Fresh water is the most important source of life on the earth. Any living thing may survive without food for days however it is impossible to imagine life without water and oxygen. The ever increasing human population enhances the demand of more water for purposes like drinking, washing, performing industrial processes, irrigating crops, arranging swimming pools and other water-sports centres. Water pollution is done by the people of all over the world because of increasing demands and competitions of luxuries life. Waste products from many human activities are spoiling the whole water and decreasing the amount of oxygen available in the water. Such pollutants are altering the physical, chemical, thermal, and biological characteristics of the water and adversely affecting the lives inside as well as outside the water.

When we drink the polluted water, harmful chemicals and other pollutants goes inside our body and deteriorates all the body organs functioning and puts our lives in danger. Such harmful chemicals also disturb the lives of animals and plants greatly. When plants absorb dirty water through their roots, they stop growing and die. Thousands of seabirds are killing because of the oil spilling from ships and industries. High level of water pollution is done due to the chemicals coming out of the agricultural usage of fertilizers, insecticides and pesticides. The effect of water pollution varies from place to place upon the type and amount of water contamination. The degradation of drinking water needs an urgent basis prevention method which is possible by the proper understanding and support from the end of each and every person living on the earth.

          Causes need to be changed and, most importantly, our human consciousness about the cause of water pollution in Vietnam.
          Why is human consciousness the most important of environmental pollution, first referring to residential areas or households living along the river in 2013, the vast majority of whom are people People living along the river, then the daily cleaning has made the water environment worse, in recent years, the river in the area of ​​living people have been heavily polluted.
           Speaking about the consciousness of the people, there are families living all year round on boats, boats, barges ... not only their daily activities are discharged into the water but also objects that are no longer used also thrown in. River.
           The activities of the people occur throughout the year as such, the water environment in Vietnam is increasingly polluted, the people living in polluted areas or nearby residents will also affect the health. very strong.
           There are also companies, factories or factories that have escaped the environmental laws and the river is discharged into the river.
           The causes of water pollution in Vietnam just mentioned above have destroyed our environment, what we have done is that we are facing many serious illnesses and costly expenses. .

           In addition, water pollution also affects the lives of living and living plants, which cause ecological disturbances, causing some fish or plants to deplete due to pollution of the water environment. This increases the scope and thus the authorities can hardly reform.
As pollution of the water environment increases, the level of human health decreases and it can lead to pollution of the intersection of rivers and lakes, affecting marine ecosystems. .
           The major sources of pollution are Saigon Port, Saigon River, Tau Canal, Black Canal, 15, 17, 18, Thay Cai Canal, etc. in Ho Chi Minh City. Black water and bad smells made the people around and the people who were walking so uncomfortable.
           In terms of solutions, governments and authorities must place prohibition signs in places where there are many residents living near the rivers and strictly punish acts of deliberately throwing litter into the river or people living in the river. ships, boats, barges ...
           In areas where water pollution is a problem, it is important to learn about the area and to conduct the renovation and use of the technologies or to hire foreign environmental specialists who have advanced technologies to change the water source. infected in the optimal time as possible.
           The media must also include environmental information as well as solutions on how to communicate with people in the environment, especially the water environment, such as information and communication. Everybody changes their minds to keep their sanitation in common with the environment as well as the water environment in Vietnam.
           On the limitation of these solutions, it is well known that it would require a lot of money to renovate or hire foreign experts, when it comes to the causes of water pollution in Vietnam. The solution is to try to change the environment of clean water, but if our human consciousness is that, one day we will also meet the scene of such black rivers.
           Therefore, let us protect our environment and our children in the future so that we can live in a clean environment, help us improve our health and ecosystems. in water environment.

Water Pollution is the contamination of water bodies. It occurs as a result of introduction of pollutants in water. Water is life. Still, we contribute in polluting the water bodies in several ways.

Water Pollution is mainly caused as a result of improper discharge of household and industrial chemicals wastes into the water bodies.

These dangerous chemicals (in the form of solid, liquid or gases) mixes with water and make it unsafe for living bodies. Water pollutants cause harm to human-beings, animals, trees and other constituents of environment.

Topic 1: Write about types of pollution.

P/s : Chi 1 cai o nhiem thoi ...

Nowadays there are a lot of types of pollution such as : air pollution, water pollution, visual pollution .... and noise pollution. Noise pollution is constant and loud sound. To measure the loudness, or volumn of sounds , people use a unit called a decibel. When a sound is louder than 70 decibels, it can cause noise pollution. Do you know that the noise from a vacuum cleaner or motorcycle can result in permanent hearing loss after eight hours ? The sounds of a concert are even more serious. Noise pollution can also lead to headaches and high blood pressure. If you are listening to music throughout headphones, and other people can hear it, it means the music is too loud and unsafe.

Topic 2 : Talk about natural diasters and ways to prepare for them.

Today, there are more and more natural disasters that most people affect. In my opinion, we can't prevent natural disaster but we can have some preparation for them. There are many types of natural disasters but typhoon is a popular in our country. Firstly, typhoon is a tropical storm with wind and heavy rain. When it strike, it can weak havoc across large areas and effect lot of life or extensive damage to property . Flood can be happened by long heavy rain and people also can be became homeless. Last year lots of people were seriously injure in a typhoon. Natural disasters are also very dangerous but we also have some simple preparation . The first step is learnt about the risk in your area and read the information about natural disasters on gorvernment site. Next, find out that the rescue and emergency workers advice. It 's also important that you put together emergency supply it and should include food, water, medicine, document, and some money. Finally , plan safe places to meet your family and get to know the evacuation routes and shelter. In short, everyone sholuld protect environment to reduce this natural disasters.

3) Talk about ways of communication now and in the future.

Communication is a neccesary for eberyone. In present , there are three basic forms of communication: verbal, non-verbal and multimedia.

First, verbal ( meeting F2F) is a important way of communication help you success. I like hanging out with my friends and my friends and when I meet F2F with them I feel very confident. It explains why I can speak English easily. Let ' s try! You will have a great time. Secondly, you have a different thing to say non- verbal ( using signs ) will be a good choice. For example, you make your mother sad , you can use a sign to say ' sorry ' to her. Thirdly, with develop of science and technology , many multimedia appear such as video chatting , emailing,... You can know more information despite you still stay at home. But in the future, we can use telepathy or holography. Telepathy uses a tiny device place into our head. We will be communicating just by thought over the network. Holography will help us in our work. Even though, I prefer to chat with my friends. Life is more meaningful that way !

1.Pollution enters the Earth's atmosphere in many different ways. Most air pollution is created by people, taking the form of emissions from factories, cars, planes, or aerosol cans. Second-hand cigarette smoke is also considered air pollution. These man-made sources of pollution are called anthropogenic sources.
Some types of air pollution, such as smoke from wildfires or ash from volcanoes, occur naturally. These are called natural sources.

2.Every time we drive to school, use our heater or air conditioner, clean our windows, or even style our hair, we make choices that affect air pollution. These steps, as well as many others, are things we all can do to help reduce air pollution.

Conserve energy – remember to turn off lights, computers, and electric appliances when not in use. Use energy efficient light bulbs and appliances. Participate in your local utility’s energy conservation programs. Limit driving by carpooling, using public transportation, biking and walking. Combine errands for fewer trips. Keep your automobile well tuned and maintained. Follow the manufacturer’s instructions on routine maintenance, such as changing the oil and filters, and checking tire pressure and wheel alignment. Avoid excessive idling of your automobile.

Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans, aquifers and groundwater). This form of environmental degradation occurs when pollutants are directly or indirectly discharged into water bodies without adequate treatment to remove harmful compounds.

Water pollution affects the entire biosphere – plants and organisms living in these bodies of water. In almost all cases the effect is damaging not only to individual species and population, but also to the natural biological communities.

If you want to help keep our waters clean, there are many things you can do to help. You can prevent water pollution of nearby rivers and lakes as well as groundwater and drinking water by following some simple guidelines in your everyday life.

Conserve water by turning off the tap when running water is not necessary. This helps prevent water shortages and reduces the amount of contaminated water that needs treatment. Be careful about what you throw down your sink or toilet. Don’t throw paints, oils or other forms of litter down the drain. Use environmentally household products, such as washing powder, household cleaning agents and toiletries. Take great care not to overuse pesticides and fertilisers. This will prevent runoffs of the material into nearby water sources. By having more plants in your garden you are preventing fertiliser, pesticides and contaminated water from running off into nearby water sources. Don’t throw litter into rivers, lakes or oceans. Help clean up any litter you see on beaches or in rivers and lakes, make sure it is safe to collect the litter and put it in a nearby dustbin.

1. Industrial waste: Industries produce huge amount of waste which contains toxic chemicals and pollutants which can cause air pollution and damage to us and our environment. They contain pollutants such as lead, mercury, sulphur, asbestos, nitrates and many other harmful chemicals. Many industries do not have proper waste management system and drain the waste in the fresh water which goes into rivers, canals and later in to sea.

2. Sewage and waste water: The sewage and waste water that is produced by each household is chemically treated and released in to sea with fresh water. The sewage water carries harmful bacteria and chemicals that can cause serious health problems. Pathogens are known as a common water pollutant; The sewers of cities house several pathogens and thereby diseases.

3. Mining activities: Mining is the process of crushing the rock and extracting coal and other minerals from underground. These elements when extracted in the raw form contains harmful chemicals and can increase the amount of toxic elements when mixed up with water which may result in health problems.

4. Marine dumping: The garbage produce by each household in the form of paper, aluminum, rubber, glass, plastic, food if collected and deposited into the sea in some countries. These items take from 2 weeks to 200 years to decompose.

5. Accidental Oil leakage: Oil spill pose a huge concern as large amount of oil enters into the sea and does not dissolve with water; there by opens problem for local marine wildlife such as fish, birds and sea otters.

6. Burning of fossil fuels: Fossil fuels like coal and oil when burnt produce substantial amount of ash in the atmosphere. The particles which contain toxic chemicals when mixed with water vapor result in acid rain. Also, carbon dioxide is released from burning of fossil fuels which result in global warming.

7. Chemical fertilizers and pesticides: Chemical fertilizers and pesticides are used by farmers to protect crops from insects and bacterias. They are useful for the plants growth. However, when these chemicals are mixed up with water produce harmful for plants and animals.....

Death of aquatic (water) animals
The main problem caused by water pollution is that it kills organisms that depend on these water bodies. Dead fish, crabs, birds and sea gulls, dolphins, and many other animals often wind up on beaches, killed by pollutants in their habitat (living environment).

Disruption of food-chains
Pollution disrupts the natural food chain as well. Pollutants such as lead and cadmium are eaten by tiny animals. Later, these animals are consumed by fish and shellfish, and the food chain continues to be disrupted at all higher levels.

Diseases
Eventually, humans are affected by this process as well. People can get diseases such as hepatitis by eating seafood that has been poisoned. In many poor nations, there is always outbreak of cholera and diseases as a result of poor drinking water treatment from contaminated waters.
Did you read about the Water contamination in Flint, Michigan, USA? Read here.

Destruction of ecosystems
Ecosystems (the interaction of living things in a place, depending on each other for life) can be severely changed or destroyed by water pollution. Many areas are now being affected by careless human pollution, and this pollution is coming back to hurt humans in many ways.

Are natural disasters increasing? Yes. Natural disasters are unpreventable occurrences that take place, ranging from mild to absolutely destructive. In recent years, it may seem as if these storms have increased from prior decades.

According to recent studies, it is true: the number of natural and geophysical disasters taking place each year is noticeably skyrocketing.

Geophysical disasters include earthquakes, volcanoes, dry rock-falls, landslides and avalanches. Climatic disasters are classified as floods, storms, tropical cyclones, local storms, heat/cold waves, droughts and wildfires.

9.When you buy a home, you want to protect it. Nothing should take away your sanctuary—not bad weather or unexplainable freak accidents.

10.Human-initiated fires are to blame for a high amount of property damage; loss of wildlife habitat and the lives of humans and animals. Some forest fires are the result of carelessness or improper habits when engaging in outdoor activities. Familiarizing yourself with appropriate forest fire preventive measures not only helps you become a more aware individual when it comes to protecting the safety and natural resources in your region, but also helps you better spread the word

Causes of water pollution

1) Water pollution may be caused by the intentional or unintentional disposal of hazardous chemicals and materials into a body of water.

2) Rainfall may cause polluted landscapes to disperse their poisonous materials into the water and poison the surrounding water.

3) Water pollution may also be caused by specific points or contributing factors such as large factories, oil refineries, construction sites, chemical waste management facilities, dump sites and other large scale operations that store/produce large amounts of chemical/hazardous waste.

Effects of water pollution

1) Toxic rainfall can occur in areas where water and/or air is polluted with toxic chemicals and materials.

2) Polluted water can lead to sickness, disease, infections, deformities and even death among animals and plant life.

3) Once water becomes polluted it can affect people and animals either directly through consumption or indirectly through food sources, land degradation and the overabundance of plants and algae which can cover the surface of various bodies of water making it undrinkable and affecting the animals that live in that body of water.

Solution:

The most critical step to prevent water pollution is to adopt appropriate waste management policies. Setting up of wastewater treatment plants can resolve this issue and hence we can protect our natural water resources from contamination and embrace an eco-friendly life.

HOW YOU CAN HELP

If you would like to limit the amount of pollution you produce and thus help keep the oceans, rivers and lakes clean there are a number of things you can do.

Replace your air fresheners with eco-friendly candles, incense and/or potpourri Purchase environmentally friendly cleaning products that do not harm the land if they happen to be flushed or emptied into a drain Reduce the amount of power you use and purchase energy saving light bulbs and appliances. This helps reduce the amount of emissions being released by utility companies and your own home products. Conserve your water usage and don’t leave water running when you are not using it Reduce, recycle & reuse materials that you have purchased. Plastics and papers may be sent to the recycling bin while some of your glass materials may be able to be reused or re-purposed Make sure non recyclable waste is contained properly so that it does not spill into the land, street drain sewage drain Purchase local food that has been grown from healthy agricultural farms that don’t use polluting fertilizers and pesticides Purchase eco-friendly lawn fertilizers and pesticides for your own lawn in order to prevent your lawn from becoming toxic and prevent possible hazardass chemicals from entering street drains Recycle old clothing by giving it away to shelters and non for profit re sellers. Not only does it lower the amount of garbage you produce it also allows you go give to a cause and help the community Use a reusable grocery bag rather than the plastic bags offered at grocery stores when shopping for food to minimize your plastic waste Eliminate unnecessary mail and have your bills sent to you by email. This helps protect the trees and reduce the amount of paper you have to dispose of later
