What are the dangers of littering to the environment?

1. In the piling or landfill project, a large amount of acidic, alkaline, toxic substances, and garbage discharged from life contain mercury, lead, cadmium and other wastewater, which infiltrate into surface water or groundwater and cause black and odorous water bodies, and the shallow groundwater cannot be used and the water quality deteriorates.

2. Pollution of the atmospheric environment In the garbage area, due to incineration or long-term stacking, the garbage rots and mildew, releasing a large number of toxic gases such as foul odor and sulfur, and dust and fine particles fly with the wind, resulting in excessive sulfur dioxide suspended particulate matter in the air. Acid rain phenomenon and dust pollution occur frequently.

3. Erosion of land, land degradation, and desertification are very serious. Moreover, due to a large number of plastic bags, scrap metal and other toxic substances directly landfilled or left in the soil, it is difficult to degrade and seriously corrode the land, resulting in soil hardening, alkalinization, water and fertilizer retention capacity, crop yield reduction, and even extinction, affecting crop quality.

Water bodies in polluted areas. Some garbage carries a large number of pathogens.

Littering will cause these garbage to produce a large amount of pollutants and some heavy metal elements in the process of decay.

It will form organic matter, which will cause serious pollution of surface water and groundwater after being washed into rivers by rainwater, and microorganisms in water bodies will multiply in large numbers, and organisms in rivers and lakes will die in large numbers.

2. Make germs spread rapidly. There are many pathogenic microorganisms in garbage, and it is easy to be infected by mosquitoes, flies, cockroaches and rats after littering, which will endanger the health of people in nearby areas.

3. Polluting the atmosphere and damaging the living environment of the city. Some littered garbage is piled up in the open air, which will produce a large amount of ammonia, sulfur and other chemicals, discharge a large number of harmful gases, and erode the ozone layer in the atmosphere.

Make the nearby space have a foul smell and affect people's lives.

4. Polluting the land environment and littering will degrade the nearby environment and make desertification more serious. Some toxic substances such as plastic bags and scrap metal are directly landfilled or left in the soil, which is difficult to degrade, which will harden the nearby soil, reduce the ability to alkalize water and fertilizer retention, reduce productivity, and affect the quality of crops.

The hazards of littering are: polluting land, polluting water, polluting air, and being inconvenient to clean.

1. Polluting the land.

Many people litter plastic bags, paper, and peels in the land, which not only hinders the appearance but also pollutes the land, and the degradation of plastic in the land is extremely slow. In particular, do not litter batteries, batteries contain heavy metals, one button battery can pollute 600,000 liters of water, which is equal to the amount of water a person drinks in a lifetime. How terrible is that a battery rotting in the ground can make one square meter of land lose its use value!

2. Polluting water bodies.

Littering garbage in rivers and seas, the chemicals in the garbage can pollute the water body, and even breed some bacteria, or cause algae to bloom and affect the animals in the water. The garbage in the sea is eaten as food by some fish and turtles, leaving these fish deformed and miserable for life.

3. Polluting the air.

Oxygen and sunlight in the natural environment are natural catalysts, and garbage is exposed to the air, causing chemical reactions, producing foul odors and even toxic gases, making the air polluted.

4. It is not easy to clean.

Littering also increases the workload of cleaners, resulting in the consumption of human resources. Originally, the work of garbage classification in China is not good enough, and littering makes garbage cleaning more difficult.

The hazards of littering are as follows:

1. Polluting the air.

Garbage is a mixture of complex compositions. In the process of transportation and open stacking, the decomposition of organic matter produces foul odor, and releases a large number of ammonia, sulfide and other pollutants to the atmosphere, including more than 100 kinds of organic volatile gases, which contain many carcinogenic and teratogenic substances. Plastic film, paper scraps and dust are blown by the wind to form "white pollution".

2. Polluting water bodies.

The harmful components in the garbage are easy to be washed into the surface water body by rainwater, and a large number of acidic and alkaline organic pollutants will be produced in the process of garbage stacking or filling pits, and the heavy metals in the garbage will be dissolved at the same time. Waste is disposed of directly into rivers, lakes or oceans, causing even more pollution.

3. Fire hazards.

Garbage contains a large amount of combustibles, and methane and other combustible gases will be produced in the process of natural stacking, which is easy to cause disasters and garbage accidents in case of open flames or spontaneous combustion, causing heavy losses.

4. Infectious diseases.

Garbage not only contains pathogenic microorganisms, but also provides food, habitat and breeding places for rats, birds, mosquitoes and flies, and is also a source of infectious diseases.

5. Occupy too much space.

General household waste can be divided into five categories: waste paper, plastic, glass, metal and biological waste. There are many main harms of garbage to human life and the environment, first of all, it occupies too much land.
