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.

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.

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.

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 !

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 HELPIf 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.
