RAMOT HASHEVIM, ISRAEL - MARCH 14: Michael Aronheim feeds battery hens in their cages at his family's egg farm on March 14, 2008 in the farming community of Ramot Hashevim, central Israel. World food prices are soaring in the face of what some analysts are describing as a perfect storm of circumstances; increasing demand from developing economies in Asia, rising fuel prices, severe weather impacting recent harvests and an economic shift to biofuel production. All this leaves the consumer paying more for basic staples such as bread and milk and is likely to have its hardest impact on poorer nations. (Photo by David Silverman/Getty Images)
