Destruction of the environment was a “military tactic” that began as early as the twelfth century BC in the Assyrians, who used “destruction of the life-support system, not as part of siege tactics but as recompense for a rebellious enemy – one that was either defeated or that could not be defeated” (emphasis added).
“I shut him up in his city, carried off the grain of his fields, cut down his orchards”, says the Assyrian King Shalmaneser III (858-824 BC) in his eighth year in battles against the rebels in Babylonia.
