Charles C. Mann writes narrative non-fiction about the Americas, environment, technology and the large systems created by human societies. 1491 argues that the Western Hemisphere before Columbus contained more populous, technologically complex and environmentally managed societies than older popular accounts often suggested. 1493 follows the global ecological and economic consequences of contact, tracing the movement of crops, diseases, animals, silver and people across continents after Columbus. The Wizard and the Prophet shifts to the modern environmental debate through Norman Borlaug and William Vogt, using their contrasting ideas to frame disputes over population, agriculture and resource use. Mann's books are broad, research-heavy and written for general readers, with a strong interest in correcting simplified historical narratives. 1491 is the clearest entry for pre-Columbian history, while 1493 is more global and focused on exchange, ecology and the creation of an interconnected world.
