I suspect that it doesn't get talked about because no one has a sound byte solution to it, and the problem doesn't provide a political advantage for anyone.
Realistically, many people in the western world don't care because they won't feel the hunger pains themself and the consequences of having hundreds of millions of starving people are not obviously appearant. People don't necessarily consider the health (starving people are far more likely to carry diseases which can mutate and threaten everyone) and geopolitical consequences (starving people will follow ANYONE who promises food) from having a large population of starving people.
