Abstract

Transforming global food systems is crucial for mitigating environmental degradation, reducing the global disease burden and protecting sentient individuals from harm. Despite overwhelming evidence linking animal‐sourced foods to ecological damage, resource depletion and public health challenges, gaps remain in promoting sustainable consumption. This urgency is compounded by the scientific recognition of animal sentience, which elevates animal use to a moral issue. This study combines empirical data from a survey of 500 respondents with a literature review to explore motivations and behaviours driving plant‐based eating. Key suggested interventions to foster a responsible food system include: (i) raising awareness of animal rights, (ii) disseminating nutritional and environmental knowledge, (iii) reforming agri‐food subsidies, (iv) promoting plant‐based food research, commercialisation and consumption and (v) fostering social inclusion and positive recognition of vegan identity. By addressing psychological, social and structural barriers to animal‐free diets, this study offers actionable strategies for advancing a sustainable future.
