Jan Zalasiewicz presents the scientific data that all too clearly shows our current trajectory towards an inhospitable planet. From atmospheric carbon dioxide and new minerals to microplastics and intelligent machines, our planet’s ecosystems are under ever increasing pressure. Presenting the mounting evidence of the Anthropocene as a proposed geological epoch while illustrating the urgency of our predicament, Zalasiewicz acknowledges the limitations of the natural sciences in grasping the complex processes driving these changes.
