CA's central valley is productive enough to supply the entire U.S. with enough food to eat, and they have water coming out their ears (if they had not torn out all their dams and flush most of it down the rivers in order to save a certain small fish.)
Climate change will destroy the agricultural sector in the Central Valley. Already, the state is facing a severe drought, and the situation is likely to escalate in the future. Also, the water-rich Northern California is heavily Republican, and they are unlikely to support the secession.
Pesticides and/or geoengineering and/or something already has done great damage. My bee-keeper friend tells me with some authority that keepers don't even bring their bees there anymore, and isolate their non-CA hives from any which have been in the central valley because something which nobody understands is going on. But not to worry: robotic drone bees can come to the rescue so I read in the new-age scientism rags. I'm sure they won't be doing double-duty by data collecting (aka, spying) with a high granularity though.
As for water, I note with interest that under the super-eco government they were poisoning aquifers with oil drilling waste. Wouldn't it be a crying shame if the state developed a severe shortage of water? I mean in such a disaster poor Jerry and his minions might need to take a lot more control of even more aspects of resource management and people would have to pay a lot more for water. People might just have to be stack-n-pack'd in mega-regions. To 'save the earth' ya-know.
One very key element of 'austerity' is that those who control resources (multi-national corporate interests mostly these days) can get a lot more money for a lot less product. 'Climate change' is a total scam, but it is only part of the game here. An important and key part to be sure however.
Bees are dying all over the world. It's probably not genetic engineering is to blame. I think the reason is that fields are treated with herbicides and pesticides. Bees are not adapted to them.
