Mountains, meridians, rivers and borders; these are some of the features that carve up the world on our maps and in our minds. But geography is far less set in stone than we might believe and, over time, we have become experts at reshaping our surroundings. From the Qhapaq Ñan, South America's 'Great Road', and the Panama Canal to Mozambique's railways and Korea's sacred Baekdu-daegan mountain range, Samson explores how we mould the world around us.

And how, as we etch our needs onto the natural landscape, we alter the course of history. An immense work of cultural geography touching on ecology, sociology, history and politics, Earth Shapers argues that, far from being constrained by geography, we are instead its creators.
