The water cycle has 4 stages: storage, evaporation, precipitation and runoff. Water on the Earth gets stored (4)...in... oceans, lakes, rivers, ice and even underground. Water goes from storage into the atmosphere by a process called evaporation. When water evaporates, it changes from a liquid (5)...into... a gas, called water vapor. Water vapor goes up into (6)...the... atmosphere. Water returns to the Earth as precipitation in rain or snow by changing into drops of water (7)...when... the air gets cold enough.

          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.
