CEVAP:

States, in many subjects, would face some limitations of international regimes which constrain their sovereign rights, so they are blurred to determine the subjects either domestic or global in character. For example, use of waters, use of natural resources, protection of wild life, animal rights, prevention of environmental pollution are the subjects that states are not willing to share their authority, in time some developments such as globalization, economic, social and cultural interactions have caused these subjects to be international.
