I agree that you are confused.
"But then go on to suggest that OECD countries are attempting to limit production unfairly?"
I never suggested that there was anything unfair about this. But that the advanced nations warehouse large amounts of food, and then dispose of it when it has gone bad, is well known and has been much discussed elsewhere.
"Food is perishable."
Annual production exceeds annual demand. Even when this year's food goes bad, next year there will be more, and it will be in excess of demand.
This is a big topic and I can not provide you with a full education on this topic. I'll recommend one book that I like, which is Diet For A Small Planet, by Frances Moore Lappe:
Seeing it from the production side I don't see that there is any attempt to suppress production. Everyone wants a good harvest and to produce as much product as they can. And, sometimes mother nature allows for it.
I feel there are honest attempts to feed people with that remaining food. And, there is the issue that sending food constantly to another country in need doesn't really address the problem. To paraphrase an old proverb, "Give a person a fish and they will eat for a day. Teach them to fish and they will eat for a lifetime." Ultimately, the food should be grown locally as much as possible to meet at least basic needs. Everything imported beyond that should be mere excess. That is how we will one day feed the world.
Thanks for the book btw.
