The present environmental crisis is the gravest challenge of our time. And it is so because it is planetary. To say that it is planetary is not to say that ‘we are all in this together’ or that anthropogenic disturbances act as a welcome equaliser: inequities are still the currency of the day in a vastly unjust world. Rather, it is to say that it is no longer possible to delimit or suppress the consequences arising from events pertaining to one particular geographical area or to even predict the areas that will be affected by an uncontrollable and extreme climate that sometimes does not spare even the rich. It also means confronting the fact that the environmental transformations cur-rently on course are unprecedented in human history in terms of both the rapidity at which they are occurring and their global scope. Whether we like it or not, our world is an interconnected sphere made up of delicately interdependent ecosystems and lifeworlds. It urgently demands solutions on the planetary scale. This book hopes to contribute to this task by exploring how f ilm and related media have both shaped and responded to the history of our planetary consciousness.
