Shanghai has put a stop to food and beverage waste into social norms, which should be popularized. Caring for food and saving food are excellent traditional virtues and should be carried forward. We know that in recent years, after people's living standards have improved, the food and beverage industry is also very developed, and everyone generally likes to eat out in restaurants, which has caused great waste. Many foods have not been finished and have been wasted in vain, although most people in China are out of poverty. But there are still a few people who can't eat enough and wear warm clothes, especially in some foreign countries. Every year, many people die of hunger, so we should not waste food, and we should start with you and me to put an end to waste.

We know that the production of grain needs a complete production chain. First of all, it needs raw materials for food, which requires farmers to grow crops. After the crops are successfully planted, they are bought into factories and processed into various delicacies, and then cooked and decorated by chefs as food for sale. If waste can be eliminated, China's grain reserves will meet the needs of more people. Don't think that our country is no longer plagued by poverty. Our country has a large population, and the average grain reserve is far from meeting the needs of our people. Our country needs to import a large amount of food from abroad every year, so it is necessary for us to reduce food waste as much as possible and achieve domestic self-sufficiency.

Professor Yuan Longping cultivated hybrid rice hard to solve the problem that many people don't have enough to eat. China's resources are limited, and there is no place for us to waste. The wasted food has also caused great troubles to our life and production. The economic losses caused by food waste are huge every year, which we can avoid through our own actions, and we can reduce unnecessary waste and expenditure.

Shanghai's practice of putting a stop to food waste into social norms should be extended to all provinces and cities. As a big city with developed economy, Shanghai has a well-developed catering industry, which can be greatly reduced by bringing the suppression of catering waste into social norms.
