Salt is essential for the survival of human and animal life. Men have used salt as food preservatives, for cooking, and at funeral offerings. Salt is essential for all living creatures in small quantities. Salt regulates the water content of the body, and is used for electrical signaling in the nervous system. Because of its importance to survival, salt has often been considered a valuable commodity during human history. However, as salt consumption has increased, many modern nations have consumed too much salt leading to health risks, such as high blood pressures. There is, however, an exception to this. North Korea is suffering from salt shortages. Due to typhoon damages, North Korea's salt production has dropped, leaving many North Koreans, including even the soldiers, in dire need of salt. A year ago, I heard that North Korean soldiers ate salt as snack because they had nothing other to eat. Now, they don't even have salt to eat. When soldiers were unable to get access to salt in military, they are leaving their posts and returning to their home to find salt. North Korea is suffering not only from food shortages, but also from salt shortages. I wonder how they will fight if a war breaks out.
