科学实验活动册系列答案
Oct.16 is World Food Day. The UN started the day in 1979. It’s used to remind people not to waste food and fight hunger.
A big number of people in the world still don’t have enough food to eat. Food shortage（匮乏）is a big problem worldwide. Right now, there are more than 1,000 million hungry people in the world according to the UN. Many children go to sleep hungry, and 15 million of them die of hunger each year.
There are several reasons why there are food shortages. First, there have been more droughts（干旱）and floods recently. Also, a growing population makes feeding everyone more difficult.
Another big reason is food waste. Most people don’t realize how much food they throw away every day. Sometimes we cook too much, or we don’t use it before it goes bad. The average（平均的）person throws away 50 kg of food every year. According to the UN, more than one third of all food produced worldwide goes to waste each year.
That is over1, 300, 000 million kilograms of food being wasted. The amount of food wasted in Europe can feed 200 million people, and the food wasted in Latin America can feed 300 million a year.
So think twice next time you want to throw away food. By cutting down on food waste, we could help put food on the empty plates of some hungry children. Only order as much food as you can eat in a restaurant. If you can’t eat all you order, take the rest home. Don’t be too picky about food so that you don’t leave any on your plate. Some food may not taste great, but your body needs it. Keep an eye on what food you have at home. Don’t buy too much. Don’t cook too much.
When you throw away food, you are not just wasting the food itself. Resources（资源）are also wasted while growing, transporting and cooking the food. These things all take energy, time and water.
