I was under the impression that hunger is primarily a distribution issue, not an issue of production. Gates implicitly states that the vitamin A deficit is mainly a result of a one-sided diet. But isn't the one-sided diet itself a result of a lack of alternatives? So, if alternatives cannot currently be distributed to meet demand, how would a new breed of bananas solve that? Don't they also have to get distributed in…
I think "distribution" in this context is just a nice way of saying that poor people can't afford better food from elsewhere, they have to rely on what is cheap and can be bought from the local market. If they're already buying bananas as a staple food, then I presume that the fix would be for the government to go to the local growers and either give the better banana plants for free, or at a discounted rate, or some…
Depends on location, I think. In the United States, yeah, that might be the case, but in other countries (I'm thinking parts of Africa), it is a distribution issue, particularly when dealing with corrupt governments.
