Africa, the Human Footprint
Shaping the land to serve human needs is a cornerstone of civilization. During the past century, humanity's footprint on the planet has spread faster than at any other time in history. To illustrate the relationship between people and the Earth, scientists from the Wildlife Conservation Society and the Earth Institute at Columbia University have created the Human Footprint map. Published in September 2005 as half of a two–map set with "Africa: A Storied Landscape."
