Significance of garbage classification

1, reducing environmental pollution

Because there is no classification of garbage in China, modern garbage contains chemical substances, some of which will lead to an increase in human morbidity. If the garbage is disposed by landfill or stacking, even if the garbage is buried far away from the living place and the corresponding isolation technology is adopted, it is difficult to prevent the infiltration of harmful substances. These harmful substances will enter the whole ecological circle with the earth's circulation, pollute water and land, and finally affect people's health through plants or animals.

2. Save land resources

At present, there are two kinds of garbage disposal methods in China, one is landfill and the other is garbage stacking. Either way, the essence is to transport garbage from one place to another and still occupy land resources. At present, landfill is the simplest and most convenient treatment method, but it is extremely unfavorable for future development. A country's land resources are fixed, and China's per capita land, especially cultivated land, is lower than the world average. Landfill is an irreversible place, that is, it can no longer be used as a living area. If land resources are turned into garbage disposal sites, it is equivalent to chronic suicide, and the cost of land restoration in the future will be very expensive.

3. Utilization of renewable resources

Garbage comes from people who don't make good use of resources and throw away their unused resources as garbage. The loss of this abandoned resource to the whole ecosystem is incalculable. Once the garbage is landfilled or incinerated, it is extremely difficult to reuse. Before garbage disposal, garbage can be recycled by classification to turn waste into treasure. For example, recycling paper can protect forests and reduce the waste of forest resources; Recycled biological waste such as peeled vegetables can be used as green fertilizer to make the land more fertile.

4. Improve people's values

Garbage classification is the best scheme and the best way to solve garbage pollution. Garbage sorting has become the only way for a country to develop. Garbage classification can help people learn to save and use resources, develop good living habits and improve their final quality. A person can form a good habit of garbage sorting, then he will also pay attention to environmental protection and the preciousness of resources in life, and form a habit of saving resources.
