China attaches great importance to the environmental pollution caused by plastic waste. Since 2007, the general office of the State Council issued a notice on restricting the use of plastic shopping bags in production and sales. By July 2020, nine departments of the national development and Reform Commission jointly issued the notice on Solidly Promoting the treatment of plastic pollution. All sectors of the society have been reducing the use of plastic products and better protecting the ecological environment reach a consensus. However, in the specific scenes of life, some previous "plastic" habits still exist, such as paper straw affecting "the pleasure of drinking milk tea", plastic mulch using "familiar", non degradable plastic bags are cheap, easy to get and convenient, lazy to choose which plastic substitutes, etc., leading to the existence of disposable non degradable plastic products.

It has been nearly 15 years since plastic limit was defined in China. It is not smooth to review the road of plastic limit. Although plastic limit has achieved certain results, there is still a certain distance compared with the ideal plastic limit. Looking for the reasons why plastic restriction is not ideal, among which the habit of using plastic is an important reason. Generally speaking, the habit of using plastic dominates us and we have to use plastic. If we want to further promote plastic restriction, we must cut off the habit, get rid of the old habit, establish a new habit, and make plastic restriction a living habit.

We are used to plastic straws, which are economical and durable, and have no peculiar smell. When we use paper straws instead of plastic straws, there are some problems: first, the taste is not good, "hard to use! There is also a strange smell of wood, which affects the taste of the drink! " Second, it's not durable. "After soaking for an hour, it swells and softens. It feels like eating toilet paper.". Because of this, from the perspective of consumers, using substitutes does not bring substantial benefits, and it is difficult for consumers to make it a habit to replace plastic pipes with paper straws. We must improve the quality of paper straws according to the problem of consumer reaction, such as improving the paper straws scientifically to eliminate the problem of consumer reaction, or looking for other economic, durable and degradable materials such as bamboo tubes or recyclable materials without paper straws. As long as the service provided is similar to or higher than the original service, most consumers have no need to refuse, so they are used to new substitutes, and the plastic limit is a step forward.

Agricultural plastics have played an important role in promoting agricultural production. Without agricultural plastics, it is difficult for many vegetable greenhouses to exist. It is difficult for us to eat a variety of vegetables in the cold winter. If there is no plastic film, the output of our agricultural products will be affected to varying degrees, and even affect the income of farmers. Farmers have been used to the application of plastics, which is low cost and easy to operate. If we want to limit the use of agricultural plastics, we must find relevant substitutes, which can not be accepted by farmers only if the quality of the substitutes is not far behind that of agricultural plastics. Because the overall efficacy of the current substitutes is lower than that of agricultural plastics, there are some obstacles for farmers to use substitutes. It is necessary to develop recyclable, recyclable and biodegradable substitutes with low cost. Only in this way can farmers use substitutes more smoothly and reduce agricultural plastics become a habit.

Reducing plastic pollution is the need of ecological civilization construction, we must try our best to achieve this goal. However, it is difficult for plastic restriction to work by shouting, which requires real substitutes. Every citizen needs to further establish the concept of environmental protection. Reducing the use of plastics is a kind of support for environmental protection and an obligation of every citizen. We also need to gradually reduce the use of plastic into a habit, develop the choice of appropriate alternatives and do not use plastic disposable tableware and other consumer habits, habits into nature, will have an important positive impact on the plastic limit.

Plastic restriction is good for the country, the people and ourselves. We have to strengthen our confidence, continue to push forward, and develop good substitutes to make plastic restriction more smoothly.
