Jim Rogers is sounding the alarm -- buy agricultural commodities ahead of the riots. The financial crisis has cut off investment in agriculture, with many farmers unable to get loans for fertilizer according to Mr. Rogers. Of course, this means agricultural commodities will make a killing:

CNBC: "Sometimes in the next few years we're going to have very serious shortages of food everywhere in the world and prices are going to go through the roof."

Cotton and coffee are good buys because they are very distressed, while sugar, despite the fact that it has gone up a lot, is still down 70 percent from its all-time high, according to Rogers.

"I don't think that the problems of the world are behind us yet," he said.
