Napoga is a 12-year-old girl in Ghana, Africa．It is hard for her family to get clean water．Every morning, she leaves home at 5：30 to get clean water for her family in a village far away．It takes her six hours to get enough clean water for daily cooking and drinking．She has no time to go to school or to play with her friends．Millions of people in the world are like Napoga．They can’t get enough clean water to keep healthy．

Water covers 70% of the earth’s surface．But most of that is sea water．We can’t use it for very many things．Fresh water covers only 1% of the earth’s surface．

You probably feel lucky that your life isn’t as hard as Napoga’s．But that doesn’t mean you don’t have to worry about water．We all face serious water problems．One of them is water pollution．All kinds of things from cars, factories, farms and homes make our rivers, lakes, and oceans dirty．Polluted water is very bad for people to drink．And dirty water is bad for fish, too．Now, 34% of all kinds of fish are dying out．

How do cars and factories make our water dirty? First, they pollute the air．Then, when it rains, the rain water comes down and makes our drinking water dirty．Dirty rain, called acid rain, is also bad for plants, animals and buildings．

Scientists say that in 30 years, over half of the people in the world won’t have enough clean water．We have to learn how to save more water for ourselves and our children．
