Back To Square One?

The Economist discusses the food crisis:

Roughly a billion people live on $1 a day. If, on a conservative estimate, the cost of their food rises 20% (and in some places, it has risen a lot more), 100m people could be forced back to this level, the common measure of absolute poverty. In some countries, that would undo all the gains in poverty reduction they have made during the past decade of growth. Because food markets are in turmoil, civil strife is growing; and because trade and openness itself could be undermined, the food crisis of 2008 may become a challenge to globalisation.
