Abstract
Environmental protection is considered as one of the basic values of society and one of the concerns of international law.

In this regard, legal and criminal protection of the environment is a priority of the measures taken. It is clear that by identifying the harmful factors to the environment and determining the guarantee of appropriate performances, the severity of the damage can be reduced to some extent and the future of the environment can be hoped for.

Finally, it seems that the expansion of cooperation and interaction between governments in the international arena, as well as the establishment of authoritative and fundamental rules with the necessary legitimacy, in the form of an independent and specialized basic structure in this field can be an effective action to achieve Complete goals in this area.
