What the problem isIn a nutshell: people are starving. They can't feed themselves, for two basic reasons: incentives for others to prevent them, and lack of infrastructure. The incentives are easier to address, so I'll talk about that first.
To us, starvation is a tragedy. To others, it's a business opportunity. There is a strong strand of thought that views poverty and inequity as good things; they provide the motivation for improvement, and a motor for economic growth. This is a naïve view at best, so I'm not going to waste time refuting it here.
( As far as infrastructure goes – well, let's think about what's needed to eat well )
