Today, Mr. Xiao An will take you to learn about garbage.
What is garbage?
Garbage is the waste items that we don't need in our daily life, such as apple cores that we can't eat, milk bottles that we can't drink, small paper balls that we don't use, and so on. And, due to the large population of our country, more garbage is generated.
What are the main ** of garbage?
It mainly includes domestic waste, construction waste and industrial solid waste. Domestic garbage includes domestic garbage, market and commercial garbage, garbage in public places, street cleaning garbage, and garbage from enterprises and institutions. Construction waste refers to the waste generated during the construction process, such as muck, waste concrete, bricks, etc. Industrial solid waste refers to the waste residue and waste materials generated in the industrial production process.
Next, let's talk about the dangers of garbage.
Garbage will pollute the air, and the garbage piled up in the open air for a long time is easy to rot, deteriorate, moldy, release a large number of harmful gases, emit foul odors, and will also raise powder and fine particles, seriously pollute the air and damage our living environment. Acid rain, for example, is one of the typical consequences of air pollution.
Garbage can also pollute water bodies, such as throwing garbage into lakes, rivers or oceans, which will cause more serious pollution to water bodies, so that aquatic organisms will be poisoned, and people will be indirectly poisoned by eating these contaminated aquatic products.
Garbage will also pollute the soil, some toxic and harmful garbage is piled on the ground without treatment, which will slowly produce harmful substances and cause pollution to the surrounding soil, and this pollution is irreversible. Garbage is also harmful to human health, and garbage heaps are the habitat of harmful animals such as rats, cockroaches, mosquitoes and flies, which can wander around and spread diseases. In addition, garbage may also spontaneously explode and combust, threatening the personal safety of residents. White pollution can also affect the aesthetics and spoil the landscape.
What should we do?
In daily life, we have to do a good job of garbage classification, and a lot of waste can actually be reused, but it is misplaced.
With the development of modern technology, the amount of garbage generated globally every year is increasing, and more land is needed to store garbage, which may also pollute groundwater and land. If waste is disposed of by incineration, it may cause air pollution. The most effective solution to these problems is to reduce the generation of waste and reuse it.
If we carry out garbage classification, the waste in bottles, cans, cartons, handbags and other useful parts of the reuse, can be turned into beautiful and practical home accessories, which can not only save resources, but also reduce the amount of garbage generated, reduce garbage disposal costs, save land resources, thereby improving our quality of life.
Finally, Mr. Xiao An would like to say that the problem of garbage is closely related to our lives, so let's start from ourselves and contribute to environmental protection!
