Invasive Alien Species and the Law of the Sea: in search of a qualification

Alien invasive species are a growing concern, but are they an object as any other in international law ? An invasive alien species is a living species which, by its mere presence in an ecosystem outside its natural range, causes deleterious effects which is not the case in its native ecosystem. Is the law of the sea equipped to meet this new threat ? The classification of its effects in international law, and more specifically the law of the sea, is as innovative as capital. The legal treatment of invasive alien species so far has been tied to the struggle for the conservation of biological diversity without wondering, in advance, what its classification is. What if alien invasive species are considered pollution ? Considering this hypothesis means studying instruments of international law, and more precisely those of the law of the sea, as well as marine pollution. If one can allow to identify invasive alien species as a source of pollution, it remains a new form of pollution that has never been recognized before by the instruments of international law : a biological pollution. This pollution, independent of those already existing in international law, implies the need to rethink the definition of marine pollution.
