What is the environment like? From a philosophical point of view, the so-called environment mainly refers to all the circumstances and conditions around the subject we are studying. For people, the environment refers to the synthesis of all external conditions that people live in and can affect people. People can't live without a good environment. In the course of millions of years of human history, the environment has played a great role in creating human civilization and progress.
Atmospheric resources, water resources, land resources and so on. , is the material basis of human existence; Forest resources, mineral resources and other resources provide a material basis for the continuous development of mankind and create a high degree of human civilization on the earth. However, while developing and utilizing environmental resources, human beings have also brought a series of environmental problems to their living environment.
There are many pollutants that pollute the environment around us, such as a lot of domestic garbage, plastic bags (also called white garbage), disposable wooden chopsticks, disposable lunch boxes, peel scraps and so on. There is no doubt that pollutants do great harm to the environment. For example, the rotting carcasses of animals will affect environmental sanitation and breed bacteria. Disposable wooden chopsticks, which restaurants and restaurants think are very sanitary, will be thrown away after use, which will affect the city appearance and destroy the environment. .
Now, like Liutuan Town and Qing Xiang Town, the power grid department has recently cancelled the use of water sprinklers. The use of sprinklers has aggravated environmental pollution, polluted water resources and greatly endangered people's health. Reprinted from Fenfen. Please keep this mark. Human activities will cause a large number of industrial, agricultural and domestic wastes to be discharged into water bodies and pollute them. Another example is the Bohai Bay in the north of China, where local farmers fish in Shanghai due to the waste discharged by industry and printing and dyeing factories, resulting in a large number of fish and shrimp deaths. This kind of fish contains a lot of chemicals, which is harmful to people's health. According to statistics, at present, more than 420 billion cubic meters of sewage is discharged into rivers, lakes and seas every year, polluting 5.5 trillion cubic meters of fresh water, which is equivalent to more than 14% of the total global runoff. People's Republic of China (PRC) Water Pollution Prevention Law promulgated by 1984 has a clear definition of "water pollution", that is, the phenomenon that the chemical, physical, biological or radioactive characteristics of a water body are changed due to the intervention of a certain substance, thus affecting the effective use of water, endangering human health or destroying the ecological environment, and causing the deterioration of water quality is called water pollution. There are two kinds of water pollution: one is natural pollution; The other is man-made pollution. At present, man-made pollution is the most harmful to water bodies. Water pollution can be divided into three categories: chemical pollution, physical contamination and biological pollution.
Recently, I found that government departments and Changyi Environmental Sanitation Bureau began to improve the environment vigorously, and investigated the pollution sources along the street. Qing Xiang Street also set up convenience bins at designated locations, replacing the original situation that garbage surrounded the street and stinked. Villages began to rectify the pollution sources in the village environment and make the streets and villages look brand-new! And that's not the most important thing. What's more important is that each of us consciously protects the environment, protects the home on which we live, sets a good example for ourselves and our descendants, lays a good foundation, and makes our home more beautiful and colorful!
