Ben Rawlence is a British writer whose recent book, The Treeline, recounts his tour of the world around the Arctic circle, as he visited indigenous people living in all the northernmost countries. Their lives are being affected adversely by global warming, which is allowing trees to grow farther in the north than before. Different countries are forested with different predominant species, but the effects are generally negative, for the trees exacerbate the warming. Even caribou cannot survive in some of their former habitat. Rawlence has created a college in England that offers programs on topics relating to the environment and climate.
