The Demilitarized Zone (DMZ) Is the unmanned strip of land that exists between North Korea and South Korea. The DMZ has been a representation of the two nation's tension for over 50 years and it is a contributing factor of the events that led to The Korean War in 1950. During the Armistice between the two nations the ecosystem of the area has reverted to its natural state due to the lack of human interference; The DMZ and Civilian Control Zone (CCZ) in South Korea encompass many rivers and an abundant amount of diverse ecosystems along with substantial amounts of plant, mammal, fish and bird species, many of which are globally endangered.
