What harm do plastic bags bring to the environment?

First of all, it affects agricultural development. The accumulation of waste plastic products mixed in soil will affect the absorption of nutrients and water by crops, resulting in crop yield reduction.

Second, it poses a threat to the survival of animals. Waste plastic products discarded on land or in water are swallowed by animals as food, resulting in animal death. Last year, there were 20 herders near Qinghai Lake, nearly 1,000 sheep died and the economic loss was more than 300,000 yuan. Sheep like to eat oil residue wrapped in plastic bags, but they often eat together. Because the plastic they eat is difficult to digest in the stomach for a long time, the stomach is crowded, they can't eat any more, and finally they can only starve to death. Such things are common in zoos, pastoral areas, rural areas and oceans.

Third, waste plastics will not only occupy a lot of land with landfill, but also the occupied land will not be restored for a long time, which will affect the sustainable use of land. Waste plastic products entering domestic garbage will not degrade for 200 years if they are buried.

It is understood that the plastic bags we usually use have many hazards:

1, which seriously affects our health. When the temperature reaches 65℃, harmful substances in disposable foamed plastic tableware will penetrate into food, causing damage to human liver, kidney and central nervous system.

2. The main raw materials of daily plastic bags are polyethylene and polyvinyl chloride. When people are exposed to vinyl chloride, there will be symptoms such as wrist and finger edema and skin sclerosis, as well as splenomegaly and liver injury.

3. If it is buried underground, it will take about 200 years to decompose, which will adversely affect the pH of the soil, worsen the soil environment and seriously affect the growth of crops. If livestock eat plastic film, it will cause digestive tract diseases and even death.
