In China, a lot of food is wasted every year and the waste food is enough for people. The food is wasted in restaurants, at home and in schools, etc. In restaurants or at home, people often order or cook food. But they can’t eat it up。When they go out of a restaurant, full and happy, they never look back the uncertain food on the table again. Should Chinese consumers (消费者) feel for the terrible waste? In schools, we can often see a lot of students food away after meals and they only eat the food they like. Everyone is supposed to have enough food to eat. However, in some places, the food is so little a lot of people died from hunger. Although China has tried hard to solve of hunger over the past thirty years, the job is not finished yet. Food is important to us all. We live without food. So is necessary for us to love food and try to eat up everything on our plates. When we eat in restaurants, we should pack up the leftovers(剩菜剩饭). We also need to tell other people to stop food as soon as possible.
