Another Famine?

According to an article from the BBC, there is a possibility of famine conditions resuming in North Korea. The article mentions the grams of food average urban North Koreans eat compared to what is recommended. It's really shocking, especially considering most Americans probably eat well over the recommedations. North Korea's talk of possibly returning to 6-party talks may be because they hope food aid they previously got from the US, Japan, and South Korea will resume.
