I have a feeling, that in general worlds hunger problem is unsolvable. There are regions in the world, that suffer hunger due to their location. And the only way to solve this issue is to either move whole population somewhere, or make such donations temporary and infinite. This would be as same as donation 6 billion to solve covid problem and make vaccine. But covid problem is not about people getting vaccinated. Vaccinated people still get infected and die. Same I see is with hunger, hungry people can be feed, but in a week, month or a year 6 billions will be spent and they will become hungry again. 6 billions is a help, but not a solution.
Real areas with critical living conditions - probably about 1-2%, no more. The problem for everyone else - from laziness to habits / traditions / religious characteristics, etc. That is - depending exclusively on the "suffering" themselves. Moreover, the practice of constant "maintenance", for people who were really suffering yesterday, develops today the habit of what someone will think for them, will feed and support them. Until international funds start building industrial facilities for their money and training staff in locations with hunger, instead of simply eating them up, the situation will not only not change, moreover, it will noticeably worsen! The consumers of our help are completely degrading the concept of responsibility, they know that in any case they will be fed, they continue to do nothing, have a huge number of children, and continue to demand that all of them be fed ... And very soon they will become a new weapon of mass destruction " humanitarian terrorism ", some of them are already being used for these purposes
