If Australia's population is to almost double by 2050, we face challenges of extraordinary dimensions - economic, social and environmental. Coping with this growth demands visionary planning and insights from the rich history of immigration. Griffith REVIEW 29- Prosper or Perish investigates ways to find a balance between growth, diversity and sustainability in a shrinking world. A lead essay by journalist Peter Mares explores the tensions between humanitarian and environmental approachs to migration and population. He examines the emergence of an anti-growth movement and evaluates how we measure economic growth and quality of life. The pressure of how to strike the right balance between environmental preservation, cultural diversity and a robust economy will make population and immigration policies a significant factor in the federal election. Prosper or Perish explores what's at stake in getting the mix right, and reports on the realities for a new generation of global citizens whose work, lives and relationships stretch across borders and blend traditional identities. It includes moving memoirs, reportage from the front line and insightful analysis of the competing perspectives.
