protection is the responsibility of the government, not of the government. Others think that environmental pollution has nothing to do with anything, and environmental pollution does not affect me much ... Seeing that but not so! Destruction of the environment of a person, although only a small impact, but the gathering of many people is great. The responsibility to protect the environment, though, is partly from the state, but most of it is from the people. And what we do for the environment, although we do not see it now, will in the long run affect us more or less.

{- Some for-profit businesses are defying the consequences}
{The management of the state is not tight}
Another cause of environmental pollution is the lack of responsibility of businesses. Due to the target of maximizing profits, many enterprises have violated mining procedures, contributing significantly to environmental pollution. In addition, the lack of strict control over the state's environmental protection has also helped to destroy the environment. Vietnam lacks strict environmental protection policies and regulations and is strongly attracting investment capital

Worldwide, soil pollution caused by the presence of xenobiotic chemicals (the human) or due to changes in the natural soil environment. It is characterized caused by industrial activities, agricultural chemicals, or due to improper waste disposal places. The common chemicals including oil hydrocarbons, aromatic hydrocarbons more rings (naphthalene and benzo as (a) pyrene), solvents, pesticides, lead, and other heavy metals. Pollution levels correlated with the degree of intensity of industrialization and the use of chemicals.

The concern over soil contamination stems primarily from health risks, the direct contact with contaminated soil, vapor from the pollutants, secondary pollutants from ground water supplies .[first] Mapping and cleaning up contaminated lands are often time consuming and expensive, requiring extensive knowledge of geology, hydrology, chemistry, computer modeling skills, and GIS in environmental pollution as well as the appreciation of the history of the chemical industry.

In North America and Western Europe with soil pollution levels are known to most, many countries in this region have a legal framework for identifying and solving environmental problems. The developing countries have less stringent regulations, although some countries have gone through industrialization.

My class plans to go to the beach to play this summer. I’m the class representative so I’ll be the one to plan this outing. We plan to go two days a night. The first day we will rent a car to go to Ha Long Bay. We will go in the morning. I choose a mid-range hotel for the right price. On the first day we will experience the games here. In order to have a panoramic view of this place, we will take the cable car. When it gets dark we go to the beach and prepare for the evening barbecue. It would be great to roast meat with friends on the sand and watch the starry sky. We will eat barbecue together and sing songs. Then we will return to the hotel together to sleep and prepare for the second day. The second day we will get up early to watch the sunrise and have breakfast. Then we will visit the seafood markets to choose to buy seafood for ourselves and as gifts for relatives. After everyone has bought the necessary items, we will go take pictures and prepare the items to return home. I hope this trip will leave many memorable memories for me and my friends.

Nowadays almost everyone in the world have had a contact with computers. A great part of them has been using international computer’s net known as Internet.

I think using internet has more advantages then disadvantages. First of all, Internet provides access to a lot of information. Some of them are very useful in your job other helps in your hobby. Searching the net with Google, you can find everything you want. You can also do shopping using Internet. Of course it has no sense to buying a roll, but if you need something inaccessible, you will be able to buy it in Internet shop. You need only to select what you want, fill in some forms and click ok. In a few days you will get what you have ordered directly to your home, without going anywhere. You can pay with your credit card, pay postman when you get the package, or transfer money from your bank account. Nowadays almost every bigger bank offers transferring money with Internet. It is more faster then going to the bank and filling blankets. Transferring money in traditional way takes about a day, using Internet you can do this in few seconds even in Saturday and Sunday evenings. What’s more internet banks give you insurance against unauthorized transaction. Some people thinks that their money can by easily stolen by hackers. It isn’t true because the easiest way to steal your money from internet bank is breaking to your house and stealing you card of codes. Internet banks have very good protections witch make them practically unbreakable.

Next advantage of internet is email. Internet mails get in a few seconds in their destinations. It is very important when you want to send something for example to Australia. Of course you can send not only texts. You can email whatever you want, movies, photos, songs, computer programs etc. Costs are very important advantage of emails. Sending an email is much cheaper then phoning, or sending normal letters.

Beside a lot of advantages, Internet has some disadvantages too. First of disadvantages is that people who spend too much time sitting in the front of computer can easily gets ill. Radiation emitted by computer’s screen is harmful to eyes. People who spend too much time at their homes (because they needn’t go anywhere, they can do everything using Internet) are getting weaker. Sitting a for long time is also harmful to the spine.

Second disadvantage is that Internet can by addictive. Some people just can’t live without it. They have no real friends and when Internet is down they are getting furious.

Internet has some opponents but more and more people treats Internet like telephone, or radio. They use it for fun and work, and I think at present living without internet would be quite difficult.

In this paper, I would like to discuss about the advantages and disadvantages of the internet. In the first place, the internet benefits us in many ways. It provides us with much information from every corner of the world. It helps us to know about what is happening on the earth and updates us with the most recent news. Also, the internet helps us to widen our social network with many friend in every country in the world. Through some programs such as Skype, facebook, Yahoo Messenger, etc, we have chance to make friend and talk to a variety of people. Moreover, it entertains us. Sometimes we can spend times listening to music or watching films on some websites. However, the internet also causes us many problems. The first one is to our health. Some people spend too much time searching and playing on the internet, which is not good for their brains and eyes. Next, it also prevents us from some activities such as reading books or going our with our friends. In addition, some programmes on the internet contain some bad content such as violence or ***** which are not good for young people's mental lifem.

The development of tourism has led to a possibility that space travel will be widely available in the future. However, I would contend that this form of travel is the negative development for the following reasons.
To begin with, there are many negative aspects of space travel. Firstly, the equipment required for this means of travel is relatively expensive because money needed to produce aircrafts is far more than the amount for other vehicles. Secondly, space tourism causes environmental contamination. When operating, aircrafts release huge amount of exhaust fumes into the surroundings, and the ozone layer will be seriously affected while the rockets are launched. Finally, travellers would face the risk of problems related to health. Visiting a strange star is a potential danger because there are circumstances that we cannot control or give first aid whenever necessary.
Some people may claim that space travel can broaden our knowledge of the universe. However, I believe that planets where no life exists have nothing to visit, except for stones and rough surfaces. In lieu of taking the tour, people can have many other ways to gain knowledge of the planets and the universe by reading science books and watching science movies to be safer and less costly. The purposes of travelling base largely on relaxation and discovery; therefore, no justification would be rational to justify the growth of space tourism. That is the reason why many people reject the development of space travel.
In conclusion, I firmly hold the view that space tourism has many drawbacks than benefits, and the development of this industry should not be promoted.
