You come home on a hot summer day, hoping to have a cool bath, but find there is no water. Then you see how important water is in your daily life. While sometimes you have the idea in many parts of the world, water is not just about one's everyday needs.
In countries like Tanzania, water is hard to get, and the job of collecting water falls on women's shoulders. Girls often have to leave school to collect water, while their brothers stay at school studying. The girls spend more time collecting water. That means they have less time for learning.
For these girls, "Knowledge is Power" is not just words; it's a sad fact in real life. As they spend less time at school, they have fewer chances of getting good jobs, and they often have no choices on important matters, like who to marry. These girls are often married into poor families. They have little money or knowledge to take care of their children. For the baby girls who are lucky enough to survive (生存), their life may be still around "water", just like their mothers'.
