The Korean War that broke out on June 25, 1950 came to a ceasefire on July 27, 1953, leaving numberless scars. The truce space of DMZ (Demilitarized Zone) between South Korea and North Korea has become a valuable treasury of ecosystem in the world for almost 70 years. The special exhibition of the National Institute of Ecology illustrates the ecology of the DMZ area as a land of lives. It is an opportunity to be reminded of the significance of peace realized by the natural ecosystem, overcoming the hurts of the war.
