The Removal of the Human Developmental Environment identifies a species‑level rupture that occurred within a single generation: the disappearance of the relational environment in which human development evolved. The paper argues that the core conditions required for stable identity, secure attachment, coherent cognition, and metabolizable meaning—locality, reciprocity, shared reality, embodied apprenticeship, predictable rhythms, constraint, and contribution—were structurally removed by modern technological, social, and informational systems.The result is a developmental mismatch unprecedented in human history. The paper shows how this mismatch produces predictable psychological and social consequences, including identity instability, attention dysregulation, emotional volatility, relational fragmentation, and the erosion of shared reality. These outcomes are not individual pathologies or cultural failures but the expected expression of an organism developing in an incompatible environment.The paper positions this removal as the central explanatory variable behind contemporary instability and outlines the structural requirements for reconstructing a functional developmental environment in modern contexts. It serves as the conceptual keystone for a broader field of research on environmental subtraction, developmental mismatch, and the reconstruction of human relational ecology.
