Stephan:   I think there is going to be a tremendous emphasis on this. It will become a growing trend, because industrial cattle operations are going to become unprofitable due to the rising cost of water as it becomes scarcer. It takes 1,300 gallons of water to produce an eight ounce hamburger. As affluence increases across the world -- not to be confused with wealth, only more than subsistence -- eating meat will increase. The demands for water and grain (and the water it requires) will become unsustainable.
