Water pollution is a source of water contaminated with chemicals or foreign substances that are detrimental to human, plant or animal health. Almost all types of water pollution are harmful to the health of humans, animals and plants. While it may not cause immediate harm to our health, it may be harmful after long term exposure. In addition, water pollution can harm economies as it can be costly to treat and prevent pollution. The cause comes from water environmental pollutants including: fertilizers and pesticides from agricultural production; wastewater and waste from food processing; lead, mercury and other heavy metals; Chemical waste from industries. To limit the consequences that environmental pollution causes. More than anyone else, each citizen must be self-aware of his or her own work. The State and management agencies must constantly propagate to raise people's awareness. Strictly inspect and handle factories and enterprises that violate environmental regulations, tighten the ban on indiscriminate littering anywhere. It is necessary to have effective methods and means of waste treatment, to avoid the problem of stagnant garbage and pile up polluting piles. Use public transport or ride bicycles or tram to replace the vehicles that pollute the streets. Promote the planting of many green trees to create freshness and harmonize the living environment. In addition, scientific researchers or each person need to research and invent the equipment and tools to treat, recycle or sort waste to reduce effort and cost, while minimizing the amount of waste each day. Protecting the environment is a responsibility and happiness not only for anyone, let's act together for a green - clean - beautiful and safe living world. Our mission is to create a healthy and safe living environment.

In particular, the problem of water pollution in Vietnam has been becoming more and more serious. Through the media, we can easily see images, as well as articles reflecting the current environmental situation. Although departments and unions make efforts to call for environmental protection, water resources protection, ... but it seems that it is not enough to improve the situation of increasing pollution. The status of planning for urban areas has not been linked to the problem of waste treatment, wastewater treatment ... so there are still outstanding in big cities, industrial zones, urban areas, ... Environmental contamination is at an alarming rate. Many people believe that the things they do are too small, not enough to harm the environment. Some people think that protecting the environment is the responsibility of the state, at all levels of the government ... while others think that whatever the environment is polluted, it will "not lose money". , and environmental pollution does not affect me much.

V. Read this passage about the effects of visual pollution.

Visual pollution has a greater effect on people than you may think. I remember when I went to a foreign city, I was really scared because there was so much graffiti on the buildings' walls. Then I looked up, and I saw a lot of power lines over my head. Although they were not dangerous, I still felt insecure since I thought they might fall down. These things prevented me from enjoying the beautiful sights of the city. I also remember the time I studied in Melbourne. Once I was so busy with my assignments that I did not tidy my room for two weeks. Looking at the messy room caused me so much stress that I did not want to study. Then I decided to clean the room and put my things in their proper places. I also bought a small plant and placed it in a corner. These simple actions increased my motivation and helped me focus on my learning.What about you? Have you ever been affected by visual pollution?
