Molecular genetics as evidence of environmental harm in ecocriminological analysis.

This research focuses on the potential of molecular genetics as a tool that can complement the assessment and evaluation of environmental damage from the perspective of green criminology or ecocriminology. This would have an impact on the effectiveness and efficiency of the mechanisms established for assessing the damage caused to ecosystems. We are facing a planetary crisis with the risk of ecosystem collapse, so it is proposed to overcome the limitations that we can identify in traditional criminal law by adopting an ecocentric approach reinforced with innovative mechanisms provided by science. This requires, among other things, recognising the intrinsic value of nature and committing to ecological justice. Molecular genetics methods, such as environmental DNA, metagenomics and population genetics, allow us to visualise the biological and ecological transformations induced by pollutants, even when these are invisible to the naked eye. These techniques provide objective and quantifiable data on biodiversity loss, changes in community composition and even possible genotoxic effects. Therefore, these molecular tests can complement preventive and restorative measures in environmental crimes. By fostering dialogue between science, law, and ethics, this study advocates for an integrated paradigm of environmental damage analysis in which molecular genetics enhances our ability to detect, understand, and legally address ecological damage. The convergence of green criminology, molecular genetics, and ecological justice reorients institutional responses toward restoring ecosystem integrity and defending the rights of nature.
