Napoga is a 12-year-old girl in Ghana (加纳), Africa. It is hard for her family to get clean water. Every morning, she leaves home at half past five to get clean water for her family in a village far away. She has no time to go to school or to play with her friends. Millions of people in the world are facing the problem of water shortage like Napoga. They can't get enough clean water to keep healthy.
Earth Day is April 22. The water we use is the most important natural resource (自然资源) on the earth. Water covers 70% of the earth's surface. Unfortunately, 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.
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. 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, more than 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.
