Abstract
North American literature has a predilection for science fiction novels in the form of apocalyptic dystopias, depicting major ecological disasters, a predilection more marked than that of European literature, at least of French-speaking expression. What makes these novels anticipation the end of the World against a backdrop of ecological crisis is that they choose generic and stylistic hybridity to depict extreme situations, in the strong sense of the term, since the works studied in the context of this article it is, each time, humanity which risks disappearing. Ecological dystopias all feature environmental catastrophes, leading to the collapse of the world as we know it in the not-too-distant future. They then show them all as "possible" because they have taken place in the space-time of the fiction they have developed and whose dates are so many signals of an "irruption of the possible into the 'impossible.
