For more than a decade, Saraceno has been imagining a world free from borders and fossil fuels. In this age of climate emergency, his work has focused on a new era of our Earth that emphasizes the atmosphere, called the Aerocene. In keeping with Saraceno’s own concerns with reducing human impact on the environment, the book will be printed in part on wastepaper salvaged from other print jobs by Italian printing atelier Musumeci, in an effort to reduce the waste associated with the book’s production.
