The BBC reports on the rising cost of basic staples, such as wheat, soy, rice and corn. Surprisingly, corn is the least affected of those mentioned. For the last few months, corn used for biofuel has been blamed for the violence and protests over the cost of food. It was said that the land cleared for the biofuel production was leaving less room to grow food, and while this is true, it is the least liable of the trifecta affecting food prices.

The main culprits?

Increased population (It is estimated to reach 9 Billion by mid-century)

Increased Wealth in China and India (The trade and technology booms have hugely increased the number of wealthy- even middle class- citizens. This means they are adding meat, dairy and grains to their diets that may not have been before)

The third is a vast increase in the volume of food consumed globally. (From 1980-2007 the world went from eating 20kg of meat to 50kg on average.)
