Ngongongare, a very poor village in Tanzania, needs water. And 10-year-old Eva Henderson of Tuscaloosa, Alabama, aims to do something about it! Their closest water source is polluted with chemicals, so they must walk 7 miles roundtrip to another source—a stream, used by both people and animals, that is also unsafe—that frequently causes diarrhea, parasites, cholera, typhoid…and death. Although the villagers must work hard in the fields just to survive, they commonly miss work due to illness. Children miss school because, when not sick, they and their moms must spend hours fetching water each day for drinking and cooking. “Water is their greatest need,” our contact there told me.
