It seems to me that the situation is very fragile and worrisome, mainly for 2 reasons. China once (1958-1962) had a Four Pests Campaign (除四害运动), which defined four pests to be eliminated: rats, flies, mosquitoes, and sparrows. In less than 1 year, nearly 2 billion sparrows were systematically exterminated. I'm not saying that North Korea will do the same thing, but a starving country with a totalitarianism government is one of the worst threats to nature, as China has clearly shown. On the other hand, should the political situation change in North Korea (in any direction), nature will as well be the first to suffer, as China has clearly shown.
