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.
Nowadays, one of the biggest problems human are facing with is water pollution. Water pollution is defined as the presence in groundwater of toxic chemicals and biological agents that exceed what is naturally found in the water and may pose a threat to human health and/or the environment. A lot of causes are responsible for this issue. And they lead to extremely bad consequences. I’d like to explain more in the following paragraphs.
Some typical causes of water pollution are Industrial waste, Sewage and waste water, Mining activities, Accidental Oil leakage, Burning of fossil fuels, Chemical fertilizers and pesticides, … These agents contribiute to water pollution.
And the consequences? Of course, it is human health! Human are likely to get into trouble with some diseases such as hepatitis by eating seafood that has been poisoned. Water pollution also brings about the death of aquatic (water) animals, Disruption of food-chains, Destruction of ecosystems.
In conclusion, water pollution is a alarming problem that needs to be solved as soon as possible. The sooner we solve it, the more healthy we are.

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.
In Vietnam, Ede people are the 12th among 54 ethnic groups. It is estimated that more than 331,000 Ede people reside mainly in the provinces of Daklak, southern of Gia Lai province and the west. of the two provinces of Khanh Hoa and Phu Yen of Vietnam.

The Ede people are native speakers of the Malay language, having long-standing origins from the sea. Although migrating to central Vietnam and migrating to the Central Highlands during the late eighteenth and fifteenth centuries, in the depths of the E de people, waterfronts and boats are still images. Pictures have not faded.
Ede long stilts have a long boat shape, the main door opens to the left, the window opens to the side. Inside the house is a wooden dome with the same roof. Ede houses are low-floor type houses, usually from 15 to more than 100 m depending on family or many people. It is the Ede house with unique characteristics unlike the houses of other residents in the Central Highlands. It is home to large matrilineal families. The long house is also a symbolic work reflecting the most typical of Ede ethnic culture. Ethnologist Dr. Liu Hung, deputy director of the Museum of Ethnology of Vietnam, said: "In terms of culture, the long house is a large exhibit showing many things, Dike is a matriarchal society. Symbols of matriarchal society show up from the Ede long house, which is a woman-made twin image of a woman's full breast on the stairs to the north of the house and sides. column in the house. The items in the home also show the matriarchy. "
In the Ede family, the landlord is a woman. According to the matriarchal system, the children bear the maternal family, the son does not inherit. Men marry and live at home wife. Only the daughter inherited the property, the youngest daughter inherited the church and grandparents responsible for raising old parents. When a girl marries, the house will be extended to new families. Looking at the window of the long house can know the Ede girl is married or not. If the window is opened, the woman is married.
In production, the Ede people used to hunt, gather, cultivate, fish, weave, weave, etc. The agricultural characteristics of the E de people are rotational, In addition to cultivated lands, there are also wild lands where the land can be rested. Nowadays, the Ede people do not only cultivate fields, they are also associated with processing agricultural products, planting industrial crops such as coffee, rubber, pepper, cocoa ... In addition to cultivation, cattle, elephants. The villagers in E de village also make knitwear, bronze bowls, wooden furniture, jewelry, pottery ... to serve spiritual rituals and daily life activities.
In the spiritual life, E de people consider Gie (God) as the supreme god, and from time immemorial E de people consider the things and phenomena of nature as separate gods. Rain god, mountain god, river god, forest god ... and according to the concept of the people, every thing from grass to trees, gongs, gongs ... are souls inside. Nguyen Tru, a researcher in the Central Highlands, said: "It was natural conditions, rivers and mountains that created the culture of the E de people. It is also a way for the Ede to remember their ancestors, the forest, grateful for what they have, what makes life today. Therefore, even the gongs, gongs also bring the sound toward the mountains, forests towards the river ... "

Each summer vacation, I am taken to the countryside by my parents so as to relax after a hard working term. I really like the life here. In rural areas, there are not as many houses and vehicles as in the city. As the result, the atmosphere is quite fresh and cool. Most people mainly travel by bicycle or on foot. The landscape is very poetic and picturesque. There are many gardens, rivers here. We can grow vegetables or chickens, fish,... on our own. The local are very kind, generous and friendly. They are willing to give directions to strangers and help each other in difficult times. Whenever we are away, we can relievedly ask our neighbors to keep our houses and children . Another thing that we especially like is that in the countryside, we are reconciled to nature so that the soul is always open and the body is healthy. Living in the countryside is fun and wonderful. In the future, I really want to live here.

Mỗi lần nghỉ hè, mình lại được cha mẹ cho về quê chơi, thư giãn sau một kì học căng thẳng. Mình rất thích cuộc sống ở đây. Ở nông thôn không có nhiều nhà cửa,xe cộ đi lại như ở thành phố nên không khí khá trong lành và mát mẻ. Mọi người chủ yếu đi lại bằng xe đạp hay đi bộ. Khung cảnh rất nên thơ, đẹp như tranh vẽ. Ở đây có rất nhiều những vườn tược, sông ngòi. Chúng ta có thể tự tay trồng những loại rau củ hay nuôi gà, nuôi cá,... Người dân ở đây rất tốt bụng, phóng khoáng và thân thiện. Họ sẵn sàng chỉ đường cho người lạ và giúp đỡ nhau những lúc khó khăn. Mỗi khi đi xa, ta có thể yên tâm nhờ hàng xóm trông hộ nhà cửa, con cái. Một điều nữa mà mình đặc biệt thích là ở nông thôn, chúng ta được giao hòa với thiên nhiên bởi vậy mà tâm hồn lúc nào cũng rộng mở và cơ thể thì khỏe mạnh. Cuộc sống ở nông thôn thật thú vị và tuyệt vời. Trong tương lai, mình rất muốn sống ở đây.
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.
