THAT product shortage is likely due to the water shortages in CA, and high demand worldwide for almond products. Some searching will show that the subject has been beat to death on FR. But, suffice it to say, given the average climate in CA over the last several thousands of years, and the present population, almonds are an unsustainable product, there. As are several others. Even some of the fisheries are probably only sporadically practical.
Thanks for the info.
