Nowadays, wasting food in school canteens is a common phenomenon. Wasted food pollutes our environment, so we can't protect the environment any more. Besides, wasting food is immoral. Every day, thousands of people die of hunger. We are lucky to have food, but we waste food that could have saved people's lives. I noticed that this problem is really difficult to solve. So, I'm here to give some suggestions to the canteen of our school. When we finish eating, we should ask the staff to check our plates. If we don't eat much, students will be punished in some way. Or, we can limit how students buy their food. For example, a student should not buy five kinds of desserts in one day. By adopting the two methods I gave above, I believe that our food waste problem will be solved.

I wrote it myself. . . . By the way, how old are you?
