What are the reasons for littering during the tour?

The garbage specialty is called "solid waste", which is mainly composed of domestic waste, industrial solid waste, hazardous waste, agricultural waste and radioactive waste. First of all, solid, semi-solid and gas articles that have lost their original value or have not lost their use value but have been abandoned or abandoned in people's production and life activities. These solid wastes are large in quantity or are not treated in time, which will affect the beauty of the surrounding environment, emit stench, or breed microorganisms and bacteria. In addition, the main methods of solid waste treatment are incineration, composting and landfill. Incineration may produce toxic and harmful gases, and the toxic residue left after incineration will still cause pollution if it is not handled properly. Poor composting will also produce toxic and harmful waste gas. Even in precipitation, leakage will pollute groundwater.

Hazard: occupying a lot of land, destroying vegetation and landforms; Polluted water bodies; Dust, toxic gas, odor and spilled gas destroy plants and the ozone layer; Changing the nature and structure of soil will not only affect the biological community in the soil, but also affect the normal growth of plants.
