Papyrus is a light but strong reed that grows well in shallow, fresh water. The plant stood at the center of the ancient Egyptian civilization. It was used as paper and the reed's shape inspired the fluted columns of ancient Greece. Most of the papyrus swamps gradually disappeared from Egypt and other parts of Africa. As VOA's Faiza Elmasry discovered, though, restoring the papyrus swamps could hold the key to solve many of today’s problems, from pollution to water wars. Faith Lapidus narrates.
