Ngày nay, sự phát triển của thế giới loài người gây ra nhiều tác động xấu đến môi trường. Chúng ta vứt rác khắp nơi, khai thác quá nhiều tài nguyên thiên nhiên hoặc làm ô nhiễm không khí. Do đó, môi trường của chúng ta đang bị ô nhiễm nghiêm trọng và chúng ta cần bảo vệ nó từ bây giờ. Trước hết, chúng ta nên giảm thiểu, tái sử dụng và tái chế. Thay vì sử dụng túi nhựa, chúng ta có thể sử dụng lá để bọc thức ăn. Chúng ta có thể tái chế chai nhựa, lon, giấy để giảm rác. Sử dụng vận tải công cộng và giảm số lượng xe máy và ô tô cũng là những cách tốt để giảm lượng carbon trong không khí. Bên cạnh đó, chúng ta nên làm sạch các hồ hoặc sông bị ô nhiễm để giảm bớt ô nhiễm trong nước. Nhanh chóng nhưng không kém phần quan trọng, công việc bảo vệ nên tuyên truyền về việc bảo vệ môi trường cho mọi người để họ có thể nhận ra điều đó. Đặc biệt, chúng ta cần trừng phạt những người làm ô nhiễm môi trường với mức độ nghiêm trọng. Tóm lại, Trái đất là ngôi nhà của chúng ta nên bảo vệ nó là trách nhiệm của mọi người

There are various causes of increase in water pollution with industrialization and increasing population being the major one. With the increase in population around the world, the demand for various industrial products has been stimulated which has led to the increase in industrial waste. Many such industries discharge the waste into nearby water bodies without proper treatment which leads to the addition of harmful chemicals in the water body.

Modern methods of agriculture are also a leading cause because with the increase in use of chemical infused pesticides and germicides the soil is tampered and the water flowing through it gets mixed with these chemicals and loses its purity. These agricultural pesticides are a leading cause of eutrophication of freshwater lakes.

Other causes of water pollution includes acid rain, improper sewage treatment, discharging of hot water without cooling by thermal power plants, religious rituals such as disposing corpses into the rivers and various other urban and rural practices. Hence, these are the root causes of increasing water pollution. In order to eradicate the contamination of water these issues have be to be tackled with the help of advanced technology and scientific principles.

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!

Just like looking at a computer screen all day, it can damage your eyes and damage your eyes. Online games cause people to act violently, such as killing, bombarding or fighting each other. To overcome the consequences not to last, we need the help of adults.

Playing online games for fun is not bad, but letting children play violent games and addicted to games is a behavior worthy of condemnation.
