When a commodity is used and used, it may become garbage. When people think that something is not a commodity, when people think that it has no use-value, it may become garbage. The criteria for judging garbage vary from person to person. For example, when a new dress is thrown into the trash bin because of its color or style, it becomes garbage. Some people look at clothes and think that the clothes they don’t want are valuable, but not rubbish. Most people regard abandoned branches and leaves, leftovers, and rotten organisms as garbage, while organic fertilizer plants use it as raw materials (raw materials are not garbage). Garbage is a valuable commodity. The main sources of these pollutants in China’s atmosphere are closely related to our daily life. Such as industrial production, oil and mineral resources development, coal-fired power generation and heating, automobile exhaust emissions, waste incineration, etc. Our earth is surrounded by water. It seems that water resources are very rich, but only a small part of water resources can be really utilized. Seawater can’t work directly for us. What we need is freshwater. Why don’t we treat seawater as freshwater? The reason is that according to the current technology and technology, only small-scale seawater improvement projects can be realized, and the investment is very large, which is not directly proportional to the benefit. So we still have to rely on a small amount of freshwater. China is one of the countries which are short of freshwater resources. Because of the large population base, the underutilized water resources are more precious. At present, China’s water resources pollution is still relatively serious, mainly the following several. Industrial pollution, in order to save the cost of treatment, some unscrupulous enterprises directly discharge the untreated industrial wastewater into the water body, causing water pollution. Agricultural pollution is serious, a large number of pesticides are used in agricultural production, such as organophosphorus pesticides, organochlorine pesticides, and so on. Especially in rural areas, farmers throw used pesticides directly into rivers and ditches, causing water pollution. Second, pesticide residues on crops infiltrate into groundwater under the effect of precipitation. Domestic water pollution, our daily life is inseparable from water, in the use of these water resources will produce a large number of domestic sewage, also known as reclaimed water, such as washing water, medical wastewater, etc. The main causes of soil pollution are as follows. Due to human production activities, such as deforestation and uncontrolled mining, vegetation is destroyed and soil erosion is serious. Most of the components of pesticides are persistent organic pollutants. Once it enters the soil, it is difficult to degrade naturally. It will only accumulate more and more and aggravate the degree of soil pollution. Heavy metal pollution is mainly caused by heavy metal wastewater discharged from mining and production enterprises. In fact, our environment is very fragile. Our production activities directly affect the environment in which we live. Hope to attract more people’s attention, have a certain sense of environmental protection.
