Clearly, clean water is incredibly important. It prevents diarrheal disease, as an example. Undernutrition, malnutrition, is an underlying factor in many diseases and across the range, including pneumonia, but also HIV/AIDS, etc. It has a negative impact, obviously, across the board. Clearly, addressing undernutrition is important, and providing clean water and sanitation is important, if you're going to not only reduce these numbers but reduce them in a sustainable way moving forward.
