Feral Atlas invites you to explore the ecological worlds created when nonhuman entities become tangled up with human infrastructure projects. Seventy-nine field reports from scientists, humanists, and artists show you how to recognize “feral” ecologies, that is, ecologies that have been encouraged by human-built infrastructures, but which have developed and spread beyond human control. These infrastructural effects, Feral Atlas argues, are the Anthropocene. Playful, political, and insistently attuned to more-than-human histories, Feral Atlas does more than catalog sites of imperial and industrial ruin. Stretching conventional notions of maps and mapping, it draws on the relational potential of the digital to offer new ways of analyzing—and apprehending—the Anthropocene; while acknowledging danger, it demonstrates how in situ observation and transdisciplinary collaboration can cultivate vital forms of recognition and response to the urgent environmental challenges of our times.
