1493 and the New World Columbus Created

Charles Mann explains how Christopher Columbus changed the world when he set foot in the Americas, setting off a series of vast ecological changes as European vessels carried thousands of species across the oceans. 1493: Uncovering the New World Columbus Created, is a new history of the Columbian Exchange, the reason there are tomatoes in Italy, oranges in Florida, chocolates in Switzerland, and chili peppers in Thailand, and explains how earthworms, mosquitoes, and cockroaches; honeybees, dandelions, and African grasses; bacteria, fungi, and viruses; and rats were moved across the globe, changing lives and landscapes.
