"BACKGROUND:War and armed conflict has many damaging effects on the natural environment. For example, crops are destroyed, water supplies are poisoned and forests are burnt. New technology that is used for war means that the destruction and damage of the environment is more serious and the long-term consequences can be worse.
On November 5, 2001, the UN General Assembly declared November 6 of each year as the International Day for Preventing the Exploitation of the Environment in War and Armed Conflict (resolution 56/4). The assembly considered that that any environmental damage in times of armed conflict impairs ecosystems and natural resources long after the period of conflict. This damage can often extend beyond the limits of national territories and today’s generation. The assembly also recalled the United Nations Millennium Declaration, which emphasized the necessity of working to protect the environment."
