Madagascar is a country located off the southeastern coast of Africa. It's the fourth largest island in the world. The animated film of the same name doesn't tell you that most schools in Madagascar don't have running water. Children get ill all the time because of poor sanitation. When they get sick, they can't attend school. Then they don't do well in school.
There is a big initiative now to provide enough materials to enable children to wash their hands at least once a day. How many times a day do you get to wash your hands? Imagine not having the water to wash them even once.
