The UN food chief warned Tuesday the war in Ukraine has created “a catastrophe on top of a catastrophe” and will have a global impact “beyond anything we've seen since World War II" because many of the Ukrainian farmers who produce a significant amount of the world's wheat are now fighting Russians. David Beasley, executive director of the UN World Food Program, told the UN Security Council that already high food prices are skyrocketing. His agency was feeding 125 million people around the world before Russia's invasion of Ukraine on Feb 24, and Beasley said it has had to start cutting their rations because of rising food, fuel and shipping costs. He pointed to war-torn Yemen where 8 million people just had their food allotment cut 50%, “and now we're looking at going to zero rations.”
