This study examines the relationship between women, the female body, and nature in Han Kang’s The Vegetarian through an ecofeminist perspective. It focuses on the protagonist Yeong-hye’s rejection of meat consumption, her resistance to patriarchal expectations, and her gradual identification with plant life. The study employs a qualitative descriptive method and ecofeminist literary criticism, drawing on the theoretical perspectives of Maria Mies and Vandana Shiva, Val Plumwood, and Carol J. Adams. The primary data are selected passages, dialogues, descriptions, and narrative events from the three sections of the novel: “The Vegetarian,” “Mongolian Mark,” and “Flaming Trees.” The findings reveal three interconnected dimensions. First, Yeong-hye’s body becomes a site of patriarchal control, as her husband and family attempt to regulate her choices and bodily autonomy. Second, her rejection of meat challenges the normalization of violence against animals and exposes the relationship between the consumption of animal bodies and the objectification of women. Third, her identification with plants represents an attempt to imagine an alternative relationship with the natural world beyond domination and exploitation. However, this transformation is deeply ambivalent because her rejection of human practices also leads to physical deterioration and increasing isolation. The study argues that The Vegetarian presents ecofeminist resistance as a complex process that questions patriarchal and anthropocentric domination while revealing the limitations and dangers of escaping oppressive social structures through bodily self-denial.
