Salvador Rueda is the creator of a new type of urban planning, ecosystemic urban planning, and of a new urban cell, the superblock, the basis of a new model of mobility and public space and the basis of the model of any urban system. An ecologist and urban planner of international prestige, Rueda breaks down in this book of conversations with the writer Gabi Martínez an ideology based on incontestable data and argues that it is possible to inhabit the city without destroying the planet.
