Humanity on the move: Sebastião Salgado’s searing reportage of exiles, migrants, and refugees. It has been almost a generation since Sebastião Salgado first published Exodus but the story it tells, of fraught human movement around the globe, has changed little in 16 years. The push and pull factors may shift, the nexus of conflict relocates from Rwanda to Syria, but the people who leave their homes tell the same tale: deprivation, hardship, and glimmers of hope, plotted along a journey of great psychological, as well as physical, toil.
