Water pollution is a change in composition and quality of water that is not suitable for different uses, exceeding permissible standards and adversely affecting human life, health and creatures.

Natural water exists in many different forms: sewage, water in rivers and lakes, exists in the form of vapor in the air. Contaminated water means that its constituent exists in other substances, which can harm humans and the life of creatures in nature. Polluted water is often difficult to overcome but must be avoided from the beginning.

In the daily life, under the current growth rate, people inadvertently pollute water sources with chemicals and waste from factories and enterprises. The individual units use groundwater in the form of drilling wells , after stopping not using it, it is not sealed the holes that make dirty water run in and contaminate groundwater. The factories exhaust fumes industrial dust in the air as air pollution, when it rains , pollutants will be mixed into storm water also contributes to water pollution.Carbohydrates, proteins, fats ... are often present in domestic sewage, urban wastewater, food processing industry wastewater are easily biodegradable organic substances. In domestic water, about 60-80% of organic matter is easily biodegradable. Biodegradable organic substances often adversely affect aquatic resources, because when decomposed These substances will reduce the dissolved oxygen in the water, leading to fish and shrimp death. Many pathogenic microorganisms present in water harmful to use water in daily life . These organisms can transmit or cause disease to humans. These disease-causing organisms do not originate from water, they need a host to live, parasitize, grow and reproduce. Some of these disease organisms can live for quite a long time in water and are a potential risk of disease transmission. These organisms are bacteria, viruses, protozoa, helminths. There are also a number of agents such as colorings, flavoring agents, etc.In the world every year there are about 60,105 tons of synthetic organic substances including fuels, pigments, pesticides, growth stimulants, and additives in food and pharmaceutical products. These substances are often toxic and have a high biological durability, especially aromatic hydrocarbons causing strong environmental pollution, greatly affecting human health.The harmful bacteria in polluted water from human and animal wastes can cause cholera, skin cancer, typhoid and polio.

Hi everybody! I am a poor old woman. No, that was before, but now I have enough money for my business. Do you wonder why that is? Let me tell you:
Previously, I worked as a fan seller, but it was not very popular. Until one day, I still remember it, it was a hot summer afternoon, because the sales were too tired to stop at a certain tree. Then I met an old man resting under that tree. I lamented to him: "The fan sold too little! I must have nothing to eat this afternoon! I overslept. And naturally, when I woke up, my fan was smudged a lot. I was very angry. Because I thought it was that man, I made him pay for me, he just laughed without saying anything, making me even more angry, people came to buy a lot, I was surprised, with that amount of money. My family no longer has to live in poverty.

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.

bài thứ nhất : Talk about your family customs and traditions

Almost everyone in the house will have a traditional custom. My house also has and I think everyone's customs will be similar to mine, that is, every 30 New Year's Eve my house is cleaned. Old things will be bought new to replace. And most especially, this traditional package of banh chung, banh tet, everyone must have. As soon as the cake is wrapped, we will sit together, we even stay up until night to steam the cake. Because of wrapping the cake, we sat together again and became closer. I really like this custom.

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.
