Plastic bags do bring a lot of convenience to people’s life, but at the same time, it also brings long-term harms. The recycling value of plastic bags is very low. When the waste plastic bags scatter on city streets, tourism zone, in the water, or long the roads and railways, it will cause “visual pollution”. What’s worse, it will also cause some potential hazards.
First of all, plastic bags affect agricultural development.
When the waste plastic products mix in the soil and accumulate continuously, they will affect the absorption of nutrients and water by the crops, thus reducing the output of the crops.
Secondly, plastic bags threaten the survival of animals.
If animals mistakenly take the waste of plastic products as food and swallow them, it will lead to animal death. Last year, there were nearly one thousand sheep in Qinghai Lake died because of this, which caused economic loss of about 300 thousand Yuan. Sheep like to eat the oily residues wrapped in the plastic bags, while plastic is difficult to be digested. If it remains in the stomach for a long time, there will be no room in stomach for other foods. As a result, these sheep can only be starved to death at last. Such a thing is very common in the zoo, pasturing area, village, and the ocean.
Thirdly, waste plastics are difficult to be disposed.
The waste plastics not only takes up a lot of land, but the land occupied will not recover for a long time, which will affect the sustainable use of the land. If the waste plastic products are buried in the ground, it will take 200 years for the degradation. What’s more, the raw material of plastic bags is petroleum, which not only consumes a lot of resources, but also can not be broken down. If it is buried in the ground, it will pollute the land and river.
In addition, the plastic itself will release harmful gases. Especially cooked foods, if they are packaged in plastic bags, they often degenerate very easily. The effect of deteriorated foods is particularly prominent on the health and development of children.
Last but not the least, the production of plastic bags will consume a large number of energy, such as polyethylene (PE), polrvinyl chloride (PVC), shrinkfilm and Low-Density Polyethylene (LDPE). As a result, in order to change this situation, the replacement of plastic with other recycling and degradable materials is extremely urgent.
