Environmental philosophy explores and occasionally justifies human interaction with the non-human world, analyzing the evolving relationship between humanity and nature. Green criminology, a relatively new and radical branch of criminology, investigates the causes and consequences of environmental harm—even when such harm is legally sanctioned—and aligns with the broader field of transgressive criminology. This paper aims to analyze a range of environmentally harmful behaviors that threaten the viability of life on Earth. Particular attention is paid to so-called “ordinary acts”—everyday practices carried out by individuals that, while socially acceptable and legally permissible, collectively exert a significant detrimental impact on the environment. These actions are typically normalized within daily routines and are seldom recognized as harmful. The study draws on established socio-psychological criminological theories—such as strain theory, social learning theory, and opportunity theory—to explore the underlying drivers of such behaviors and to interrogate their latent criminality within the context of environmental harm.
