What harm does plastic products do to people?
Plastic bags really bring convenience to our life, but this temporary convenience brings long-term harm
The recycling of plastic bags is of low value. In addition, there are potential hazards in the course of use, except for the pollution caused by visual pollution in urban streets, tourist areas, water bodies, highways and railways. Plastic structure is stable, not easy to be degraded by natural microorganisms, and not separated in the natural environment for a long time. This means that if plastic waste is not recycled, it will become a permanent pollutant in the environment and will continue to accumulate. It will cause great harm to the environment.
Great harm to the land, change its pH, affecting crops to absorb nutrients and water, resulting in farmersAs for the abandonment of plastic products in water or land, it not only affects the environment, but also causes death if swallowed passively. This undermines the ecological balance.Fourth, the high temperature decomposes the poisonous material, the plastic product has no poisonous substance, but because of its recoveryThe equipment used is not perfect, the process is simple and crude, and many manufacturers do not have legitimate business license, resulting in reproductionWhen the temperature reaches 65 degrees centigrade, the toxic substances will precipitate and seep into the food, which will cause serious harm to the vital parts of the liver, kidneys, reproductive system and central nervous system."White pollution" mainly refers to the two negative effects of "visual pollution" and "potential harm" to the environmentEffect。
First, it affects the development of agriculture. Waste plastic products are constantly accumulated in the soil, which will affect the absorption of nutrients and water, resulting in crop failure.Second, it poses a threat to animal survival. Abandoned plastic waste on land or in water; swallowed by animals as food and killed animals. Last year, there were 20 herdsmen on the lakeside of Qinghai. Nearly 1000 sheep were killed, and the economic loss was about about 300000 yuan. Love the sheep eat oily residue in a plastic bag wrapped folder, but often even plastic bags to eat it, because the plastic food for a long time under the retention in the stomach to digest, the stomach was filled with sheep, can not eat, can only be finally starved to death. Such things are common in zoos, in pastoral areas, in rural areas, and in the ocean.Third, waste plastics will not only take up a large amount of land, but also be occupied by the land for a long time to recover, and affect the sustainable use of land. Into the domestic waste of waste plastic products, if its landfill, 200 years without degradation.
