A "food shortage" crisis is on the way, but it is a "manufactured" or contrived crisis.
For the past several decades, a number of large multi-national corporations have been buying out smaller independant companies throughout the food storage/processing/distribution/retail system. Once they reach a high enough level of "ownership", they will do to food what has been done to oil production. Once they control the "market", they will start raising prices and generating shortages to justify raising them even higher.
We've already seen parts of it happening. Just look at all the "hype" lately about coming food shortages because some grain is being used to produce fuel. There is no world-wide shortage, but the ... perception ... of one has been created, and prices for grain are climbing rapidly.
We have plenty of food. The only "crisis" is in distribution of that food, and "who" makes the most money off of it.
Right now, there are 5 multi-national companies that control over 95% of all the grain bought/sold throughout the world. 5 companies! All that grain goes through their hands at some point. When they decide to make more money, they will start manipulating the markets to drive up the prices - just as those "energy" companies have done. They set the example, and now others are going to follow their "business processes".
No, those big corporations are not buying up farm land. That's the one part of the whole Food system that has the highest expenses and least amount of profit (if any). The real money is made by everything in between the farmer/producer and the consumer - from trucking to processing to storage to retail.
Use of the organ meat of animals has always been done. And it makes good economical sense. Those celebrity chefs are just doing it for the "shock" appeal and tv ratings. It's the new unique "fad" thing to do.
Just my humble thoughts to share. Take them as such.
