High Quality Content by WIKIPEDIA articles! South Korea occupies the southern portion of the Korean peninsula. The total land mass of the country is 98,480km2 but usable land is only 20% of the total and thus the population is concentrated around the coast. The Korean Peninsula is surrounded by the East, West and South Seas, a coast-line that extends for about 2,413km. Endowed with an abundance of fisheries resources, Koreans have developed a distinct seafood culture with annual per capita sea food consumption of 48.1kg in 2005.
