Ben Rawlence has written for publications including the Guardian, London Review of Books, New York Times, New York Times Book Review and the New Yorker. While working for Human Rights Watch in the Horn of Africa he became fascinated by the Dadaab refugee camp, which became the subject of his acclaimed 2016 book, City of Thorns. His new book, THE TREELINE, is a powerful and beautifully written blend of reportage, nature, travel and science writing. Telling the story of our changing climate through six species of tree, it documents the devastating effects of human activity – and offers reasons for hope.
