Worldwide rise of food prices

This video is a collection of film footage and photos about the worldwide rise in food prices.

Prices have risen dramatically in the last 3 years causing unrest in many lands as the people are hit even harder by the effects of inflation, poverty and greed.

The big companies who keep on raising their prices don't seem to be making any losses and are making larger profits than the previous year so is the rise of prices due to additional fuel costs as they claim ?

The background song is "Jail dem" by Trinidadian Calypsonian Roaring Lion.

I think his commentary despite being from 50 odd years ago is very appropiate to recent events.
