The environmental emergency is the greatest threat we face. Preventing it will require an unprecedented political and social response. And yet, there is still hope.

Academic, physicist, environmental expert and award-winning science communicator Paul Behrens presents a radical dual analysis of a civilisation on the brink of catastrophe.

Setting out the pressing existential threats we face, he writes, in alternating chapters, of what the future could look like, at its most optimistic and pessimistic, and details the steps we can take to ensure our survival. In lucid and clear-sighted prose, Behrens argues that structural problems need structural solutions, and examines critical areas in which political will is necessary, including women's education, food and energy security, biodiversity and economics.
