I don't need to convince anyone. The historic documentary evidence is pretty clear.
Btw, ya never did say, if they shut off the imported water in the OC/LA basin, how long do ya think the water there would last 25,000,000 water consuming people?
I'd give it about 2 hours.☺
I don’t know, but it wouldn’t take long for those areas that rely on irrigation (not the foothills and other natural areas) to return to the natural state of vegetation, which by the way, is not identical to the desert. I posted a LONG time ago that the area is overbuilt in terms of sustainability through local water resources. Most major cities are, and even if there’s enough water, there’s not enough food grown locally, or some other resource needed for modern urban life. Hell, ancient Rome couldn’t have supported its population two thousand years ago without aqueducts bringing water from other areas.
My only issue is the contention that the Southern California coastal plain is situated in a desert. It’s demonstrably not, under any definition except yours.
