Do you think that living a hungry life is last century's story? Well, it may be this century's headline. The world has growing worries about a global food shortage. Right now, there are about 805 million hungry people in the world, according to a survey of the Food and Agriculture Organization of the UN. Children can't escape this either. Around 15 million children die of hunger each year. What causes food shortage? There are several reasons.
There are now more droughts and floods. This is very harmful to farmers.
Besides, with the growing population，feeding everyone is more difficult. There are a little more than 7 billion people in the world now. By 2050，the world's population will be more than 9 billion.
Another reason is food waste. A person throws away about 50kg of food every year on average. How can we help with food shortage? The easiest way is to cut down on food waste. Next time before throwing away the food on your plate, just think about how much work has been done to make it. By buying less, we waste less. This takes the pressure off producing so much food. And it helps to solve the problem of food shortage. You can also ask your schoolmates to join you.
Researchers at Kansas State University in the US put up short anti-waste slogans(标语)“Think Before You Waste" in dining rooms. Guess what happened? Students wasted fifteen percent less food after that! The author of the study said, “You don't need a huge activity to make a difference. ”
