Have you ever thrown away a bottle of water? Maybe a bottle of water does not seem like much to you, but it can save the day for people who live in drought-hit* areas in China.

In the past few months, some places in southeast China has experienced a serious drought. In Yunnan, Guangxi, Sichuan, Guizhou and Chongqing, there has been very little rain since last autumn. Crops have died. The land has cracked* and wells and rivers have dried up. More than 20 million people are having difficulty finding safe drinking water.

After learning about the drought, many people across the country have helped by giving water, money and other resources*.

Last week, China asked every member of the Communist Youth League and Young Pioneers to give one bottle of water to the drought-hit areas. Students in primary schools and middle schools quickly joined in the activity. “A bottle of water isn’t much, but thousands of bottles will be of great use.” One student said. Some students offer their pocket money to the people there.  Other students also wrote their best wishes on the bottles.

The serious drought has also made students realize that saving water is very important. Some students decided to take a shower twice a week instead of every day, so that they can save a little water. Some students said they would never forget to turn off the water taps after using. Some students even went on the street to tell people to take part in water-saving activities.

Actually, learning how to save water is not difficult, and it can begin with teaching good habits to others around you. All you have to do is to think a little about how easy it is to waste water in everyday activities.
