Water is life. Humans can survive without food for about 3 weeks but only 3 days without water. That's because the human body is 60% water. In Africa, people suffer to get the water they need for everyday life. During the process, they go through many horrors. Imagine you are a head of a family in one of these places. You have to provide for your family the essence of life which is water. You go through a lot of troubles just to get the water they need. Even though you are just simulating, think of this game as many people's lives. They live these horrors daily. They can suffer extreme consequences for every single decision they make, you make, so choose wisely. You have limited resources, so make the best use out of them.
Remember, this issue is just one of many these people live.
