Barry Lopez's 'Horizon' is a profound exploration of humanity's restless spirit of exploration, as experienced and reflected upon by the National Book Award-winning author. The narrative is a weave of personal journeys, spanning from the forests of Western Oregon to the chilling expanses of Antarctica. Each locale offers a backdrop to a broader examination of human history, from prehistoric migrations to contemporary eco-tourism. As Lopez journeys to the High Arctic, the Galapagos, the Kenyan desert, Botany Bay, and beyond, he contemplates the impact of colonialism, the enlightenment era, and our collective responsibility to the planet. Throughout these travels, Lopez anchors his observations in a deep sense of environmental and philosophical inquiry, searching for a semblance of meaning in an increasingly fragmented world.
