Steve,
Water is required to grow food. I don't know what the situation is down in Southern Calif., but up here farmers are just not going to have water to grow much and the dairy business is going down fast. All are gone from up here and many others are selling their dairy cows for beef or to people in other states. Even people around here with small gardens are being told they will be limited to the amount of water they can use without paying a huge penalty.
