Given the scope of environmental criminal type there is a needy of addressing it under the light of the principles of minimum in- tervention of criminal law and insignificance, to use the criminal sanction in extreme cases, given the ineffectiveness of civil and administrative penalties. The application of these principles is not totally accepted by the majority jurisprudential scholars and un- derstandings that underlie their inconsistency with the principles of prevention and precaution, grounds of environmental law, una- ble to verify the actual enhancement of environmental damage to the ecosystem, beyond all the environmental damage generate extremely gravity. Given this impasse, this study aims at demons- trating the principle of insignificance in the environmental crimes, showing the divergence of doctrine and jurisprudence.
