Clean water is not only important for people to produce food,but necessary for our life. However,many people in Asia and Africa don't have enough clean water to use. The World Health Organization reports that almost 4 ,000 children die each day from dirty water or lack (缺乏) of water.

Farmers use 70% — 85% of the world fresh water to produce food. People usually don't pay much attention to how much water industry uses,but you may be surprised to know that industry uses 59% of the water in developed countries.

Home use takes up (占據(jù)) only 8% of the water in the world. But as cities grow,more water will be used. The local government has to try to make people use less water.

In 60% of European cities,people are saving water by using less. They even keep waste water for other use.

In Australia,the government has encouraged people to collect rainwater and recycle water from showers for a second use.

The US Environmental Protection Agency has made a water saving program to encourage families and businesses to check their water use and save more water. Scientists and the UN are looking for good water management as the key to solving the problem. We can all work together to protect our fresh water in our daily life.

It is easy for us to tell our friends from our enemies. But can animals do the same? Elephants can!They can use their eyes and noses to tell the differences between dangerous people and friendly people.

In Kenya,scientists found that elephants knew the different clothes of Maasai and Kamba people.Maasai men often kill animals for food,so they are dangerous to elephants. Kamba men are farmers and not a danger to elephants.

Last year,some animal scientists did an experiment. They found that elephants reacted (反應(yīng)) differently to smell and colon First,elephants were shown clothes of either a Maasai or a Kamba man. When the elephants smelt the clothes worn by a Maasai man,they moved away fast. When they smelt the clothes worn by Kamba men,they relaxed.

Then,the same elephants were shown red clothes. They got angry,because red is often worn by Maasai men. Instead of running away,the elephants rushed angrily to the red clothes. Why? If an elephant smells a danger,he thinks that the danger is close and the best thing to do is to run away and hide. If he sees a danger,he thinks the risk (危險(xiǎn)性) is low. So the elephant is a little braver and ready to fight.
