Up to a decade or two ago, the system production-nature (man's productive-exploitative relationship with nature and its resources) was perceived as a constant, whereas everybody was busy imagining different forms of the social organization of production and commerce (Fascism or Communism as alternatives to liberal capitalism); today, as Fredric Jameson perspicaciously remarked, nobody seriously considers possible alternatives to capitalism any longer, whereas popular imagination is persecuted by the visions of the forthcoming 'breakdown of nature', of the stoppage of all life on earth - it seems easier to imagine the 'end of the world' than a far more modest change in the mode of production, as if liberal capitalism is the 'real' that will somehow survive even under conditions of a global ecological catastrophe.
