Dont forget pistachios. The Wonderful Company grows tons of pistachios in California that can take up to 40-50 gallons per day per tree. Remember folks, your water is going to a luxury snack food!
The world would revolt if beef disappeared.
Or perhaps US would just have to revise the beef quotas it sets on foreign exporters. A lot of California farm production is designed with costs borne by the public and profits kept private.
It wouldn't stay competitive without a mount of legislative work, quotas and tariffs.
