Roshdy Ebrahim invites readers to reconsider how life is organized globally by viewing the planet as a human body. The skeleton consists of transportation infrastructure—roads, railways, bridges, tunnels, and air and seaports—that enable movement across continents. The vascular system comprises oil and gas pipelines and electricity grids that distribute energy. The nervous system is made up of Internet cables, satellites, cellular networks, and data centers that facilitate information sharing. Approximately half the world's population lives in cities, which generate four-fifths of global GDP and serve as the world's economic engines. Over 2,100 cities have populations of 250,000 or more, with an increasing number of mega-cities and networked urban areas called conurbations, some with at least 10 million residents.
