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 (占据) 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.
