1. Write a paragraph about WATER POLLUTION by answering the questions below:
=======================
What is water pollution?
What are the sources of water pollution?
How do farmers pollute water?
How do mills and factories pollute water?
How do ignorant people pollute water?
How do water vehicles pollute water?
How does polluted water affect us?
How can we minimize water pollution?
=======================

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.

There are many ways to help protect our oceans and coast for future generations. Firstly, I think we shouldn't litter because this makes the sea pollute and endangers sea plants and animals. Some animals can be harmed if they eat these pollutants. We should place rubbish and plastic bags in proper dustbin. Secondly, I suppose the government should introduce laws to prohibit the killing of endangered animals and the destruction of the environment where the endangered species live. Finally, we should tell our friends, relatives or families not to purchase products made from body parts of endangered species. Be a smart shopper and choose your seafood responsibly. All in all, occeans should be protected so that the Earth will be a happy planet for us to live on.

By 2016, in Ha Tinh province, there was a severe water pollution case by the Ha Tinh formosa company. The cause of the pollution is due to violations and incidents during the trial operation of the plant complex of Formosa Ha Tinh, the factory has discharged toxic to the sea, hydroxide, exceeds the level allowing a number of dead sea creatures to cause the fishermen to lose their jobs. Not only the economic losses, the incidents and incidents also negatively affect the health and life. living, tourism development activities, economic community of neighboring neighborhood, causing psychological instability for people. forced the factory must compensate and apologize to the entire Central people. Here I have the idea to protect the water from the waste: the State must strictly supervise the operation of the area industrial parks, economic zones and large projects that are likely to cause high environmental pollution. Investing in infrastructure for environmental protection activities, the Ministry of Natural Resources and Environment, should be paid attention and investment right from head with proportional proportions.

Let's work together to protect the environment!

Refer:

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 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
