First, it affects the development of agriculture. Waste plastic bags are accumulated in the soil continuously, which will affect the absorption of nutrients and water by crops, leading to crop yield reduction.
Secondly, it poses a threat to the survival of animals. Plastic waste discarded on land or in water is eaten by animals as food, resulting in animal death. Last year, 20 herdsmen along the coast of Qinghai Lake lost nearly 1,000 sheep, causing economic losses of more than 300,000 yuan. Sheep like to eat oil residue wrapped in plastic bags, but often even plastic bags eat together, because plastic bags eat in the stomach for a long time can not digest, the stomach of these sheep is full, can not eat any more, and finally can only starve to death. Such things are common in zoos, pastures, villages and oceans.
Thirdly, plastic waste landfill will not only occupy a large amount of land, but also occupy land can not be restored for a long time, affecting the sustainable use of land. Waste plastic products entering domestic waste will not degrade within 200 years if buried.
It does great harm to the land, changes the pH value of the soil, affects the absorption of nutrients and water by crops, and leads to the development of agriculture.
For plastic products discarded in water or on land, they not only affect the environment, but also lead to death if swallowed passively. This destroys the ecological balance.
Fourth, high temperature decomposes toxic substances. Plastic products are not toxic substances, but because of their recycling.
The equipment used is not perfect, the process is simple, many manufacturers do not have a legal business license, resulting in reproduction.
When the temperature of plastic products reaches 65 C, toxic substances will be separated and permeated into food, causing harm to human liver, kidney, reproductive system, central nervous system and other important parts.
