2. pollute the air. Plastics, scraps of paper and dust fly with the wind.
3. Polluted water. Plastic bottles and lunch boxes floating on the rivers and seas, plastic bags and bread paper hanging from branches above the water surface not only cause environmental pollution, but also endanger the health of animals by eating white garbage by mistake, and even starve to death due to indigestion in the digestive tract.
4. Fire hazard. Almost all white garbage is combustible, and combustible gases such as methane will be produced during natural stacking. Fire accidents easily caused by open flame or spontaneous combustion often occur, often causing heavy losses.
5. White garbage may become a nest of pests, which can provide food, shelter and breeding places for mice, birds and mosquitoes and flies, and the residue in it is often the root of infectious diseases.
6. Waste plastic packaging is difficult to degrade after entering the environment, resulting in long-term and deep-seated ecological and environmental problems. First of all, the mixing of waste plastic packaging materials into soil will affect the absorption of nutrients and water by crops, leading to crop yield reduction; Secondly, if livestock eat plastic film, it will cause digestive tract diseases and even death.
7. Because of its large volume, landfill will breed bacteria and pollute groundwater.
Extended data:
White pollution:
It mainly includes plastic bags, plastic packaging, disposable polypropylene snack boxes, plastic tableware cups and plates, electrical appliances filled with foaming fillers, plastic beverage bottles, yogurt cups, ice cream skins and so on.
Facing the increasingly serious problem of white pollution, people hope to find a plastic substitute that can replace the existing plastic properties without causing white pollution.
Degradable plastics came into being. The characteristic of this new functional plastic is that after reaching a certain service life, its chemical structure will degrade obviously under certain environmental conditions, which is harmless or less harmful to the natural environment.
For example, starch-filled plastics, first of all, the starch contained in it is rapidly decomposed by amylase secreted by microorganisms in the soil in a short time, which leads to the decline of the mechanical properties of the film. At the same time, the self-oxidant added in the formula reacts with the metal salt in the soil to generate peroxide, which breaks the chain of polyethylene and degrades it into small pieces that are easily swallowed by microorganisms, which are absorbed by the natural environment and improve the quality of soil.
