The harm of plastic to the environment
The World’s Plastic pollution Crisis explained.
Waste management is an important issue because of the harm its inefficiency can cause to the environment. Not only can improper waste management be a danger to the environment, but it can also lead to waterborne diseases, which is extremely dangerous.
Plastics are widely used around the world due to ease of manufacturing, low cost, stable chemical properties, and good water resistance, the production has been steadily increasing year by year. The commonly used plastics include polystyrene, nylon, polyurethane, polypropylene, etc. these plastics are gradually decompose by the physical, chemical and biological effects in the environment, plastics are easily fragmented under the effect of environmental forces, however, it takes about a long time for these plastics to be completely decomposed.
First, affect agricultural development. Waste plastic products are continuously accumulated in the soil, which will affect the absorption of nutrients and water by crops, leading to crop yield reduction.
Second, it poses a threat to the survival of animals. Waste plastic products abandoned on land or in water bodies are swallowed by animals as food, causing animals to die.
Third, waste plastics will not only occupy a large amount of land with landfills, but also the occupied land will not be restored for a long time, affecting the sustainable use of land. If the waste plastic products entering the domestic garbage are buried, they will not be degraded for 200 years.
04.Fourth, harm to people's health:
1. It seriously affects our health. When the temperature reaches 65 , harmful substances in disposable foam plastic tableware will penetrate into food, causing damage to human liver, kidney and central nervous system.
2. The main materials of plastic bags used in daily life are polyethylene and polyvinyl chloride. When people contact vinyl chloride, they will have swollen wrists and fingers, skin sclerosis and other symptoms, and may also have splenomegaly, liver damage and other symptoms.
3. If buried underground, it will rot for about 200 years, which will have a negative impact on the soil pH, worsen the soil environment, and seriously affect the growth of crops.
