According to New Focus, a press specialized in North Korea, North Korean people are collecting cigarette filters to use as bed sheet fills. These filters act as substitutes for cotton. There have been reports of North Korean people fighting over cigarette filters thrown on the street. Moreover, when North Korean soldiers tried to raise goats to solve the malnutrition problem, the goats died because the goats had nothing to eat. If you take a look at North Korea through Google Map, you will notice that mountains in North Korea are barren. I don't understand why North Korea is so barren and why the people tolerate the evil dictator rule.
