Abstract: This article situates itself within the context of the ecological crisis of the Anthropocene and engages in theoretical reflection on the Western ecocritical theory’s neglect of the critical potential of science fiction literature. This study focuses on representative texts such as The Waste Tide, The Three-Body Problem, and The Windup Girl, and reveals that science fiction plays a unique and central role in toxic writing and slow violence narratives. Through toxic turn, science fiction reveals the duality of the ecological crisis under techno-capitalism: toxic substances are both sources of destruction and potential agents of remediation. Furthermore, by exploring “imperfect symbiote,” science fiction shifts the ethical focus from “saving nature” to “coexisting with toxicity,” offering new practical pathways for posthuman ethics. This paper argues that science fiction should be regarded as a vital supplement to ecocriticism. Its toxic narratives provide ecocriticism with a more pragmatically significant theoretical perspective across multiple dimensions: the global and the local, nature and technology, and the body and the environment. Through the exploration of toxic writing and symbiotic ethics, science fiction offers new cultural resources and ethical possibilities for addressing the ecological crises of the Anthropocene.
