I am actually fairly new to Texas and spent most of my life in the Northeast. I talk about Texas because that is where I have to get MY food from at present. It also supplies a good deal of the cattle for the rest of the country. If grass-fed demand is so hard to keep up with in cattle country - it makes me wonder what will happen elsewhere.
Those floods up North (not normal like in Seattle) that corresponded to the radical drought here were extreme. Vermont had very strange weather which was the bookend to the drought. There are also other extreme weather patterns happening due to weather manipulation. East Texas is not desert was my point - not that it was tropical or ever would be. Desertification is not a global Texas attribute - but I am starting to wonder if it will become one. You can't make Dubai a lush green landscape (which is presently being attempted with weather manipulation) without causing issues in other places. You cannot have weather war-fare without all sorts of mishaps and unforeseen consequences.
I sometimes wonder if the supply of any kind of food - neolithic or paleolithic - might not suddenly be terminated in today's bizarre world. What I have learned about gmo and self-destructing seeds and how at present the vast majority of animals for food are fed gmo corn and soy has made realize that the general population is at risk. Here in my little part of the vast world the demand for grass-fed meats makes grass-fed bison $35 a pound when and if you can get it before it sells out. If the whole country suddenly no longer had it's regular meat or suddenly woke up and demanded only grass-fed and if you mixed in just a little weather hocus pocus - the prices could be astronomical.
I sure do hope it goes the other way and slowly but surely more and more small farmers turn to grass-fed because it makes better economical sense and then there is more supply and prices go down. I just somehow doubt it will happen that way. I think it will be more like butter. Take for instance the drought in England jacking up price of feed and therefore there is not enough butter:

I know I'm talking from my little experiences in my small neck of the woods - but all the examples I see around me point to prices going higher as demand goes up. For instance, marrow bones used be dirt cheap. People started asking for them so the price went from
$1 a pound to $5 a pound in one fell swoop at the store where I had bought them.
