I mean, just look at that first picture. It's a small child sitting in a sandy place with a stainless steel bowl with porridge like food inside. There is no civilization in sight. Maybe some village houses, which represent the bare minimum shelter needed. So now you get to ask yourself, should I feel pity or should I recognize that this child is not living in an environment that is conductive to escaping poverty? If I do take pity, will people pity me if I do a hike without food and end up starving on some forest path far away from civilization? I somehow doubt they would pity me.
My point is, this problem is fundamentally unsolvable without either bringing civilization to these people or bringing the people to civilization. Taking pity on them doesn't do anything except maybe convince yourself that you did your part.
Fighting against world hunger feels like a worthy goal that is fulfillable but it isn't. You don't solve world hunger by feeding people, you solve it by restructuring society.
