With the development of the society, the level of our life has improved. We have all kinds of food to choose from. However, we all waste food, you and me, every day, millions of tons of it. In China, plenty of food is wasted in restaurants every year to feed 200 million people. And the amount(数量) of food wasted by Chinese customers is increasing fast. So our country is being encouraged to stop wasting food. What should Chinese customers do to stop food waste?

◆Keep a kitchen diary.

All of us should keep a kitchen diary, and we can know how much food we waste at home.

The first thing for us to do is to stop throwing away food that we can still eat. We should eat everything we buy and if we cannot, we should buy less.

◆Buy only what we need.

We should ask for smaller ones in the supermarket. We should also check how much food we have before buying more. We shouldn't bring much food we don't need home even if large posters ask us to do so.

◆Develop the habit of saving food.

Chinese customers are generous(慷慨的) and friendly. In restaurants, often too much food is ordered and served. So when eating out, we are supposed to exclude(排除) the food in the menu if we don't plan to eat it. And order smaller servings in restaurants and take home what we cannot finish.

Don't put it off! Let's stop food waste today!
