Section A. Widespread, long-term and severe damage
In its written statement submitted to the ICJ in the Nuclear Weapons case in 1995, Ecuador stated:
The effects of the use of nuclear weapons will, in all cases, have devastating effects on the environment. Consequently, it is contrary to the humanitarian conditions that prohibit the destruction of the environment, which is the only guarantee of the survival of the human species, and of the whole chain of life of the planet.
