Water supply or lack of has always been one of the greatest threats on a global scale although one that is also often overlooked as many aren't able to comprehend something that seems so given as to its existence. Especially clean drinking water. Look at the Mayan collapse while much still remains a mystery but water appears to be at the heart of the collapse of an entire civilization.
Peace thinks clean drinking water will be gold, ruled and protected like oil fields sometime into the future. Water wars ?
