This introductory chapter explores the relationship between food systems and the multifaceted injustices arising from environmental degradation. Drawing on Rob White’s eco-justice framework, the text uses his three interconnected dimensions: environmental (human-centred impacts), ecological (ecosystem-centred impacts), and species based (focusing on non-human life). The book is positioned as an extended thought experiment, imagining the cessation of specific food commodities and examining the resulting ripple effects through ethical, economic, and ecological lenses. It adopts a neutral stance, critically evaluating industrial food systems and their role in perpetuating inequities, biodiversity loss, and environmental harm. Key concepts like environmental justice emphasise the disproportionate burdens on marginalised communities, while ecological justice underscores the intrinsic rights of ecosystems. Species justice interrogates the welfare and sentience of non-human life, especially in intensive farming contexts. The chapter outlines the book’s methodology, examining the sustainability and justice implications of alternative food sources, including novel and lab-grown products. By imagining radical shifts in food systems, the chapter invites reflection on how global agriculture can be reimagined to prioritise equity, resilience, and sustainability.
