I agree that the subdivisions may not be turned into arable land or, if it happens, it is a very long-term proposition. But some subdivisions are being razed already. The houses are in such a decrepit condition, they have to be razed.
I remember over ten years ago, I was doing a job in San Pedro. The job took me to the docks in San Pedro and Terminal Island--even back then the canneries were being moved out to places overseas. Now there are none left.--where I watched the local fisherman unload their boats with their catch of the day. I thought I might buy some fish, but I learned that it wasn't being sold in the U.S. It was all being frozen and shipped to Japan. THEN, it was being processed, packaged and shipped back to the U.S.!!!! I think the point of the article is that this may not be a very economical way to do things anymore. Will the canneries come back to San Pedro and Terminal Island. I don't know. But I think the old way of doing things no longer makes financial sense.
