Colocasia is a genus of 25 or more species of flowering plants in the family Araceae, native to tropical Polynesia and southeastern Asia. Common names include Elephant-ear, Taro, Cocoyam, Dasheen, Chembu, and Eddoe. Elephant-ear and Cocoyam are also used for some other large-leaved genera in the Araceae, notably Xanthosoma and Caladium. The generic name is derived from the Greek word for Nelumbo nucifera, κολοκασιον (kolokasion). It is thought to be the oldest cultivated plant in the world, having been cultivated in Asia for more than ten thousand years.

They are herbaceous perennial plants with a large corm on or just below the ground surface. The leaves are large to very large, 20–150 cm (7.9–59 in) long, with a sagittate shape. The elephant's-ear plant gets its name from the leaves, which are shaped like a large ear or shield. The plant reproduces mostly by means of rhziomes (tubers, corms) but it also produces "clusters of two to five fragrant inflorescenes in the leaf axils". Like other members of the family, the plant contains an irritant which causes intense discomfort to the lips, mouth and throat. This acridity is caused in part by microscopic needle like raphides of calcium oxalate monohydrate and in part by another chemical, probably a protease. The acridity helps to naturally deter herbivores from eating it. It must be processed by cooking, soaking or fermenting - sometimes along with an acid (lime or tamarind) before being eaten. The species is dangerously invasive into wetlands along the American Gulf coast, where it threatens to displace native wetland plants. As only a few examples, it is on the invasive species list for Texas and Florida

The Korean War (Korean: 한국전쟁 or 조선전쟁, Hanja: 韓國戰爭 or 朝鮮戰爭; 25 June 1950 – 27 July 1953) was a war between the Republic of Korea (supported primarily by the United States of America, with contributions from allied nations under the aegis of the United Nations) and the Democratic People's Republic of Korea (supported by the People's Republic of China, with military and material aid from the Union of Soviet Socialist Republics). The Korean War was primarily the result of the political division of Korea by an agreement of the victorious Allies at the conclusion of the Pacific War at the end of World War II. The Korean Peninsula was ruled by the Empire of Japan from 1910 until the end of World War II. Following the surrender of the Empire of Japan in September 1945, American administrators divided the peninsula along the 38th parallel, with U.S. military forces occupying the southern half and Soviet military forces occupying the northern half.
