With the rapid development of life, our awareness of protecting the natural environment has gradually increased. The most obvious change is that garbage classification has gradually entered our lives. But do you know what the specific boundaries of garbage classification are? What is the measure?

It is very important for our environment to carry out garbage sorting. Take kitchen waste as an example. If it is discarded at will, it will easily breed harmful bacteria, attract flies and mosquitoes, and even pollute water sources and spread diseases. Kitchen waste is not only our leftover food, but also discarded vegetable leaves, peels, eggshells, tea dregs and bones. The leftover food scraps are a nutritious meal for many animals. It has been known for a long time that leftovers are poured into special barrels and then fed to livestock and poultry such as pigs, chickens and ducks. These food scraps are much more nutritious than the feed specially raised for animals. What if the food goes bad? Can animals get sick after eating it?

if food is rotten, it can't be eaten by animals, so it should be sorted well, placed in garbage and treated harmlessly. Food residue can also be used as fertilizer for plants. People imitate the way of nature and use the power of decomposers such as microorganisms and earthworms to turn smelly and dirty kitchen waste into black gold. Compost is a fertilizer for nourishing soil. Composting is really turning kitchen waste into treasure.

kitchen waste is not only of great use to animals and plants, but also can be turned into food for machines. Microbes can not only turn kitchen waste into compost, but also use it to make biogas. Vigor is a kind of clean energy, which can be used for cooking. In this way, the kitchen waste that was sent away silently returned to the kitchen to help us cook delicious food.

Although kitchen waste can be reused, throwing away leftovers is a waste of precious food. Who knows Chinese food on the plate. Lily is hard. Although kitchen waste can be reused, most of them will be buried or burned. Therefore, to advocate CD-ROM action and reduce the amount of garbage is to protect the environment. Let's be experts in garbage sorting.
