Rabbits eat a lot of things that humans can't or won't and turn it into usable protein. The real problem is that the bunnies will likely end up butchered and served to North Korea's army, and the starving masses won't see a one.
I actually admire Pastor Cho, he has a well thought out program that would allow the people to help themselves out of starvation. He just doesn't seem to realize that NK is an evil regime with an evil leader who does not care how many people die to further his cause.
Also, imagine what the NK government would do to anyone who had the temerity actually to try to raise and sell rabbits to other North Koreans. The rabbits will be promptly butchered and fed to the army, resulting in ZERO famine relief. These nitwit ministers just can't bring themselves to realize that the NK famine is caused by communism, nothing else.
