October 16is World Food Day．The UN started the day in 1979．Itis used to remind people not to waste food and fight hunger（饥饿）．

Food shortage（匮乏）is a big problem around the world．Right now，there are more than 1billion（10亿）hungry people in the world．Many children go to sleep with hunger， and 15million of them die because of hunger each year．

There are several reasons why there are food shortages．First，therehave been more droughts（干旱） and floods（洪涝）recently．This，is badfor farmers and hurts their ability to grow food．Also，a growing population makes it more difficult to feed everyone．

Another big reason is food waste．Most people don't realize howmuch food they throw away every day．Sometimes we cook too much，orwe don't use it before it goes bad．The average（平均的）person throws  away 50kg of food every year，More than one third of all food producedgoes to waste around the world each year，sccording to the UN．That is3billion tons of food being wasted．

If the wasted food was saved，it could feed lots of people．Theamount of food wasted in Europe could feed 200million people，and thefood wasted in Latin America（拉丁美洲）could feed 300million people．

As teenagers，we should think twice next time we want to throwaway extra（额外的）food on our own plate．By cutting down on foodwaste，we could also help put food on the empty plates of some hungrychildren．
