15．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 still 870million hungry people in the world，according to a survey of the UN's Food and Agriculture Organization．Children can't escape this，either．Around fifteen million children die of hungry each year．
What's causing food shortages？There are several reasons．
There are now more droughts and floods．This is very harmful to farmers and their ability to grow food．
Besides，with the growing population，feeding everyone becomes more difficult．There are a little more than seven billion people in the world．By 2050，the world population will be more than nine billion．
Another reason is food waste．The average person throws away 50kg of food every year．
How can we help with food shortages？The easiest way is to cut down on food waste．
Next time before throwing away the food on your plate，just think 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．
In 2013，researchers at Kansas State University in the US put up short anti-waste slogans（标语） in dining rooms"Think Before You Waste"．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．"

Have you ever asked your relatives or friends if there is Wi-Fi in their houses？Have you ever
searched for Wi-Fi when you are at restaurants or hotels？The answers will probably be"Yes"．Most of us want Wi-Fi everywhere as if we can't live without it．But we can only use free Wi-Fi in some public places．We still have to spend some money accessing（连接）the Internet at most time．Here comes a piece of good news．
A rich，powerful organization in the USA called the Media Development Investment Fund （MDIF） has decided to change the age of online computing （计算） completely by giving free Wi-Fi to every person on Earth．They will send up hundreds of satellites into low Earth orbit（轨道）in 2015．
This is because they have made a survey and found that only 60% of the world's population have been able to get information on the Internet．And this is also because many countries are unable to offer people the necessary infrastructure（基础设施）to access the web．
We can expect to use free Wi-Fi everywhere in the near future．
