The harm of garbage to the earth

(1) encroached on the surface.

Garbage occupies valuable land resources and living space, which seriously affects industrial and agricultural production and life. A large amount of garbage destroys the vegetation on the earth's surface, which not only affects the beauty of the natural environment, but also destroys the ecological balance of nature.

(2) pollute the environment

Solid waste contains all kinds of harmful substances, which can directly pollute soil, air and water, and ultimately cause harm to all kinds of creatures including human beings.

(3) spreading diseases

Garbage contains a large number of microorganisms, which are breeding grounds for germs, viruses and pests, and seriously endanger human health.

(4) Pollution of soil and water.

Landfill leachate changes soil composition and structure, and toxic garbage will affect human health through the food chain. Garbage destroys the structure and physical and chemical properties of soil, greatly reducing the ability of soil to retain fertilizer and water.

Garbage contains pathogenic microorganisms, organic pollutants and toxic heavy metals. Under the action of rainwater, they are brought into the water body, which will cause serious pollution to surface water or groundwater and affect the survival of aquatic organisms and the utilization of water resources.

(5) Air pollution

Fine solid waste will fly with the wind, which will aggravate air pollution. The site where a large amount of garbage is piled up in the open air stinks, rats are infested, mosquitoes and flies breed, and a large number of harmful gases such as ammonia and sulfide are released into the atmosphere. There are more than 65,438+000 kinds of organic volatile gases alone, including many carcinogens and teratogens.

What harm does white garbage do to the earth?

First, it occupies too much land. Garbage piled up in the suburbs of the city occupies a lot of farmland. At present, the average annual output of garbage in Beijing is 440 kilograms per person, and the annual output of the whole city is about 4 million tons, which is equivalent to two semi-scenic mountains. There are more than 4,500 garbage dumps in Beijing, covering an area of 1 1,000 mu. Garbage stays in nature for a long time: cigarette butts and woolen goods 1-5 years; Orange peel for 2 years; Painted wooden board 13 years; Nylon fabric for 30-40 years; Leather for 50 years; 80- 100 cans; Plastics 100-200 years; Glass 1000. To this end, we should not only make less garbage, but also pay attention to the classification and recycling of garbage, so as to turn waste into treasure. Use less disposable chopsticks, cups, lunch boxes and other products, and use more reusable products to reduce the consumption of precious forest resources; Use less plastic bags and shopping bags to reduce the harm of "white pollution" in cities; Buy fluorine-free refrigerators, air conditioners and other environmental protection appliances to protect the atmospheric ozone layer; Use less high-concentration detergent and phosphorus-free washing powder to reduce water pollution. Second, pollute the air. Garbage is a complex mixture. In the process of transportation and open-air stacking, the decomposition of organic matter produces stench, which releases a lot of pollutants such as ammonia and sulfide into the atmosphere, including 100 kinds of volatile organic gases, which contain many carcinogens and teratogens. Plastic film, paper scraps and dust fly with the wind, forming "white pollution". Third, pollute the water source. Harmful components in garbage are easily washed into underground water by rainwater, and a large number of acidic and alkaline organic pollutants will be produced during garbage stacking or pit filling, and heavy metals in garbage will be dissolved. Leachate produced by garbage pollution sources will penetrate into groundwater through soil; If garbage is directly thrown into rivers, lakes or oceans, it will cause more serious pollution. You see: plastic bottles and lunch boxes floating on the sea surface of the Summer Palace and Beihai, plastic bags and bread paper hanging on the branches scattered on the forest mountain roads in Xiangshan and Badachu. Some tourists just want their own convenience, which has caused environmental pollution. If animals eat white garbage by mistake, it will not only harm health, but even lead to death. Fourth, soil and dregs. The application of garbage to farmland after direct or simple treatment will destroy the aggregate structure, physical and chemical properties and water and fertilizer conservation ability of soil. Especially plastic bags and sheets, if buried in farmland, the roots of crops will not grow, the farmland will reduce production, and the food available for people will decrease. Fifth, fire hazards. Garbage contains a lot of combustible substances, which will produce methane and other combustible gases in the process of natural stacking, and it is easy to cause fire when it encounters open fire or spontaneous combustion. With the increase of organic matter content in municipal solid waste (MSW) and the change from open-air decentralized storage to centralized storage, the harm of biogas produced by MSW in long-term storage is becoming more and more prominent, and MSW explosion accidents continue to occur, causing huge losses. Sixth, the nest of pests. Garbage not only contains pathogenic microorganisms, but also provides food, habitat and breeding places for mice, birds and mosquitoes and flies, and is also the root of infectious diseases.

Harm of garbage to the environment

The phenomenon that garbage encroaches on land, blocks rivers and lakes, hinders health, affects landscape, and harms crop growth and human health is called garbage pollution. Garbage includes industrial waste residue and domestic garbage. Industrial waste residue refers to the waste produced in the process of industrial production and processing, mainly including coal grindstone, fly ash, steel slag, blast furnace slag, red mud, plastic and petroleum waste residue. Domestic waste is mainly kitchen waste, waste plastics, waste paper, broken glass, metal products, etc. In cities, due to the increasing population, domestic garbage is increasing at the rate of 10% every year, which constitutes a major public hazard. The serious harm of garbage, first of all, occupies a lot of land. The second is to pollute farmland. The third is to pollute groundwater. The fourth is to pollute the atmosphere. worker

What harm does garbage do to the environment?

Now there are more and more domestic garbage, and the air quality is getting worse and worse. What are the hazards of domestic garbage to the environment? PChouse, let's take a look. 1. The vicious accumulation of urban domestic waste occupying land has become a worldwide environmental disaster. According to the survey, among the 668 cities in China, at least 200 cities are surrounded by garbage, and the amount of garbage accumulated around the cities has reached 6* 109t over the years, covering an area of 5* 10 square meter. 2. Small solid wastes that pollute the atmosphere will fly with the wind, which will aggravate air pollution. The site where a large amount of garbage is piled up in the open air stinks, rats are infested, mosquitoes and flies breed, and a large number of harmful gases such as ammonia and sulfide are released into the atmosphere, causing air pollution. 3. Contaminated soil, municipal solid waste and other solid wastes are piled up in the open air for a long time. Under the leaching and infiltration of surface runoff and rainwater, its harmful components migrate to the surrounding and deep soil through soil pores, destroying the structure and physical and chemical properties of soil, reducing the ability of soil to retain fertilizer and water, and then polluting plants growing in soil, and sometimes accumulating in plants, which is harmful to human health when stored and eaten. 4, affecting health, spreading diseases Domestic garbage contains a large number of microorganisms, which is a breeding ground for germs, viruses, pests and so on. Mosquitoes, flies, birds and mice move in garbage ponds and landfills, which will bring pathogens in garbage to other places and seriously endanger human health.

What harm will garbage bring to the earth?

1, Pollution to water environment: During stacking or landfill projects, a large number of acidic, alkaline and toxic substances are generated, and wastewater containing mercury, lead and cadmium discharged from domestic garbage seeps into surface water or groundwater, resulting in black odor of water, unavailability of shallow groundwater and deterioration of water quality. 60% of rivers in China are polluted by ammonia nitrogen, volatile phenol and permanganate, and fluoride seriously exceeds the standard, resulting in the loss of self-purification function of water bodies. 2. Pollution to the atmospheric environment in the garbage area. Due to incineration or long-term stacking, garbage rots and becomes moldy, releasing a large number of toxic gases such as stench and sulfur, and dust and fine particles flying with the wind, causing suspended particles of sulfur dioxide in the air to exceed the standard. Acid rain and dust pollution often occur. 3. Erosion of land According to statistics, China produces 3 billion tons of garbage every year, and about 20,000 square meters of cultivated land is forced to be used for stacking and storing garbage. Land degradation and desertification are very serious. More importantly, a large number of toxic substances such as plastic bags and scrap metal are directly buried or left in the soil, which is difficult to degrade, seriously corrodes the land, causes soil hardening and alkalization, reduces the ability of water and fertilizer conservation, and reduces crop production or even crops, affecting crop quality. Extended data garbage disposal: 1. Wet garbage (organic garbage) is processed into organic fertilizer or organic compound fertilizer in organic garbage processing and utilization plant for greening or agricultural fertilization. 2. Dry garbage (inorganic garbage) is further classified into recyclable components such as waste paper, waste plastic, waste glass and waste metal in the domestic garbage sorting center, and then recycled by the corresponding recycling plant. 3. Hazardous wastes are classified in hazardous waste classification treatment station. Recyclable materials are sent for recycling, and residues are burned or safely buried.
