'In this lucid introduction to global justice, Chris Armstrong shows how globalization concerns all of us. He explains why global justice matters and how to respond to it with both individual and collective initiatives.' Lea Ypi, London School of Economics 'Chris Armstrong's book is a terrific achievement. It successfully combines philosophical and ethical reasoning with a sure grasp of empirical realities. It discusses some of the most important issues of our time; and it does so in a wonderfully clear and accessible way that vividly conveys just what is at stake.'Simon Caney, University of Warwick
