"The company announced in January 2016 that it paid $31.8 million for 1,790 acres. Some of its fields run alongside the Colorado River.
The company grows hay for cows in its dairy in Saudi Arabia, where the monarchy has set a policy of growing less alfalfa, wheat and corn to reduce pumping of groundwater from the depleted aquifers of the Arabian Peninsula."
While I agree the pitfalls of unchecked Capitalism are rather dire, you have to realize this business model is only possible because of USDA subsidies; under no other circumstances could this be a profitable endeavor if ti were left to Market forces alone, were it not for the State offsetting the obscene expenses it simply wouldn't be possible.
Furthermore, insuring these crops should be a matter for those respective nations and a premium should be placed on them as that is their final destination--especially since the House of Saud refuses to use it's own water but expects CA to use it's fertile soil and limited water supply to feed its dairy cattle.
