You meant it as a joke but by far and large hunger is a problem of the past. Massive famines have not occurred in years, and where they do it's because of political disorders like conflicts or civil wars.
The capacity for ending hunger is here.
Probably UK companies throw out enough food to feed all those who're hungry in their locality [1]. But hunger is still a big problem. It's going to get worse here too. The recession brought food prices up significantly, Brexit will do so to.
[1] high-street companies used to sell off perishable goods cheaply at the end of the day. Now they lock them in bins. Because poor people would buy them to save money, poorer people would "steal" then from the bins.
There's also increasing problems inside first world countries: https://policy-practice.oxfam.org.uk/blog/2014/06/uk-hunger-...
It's also possible that hunger is a leading indicator of conflicts. I've heard this cited as a cause of the Arab Spring, and water conflict is a factor in the war in Yemen.
B) There's currently at least one massive famine going on RIGHT NOW in Yemen that gets pretty much no attention. Yes, it' due to a conflict, but that doesn't mean it isn't happening.
