Should plastic bags be banned?

The use of plastic bags should be banned because they are very harmful;

First of all, it brings serious environmental problems. Plastic bags are mainly made of nitrocellulose. This substance is difficult to degrade naturally. Even if it is buried underground, it will take hundreds of years to completely rot, which seriously affects the permeability of the land and hinders the growth of vegetation.

Secondly, because plastic bags are widely used now, there is no place to put a lot of plastic garbage. Some people will throw plastic garbage into the sea, which will cause great pollution to the marine environment. Marine animals will be attracted by colorful plastic bags, and then killed by mistake and suffocated.

Thirdly, at present, the most common disposal method of waste plastic bags is incineration, and the harmful gas generated by incineration of plastic bags is very harmful to biology, which has caused serious secondary pollution.
