This introductory chapter provides a background of the 1930s Dust Bowl on the U.S. southern plains, where the ancient grasslands that protected the soil from prairie winds and rains and nourished regional species were destroyed within just a few decades, following the violent opening of the plains to white settlement and the global market in the 1800s. Under pressure from the vagaries of the world economy, settlers sheared the land to expand cash-crop agriculture and ranching. As major drought descended on the plains, winds and static electricity lifted the desiccated, exposed topsoil, forming dust storms on an unprecedented scale. Such massive loss of soil and continued dry conditions meant the land could no longer support life as it once had. By the end of the 1930s, tens of thousands of people were displaced. Hence, when scientists today predict the increasing possibility of Dust Bowl-like conditions, they are signaling a particular kind of extreme ecological and social change.
