What are the causes of garbage?

Question 1: What factors are related to the generation of domestic waste? The generation of domestic waste is mainly related to urban population, urban economic development level, residents' income and consumption structure, fuel structure, management level and geographical location.

1, urban population

With the growth of urban population, the amount of urban solid waste increases linearly. The greater the population, the more urban garbage will be produced.

2, the level of urban economic development

In the period of high-speed economic development, the output of garbage will also increase substantially, and the growth rate will gradually slow down after a certain period of development.

3. Residents' income and consumption structure

The change of residents' living standard and consumption structure not only affects the output of municipal solid waste, but also affects the composition of municipal solid waste. The more developed the commodity economy, the more disposable garbage. In recent years, the income of residents has been increasing, people's living standards have been improving, and packaging materials, disposable materials and supplies have been increasing, resulting in a substantial increase in the amount of garbage.

4. Fuel structure and geographical location

Garbage production is related to geographical location and local fuel structure. For example, the heating period in the north is long and the fuel is mainly coal, so the garbage output is higher than that in the southern cities, and the inorganic content is also higher than that in the southern cities.

5. Management level

The improvement of urban municipal management level and the enhancement of citizens' awareness of environmental protection will gradually improve the recycling rate of garbage, thus reducing the per capita garbage output. In addition, the management level of garbage disposal industrialization and socialization also directly affects the effect of reduction, recycling and harmlessness of domestic garbage.

Question 2: How did you produce so much rubbish? How do you produce garbage? Reasons, types and processes of garbage production: Reasons: Garbage is some wastes produced and left over by human beings in the process of life activities and production activities, which can continue to be processed and utilized, but human science and technology can not continue to be developed and utilized at present. Type: 1 domestic waste. Industrial waste. 3 Construction waste. Industrial waste also includes: raw material production waste, energy waste, industrial manufacturing waste and industrial secondary production waste. Process: 1 Domestic garbage generation process: In the process of life activities that human beings must carry out to maintain normal life, more garbage than daily needs is generated. Such as: cooking fuel waste, food waste, food packaging waste, household goods waste, etc. There is a lot of recyclable garbage in domestic garbage, which needs further processing and utilization. 2. Production process of industrial wastes: In the industrial production process, there will be some wastes generated during the development and production of raw materials, wastes that are temporarily unusable and useless, a large number of industrial wastes, a large number of electronic product production wastes and a large number of secondary processing wastes. There are many industrial wastes that can be recycled, utilized and processed. 3. Construction waste generation process: In the process of urbanization, a large amount of construction waste and clothes are generated.

Question 3: How did the garbage problem come about? The problem of garbage is because the number of human beings is increasing, and more and more garbage is produced by human beings. Can decompose garbage better than nature. In addition, some new materials that cannot be decomposed naturally or need to be distorted for a long time are also important reasons for the garbage problem.

Question 4: The generation and causes of campus garbage. The trash can was destroyed because our students' quality was not high, and the garbage around them broke down and ran out.

Question 5: One of the reasons for spam messages is that some people with low interest spread yellow messages in order to please others; Second, some criminals use SMS to defraud money; Third, some people are blinded by interests and easily believe in all kinds of beautiful things. Fourth, in some cases, people are easy to listen to unfounded rumors; Fifth, the more important reason is that China's legislation on information security is not in place, the supervision mechanism of relevant departments is not perfect, and socialist morality has not really been established. In addition, the low cost of sending spam messages and the use of technical means to escape supervision have also caused the proliferation of spam messages. Lv Tingjie, executive dean of the School of Economics and Management of Beijing University of Posts and Telecommunications, believes that the price of mass short messages in some places has been as low as 20 cents per message, which is one fifth of the public short message service fee. This low-cost operation undoubtedly provides a cheap communication tool for spam messages, resulting in a large number of advertisements being diverted to SMS channels.
