Finishing unfinished food

I'm sure many of us had gone through this before; that whenever we can't finish our food, our parents or somebody else will just give a lecture of the starvation of those kids in someplace of poverty that they would struggle for food. The small loaf of bread that you just chucked away, if it were to thrown/tossed at Somalia, the kids would have to compete amongst themselves and fight for it. Then comes the teaching of how grateful we should be and this will goes on until you stuff your food into your mouth. Well, I had been finishing my food since and even at times I can't finish it, I'll stuff em down my throat.. Then 1 day I was thinking, after being so frigging overloaded with some buffet dinner...... Yes, it's true that we should be grateful that we have food to feed our mouth on the table.. but how does me stuffing the unfinished food into my stomach can actually help the kids? I mean, I with all my force, stuff those food into my throat, they starving. I leave...
