The United Nations estimates that people in sub-Saharan Africa spend roughly 40 billion hours per year collecting water, and what they do find is often unsafe to drink. In some parts of Africa, finding potable water can be a six-hour endeavor. Roughly 3.4 million people die every year from water-related disease. The water shortage is a major life-threatening problem that affects as many as 1 billion people on the continent alone, but it's not as though you can just snap your fingers and make water magically appear out of thin air. Or can you?
