Practice Relating to Rule 43. Application of General Principles on the Conduct of Hostilities to the Natural Environment
In 1992, during a debate in the Sixth Committee of the UN General Assembly on protection of the environment in times of armed conflict, Argentina recommended that:
Belligerents engaged in an armed conflict, whether international or non-international, should always bear in mind that the protection of the environment affects the well-being of humanity as a whole. They should therefore use those means which are least apt to cause damage to the environment, damage for which they would be responsible.
