So one would expect $14b/year would solve about 14/93 = 15% of world hunger.
> The World Food Programme supports over 152 million people annually and delivers life-saving food assistance where needed most. (https://en.wikipedia.org/wiki/World_Food_Programme)
An estimated 757 million people are food insecure (https://www.who.int/news/item/24-07-2024-hunger-numbers-stub...)
152/757 = the world food program helps ~20% of people who are food insecure. That's well in the ballpark of the estimated 15% spend.
If we spend that extra $93b, we'd be well within the range to actually stop world hunger.
Yes, "climate change, draught, poverty, colonialism, racism, illiteracy, lack of education" are still issues. No, you don't have to solve those problems to feed people. Don't let perfect be the enemy of good.
