As Lake Chad vanishes, seven million people are on the brink of starvation.
Not so long ago, Lake Chad was one of the largest bodies of water in Africa. The thick reeds and vital wetlands around its basin provided vast freshwater reserves, breeding grounds for fish, fertile soil for agriculture, and grasslands where farmers grazed their animals. In 1963, it spanned almost 10,000 square miles, an expanse roughly the size of Maryland. But as climate change has taken its toll, the lake has shrunk by 90 percent. Today, only 965 square miles remain. Wetlands have given way to sand dunes. Farmers have abandoned their fields. Those who still live by the lake struggle to survive, beset by chronic drought and the slow onset of ecological catastrophe.
