Instead, they divide the world up into "anthromes." There is an "urban" anthrome that stretches over five hundred thousand square miles, an "irrigated cropland" anthrome (a million square miles), and a "populated forest" (four and a half million square miles). Ellis and Ramankutty count a total of eighteen "anthromes," which together extend over thirty-nine million square miles.
