Bài 1: When water becomes undrinkable and harmful for our existence, we call it polluted. Water is polluted in many ways. Firstly, farmers often use chemical fertilizer and insecticides in the corn fields. When rain and flood water wash away these chemicals into the rivers, canals or ponds and water gets polluted thereby. Secondly, mills and factories throw their waste into the rivers and canals and thus pollute water. Thirdly, ignorant people pollute water by throwing human waste and filth from drains and unsanitary latrines. Water vehicles also pollute water by dumping oil, food waste and human waste. By drinking polluted water, we suffer from fatal diseases-and die. Water pollution may cause serious environmental disaster. To minimize water pollution, various measures may be taken. However, making people aware of the dangers of pollution is the best measure to reduce water pollution to an optimum level. Bài số 2 Water pollution is one of the most serious environmental problems. It occurs when water is contaminated by such substances as human and animal wastes, toxic industrial chemicals, agricultural residues, oil and heat. Most of our water bodies— rivers, lakes, seas, oceans, estuaries and underground water sources (i.e., tubwells, bore wells) are gradually becoming polluted. In the course “Covered so far, you have seen how deforestation, urbanization, intensive agriculture and industrialization have caused pollution of water bodies. You are familiar with various aspects of air pollution, including harmful effects of acid rain. In this unit we will summaries various types of water pollution caused by different pollution sources, and also explain some important concepts such as point and non-point sources, biological oxygen demand (BOD), eutrophication, self-purification capacity of natural waters, infiltration of pollutants to groundwater, thermal pollution and pollution caused by accidents in oil tanker ships. In the next unit you will read about the degradation of land resources and terrestrial features of earth. Polluted water may look clean or dirty, but it invariably contains germs, chemicals or other materials that can cause inconvenience, illness or death.
Visual pollution is an aesthetic issue and refers to the impacts of pollution that impair one's ability to enjoy a vista or view.
Visual pollution disturbs the visual areas of people by creating harmful changes in the natural environment. Billboards[1],[2] open storage of trash, antennas, electric wires, buildings, and automobiles are often considered visual pollution. An overcrowding of an area causes visual pollution. Visual pollution is defined as the whole of irregular formations, which are mostly found in natural and.[3][4]

In some remote areas in Vietnam, some people do not have enough clean water to use. As a result, they have to use the water from the river or hand-digged wells and they contain some substance that affects health. Moreover, water filtration systems are impossible to meet the needs of people. The authority has applied a lot of solutions and actions but it must take a lot of time and efforts to supply clean water to every house. Furthermore, the rivers and lakes are contaminated by factories that pour waste into them. They should have inadequate waste-treatment systems to filter the waste before pouring it into the river and the government should have new strict laws to prevent the firm pour waste into water. Water pollution causes great damage, it causes diseases like cholera, diarrhea and skin diseases. The fatality rate of cholera has risen recently especially the children under 5. Water pollution can destroy farming and kill animals around the source like fish and some aquatic life. Water pollution can kill plant life, plants died when they were irrigated with water containing heavy chemicals.

Nowadays, pollution is a popular term with everyone in the world and air pollution is one type of pollution. The definition of air pollution is one such form that refers to the contamination of the air, irrespective of indoors or outside. A physical, biological or chemical alteration to the air in the atmosphere can be termed as pollution. There are some main reasons which cause air contamination such as burning of fossil fuels, agricultural activities, exhaust from factories and industries, mining operations, and indoor air pollution. Air pollution always has bad effects on our life. Harmful gases, dust, and smoke enter into the atmosphere and make it difficult for plants, animals and humans to survive. We also can see some examples of the result of air contamination which occurs around us as global warming, acid rain, and depletion of ozone layer. The effects of air pollution are alarming, so governments over the world should have suitable policies of protecting the environment, especially air quality to create a clean world for our generation in the future.
Water pollution is the most dangerous and worst form of pollution putting lives in danger.
The highest level of water pollution is caused by the pollutants come from agriculture field because of the high use of fertilizers, insecticides, and pesticides to enhance the production of crops.Factories dump industrial waste into the water or sewage from household is an other cause .

There are a lot of activities that you can do in your leisure time. Some people are so tired of work that they prefer to use their free time just for resting and sleeping. Others spend their free time on their favourite activities. For example, they listen to music, play their favourite musical instrument, go on a picnic, take a trip, go to the nature and enjoy the fresh air, hang out with their friends, go partying, go shopping, visit their relatives, spend some time with their kids and play games with them, read and write, watch TV, watch movies or cartoons, go to the theatre, surf the net, cook, do some gardening, etc. Some people like me choose sports to enjoy their free time. Among different kinds of sports, I prefer basketball.
When you play basketball with your team mates you have a chance to get rid of all the negative energies that are piled up in you throughout work or study time. Your body is wholly involved. Basketball involves both your mind and your body. It’s an extremely physical activity, so that even your finger tips have to be strong. In basketball you need both stamina and speed to be a successful player. It’s not that important if you’re not tall. Your strength is of much more importance. Both feet and hands must be strong. Even you need to be wise in this game. If you know where to stand so that your rival has a weak chance of blocking you, you’ll more successfully get close to the basket to shoot and score. Sometimes, by being wise and finding the right place to stand and block the rival saves your team.
Basketball is a team work and this is what I like the most about this sport. You learn how to cooperate with other team mates. Sometimes, you need to sacrifice yourself by blocking the rival so that your team mate can find space to go to the basket and score. Passing the ball to other members of your team makes the chance of winning higher and higher.
All in all, basketball is so enjoyable and fun if you play it in a group, not individually.

One of the biggest impacts humans have on aquatic systems is excess nutrient inputs. Nutrients, like nitrogen and phosphorus, are essential to the health and survival of aquatic plants and animals. However, humans introduce large quantities of nutrients, primarily through overuse of fertilizers. Too many nutrients can rapidly reduce water quality by causing overgrowth of certain bacteria and algae that use the oxygen necessary for other species to survive. Even more problematic is that these nutrients can be transported downstream to other streams, rivers and bays. Therefore, nutrients can reduce water quality in places far removed from where they were first introduced.
