Why do people fight for water?

For us, water coming out of the tap is a fact that we take for granted, but for many people across the world it is an absolute rare commodity. A large part of mankind does not have access to clean drinking water. This is a good reason to fight for water. In many areas of Africa, especially the dry areas of northern Africa, lack of rainfall can lead to a famine which leads to water hoarding. Although scientists predict that in future water will become one of the most hard-fought resources, the fight for water has already started. Many countries across the world are constantly at loggerheads regarding the right to water of a river flowing across the border.
