The recent news of a "global bacon shortage" has stirred some pork lovers into a bit of a panic. As CBS news reports,

"Britain's National Pig Association, "the voice of the British pig industry," warned recently that a global shortage of bacon and pork "is now unavoidable" because of shrinking herds. The trade group reported Thursday that annual pig production for Europe's main pig producers fell across the board between 2011 and 2012, a trend that "is being mirrored around the world." The group tied the decline to increased feed costs, an effect of poor harvests for corn and soybeans."

This is simple economics. If the price of an input (feed) of a good is rising, it should be expected that production of that good will decrease and the price of that good will increase. This may lead to a temporary shortage, but that's not reason to panic as the market always has a way of correcting itself: As the price of feed rises, the amount of feed purchased by pig farmers will decrease which means the amount of pigs they will be able to produce will decrease. this will create a temporary shortage as demand of pork outweighs production. over time the market will correct for this by raising the price of pork which will increase pig farmers profits making them more willing and able to buy more feed so they can produce more pork until an equilibrium price is reached where amount of pork pig farmers are willing/able to produce and sell at price X = amount of pork consumers are willing/able to consume at price X.
