The collapse of the water system will happen one day. The delicate ecosystem that is California will reclaim itself. It's just about a matter of time. Weather trends from the past drove native peoples to change how and where they lived. Look at how "modern man" has changed the landscape/waterways to suits our needs. The fires grow more intense every year. IT will happen. When? Some scoff at "Global Warming" because they fail to see "The bigger picture". There are so many variables to consider in what actually drives the weather. It is in fact, global. WE are having a profound impact, PERIOD. For anyone to deny that is pure folly and a serious lack of knowledge on how things really work.
