At latest count, 244 million people--the highest number in history--reside in a nation in which they were not born. But migration is not a new phenomenon. Elizabeth Colliers and Charles Strain's Global Migration: What's Happening, Why, and a Just Response unpacks the complex issues surrounding modern migration. Using the See, Judge, Act method of reflection and action, this text goes beyond facts and statistics, offering personal narratives, principles for critical thinking drawn from Catholic social teaching, and opportunities for action from the individual to the international level. Focused on the humanitarian work of Catholic Relief Services throughout the world, Global Migration inspires reflection, provokes discussion, and empowers students to respond to today's greatest humanitarian crisis.
