The war in Yemen centers on control of that entity's diminishing water supply. The government foolishly allowed for massive expansion of coffee crops, consuming much of that desert's water supply, and now the natives are restless due to local wells drying up. While political whores are wasting liters of this precious resource every second, Nestle, Coca Cola, et al are staking hoarding rights everywhere on the globe. Once, mankind was wiped out in a general flood, now mankind will be wiped out by thirst.
