Silhouetted by salmon skies at sunset, a pair of waterfowl alights on a tree limb near the Zambezi River. Often called the lifeline of southern Africa, the Zambezi cuts a 2,200-mile (3,540-kilometer) course east from Zambia to the Indian Ocean, sustaining elephants, hippos, crocodiles, hundreds of species of birds—and tens of millions of people—along the way.
