Great video sumisu, right on on all points, IMO. A crisis of some kind, natural or engineered could set off a bad chain reaction of the food supply. I have been watching the 4 Corners drought. Lake Powell is now lower than it was at the worst of the drought ending 5 years ago, 2014. It feeds Lake Mead and that could affect the water supply of Southern Cal, Vegas, parts of Az and more. A lot of rain moving into norther Cal this week, but maybe not much relief for the 4 Corners.
The Lake Powell link is not working today and it does not show 2014 anyway. Take my word, it is a couple of feet lower than its' bottom in 2014 and a couple mopre months to go to hit the normal bottom date. http://graphs.water-data.com/lakepowell/
