What should be done in the canteens of colleges and universities to prevent students from wasting food?

In the canteens of colleges and universities, I think the school should pay more attention to the phenomenon of students wasting food, and don't ignore it. Because wasting food is not a trivial matter. Many people have no idea about food and waste food, so when cooking, they get into the habit of cooking a lot of vegetables and rice. So in view of this situation, I think schools should vigorously advocate saving food and instill such ideas in students, and it is best to post slogans like saving food in the canteen, so that everyone can always see these slogans. Seeing these slogans is tantamount to reminding themselves not to waste food.

? Then there is another way to help the aunts and uncles who cook vegetables in the school cafeteria. That is, the canteen should also re-set the price of buying a meal, that is, to buy half a meal and one meal, because many schools also have no habit of buying half a meal, so this leads to the situation that many students throw away their meals, because they can't eat them after buying them, which leads to these situations. Then schools can completely introduce this method, that is, they can buy half a meal, which can avoid the situation that many people throw out all their meals because they can't eat them.

? Because it is not easy to grow food bit by bit, as college students, we should learn to respect other people's labor achievements and form a good habit of saving food, because many poor places also have no food to eat, so we are very happy, so we should cherish today's happiness.

? Therefore, to sum up, I think schools should pay more attention to the phenomenon of students wasting food in canteens of colleges and universities, and don't ignore this matter.
