The U.N. World Food Program (WFP), the largest anti-hunger initiative around the globe, is grappling with the worst funding shortage in its 60-year history and "we are in a desperate situation," Executive Director Cindy McCain said on Sunday.

"It's a combination of things -- it's COVID, it's climate change, it's conflict and also the cost of being able to do business," McCain told ABC "This Week" co-anchor Jonathan Karl about the reasons behind the lack of money. "Those things combined and, of course, a world that has kind of grown tired of all this. There's a great malaise right now within countries about foreign aid and giving."

"The bottom line is those that are going to suffer [are] those who can't afford to," McCain said.

In September, the WFP said it "has been struggling to meet the global need for food assistance .... And for the first time ever, WFP has seen contributions decreasing while needs steadily increase." The organization has already had to make "significant cuts in hot spots such as Afghanistan, Bangladesh, Democratic Republic of Congo, Haiti, Jordan, Palestine, South Sudan, Somalia, and Syria."
