- Jungle
Jungle usually refers to a dense
forest in a hot climate, such as atropical rainforest . The word "Jungle" originates from theSanskrit word "Jangala" which means adesert or "uncultivated land" [http://www.answers.com/topic/jungle?cat=technology] . The term "Jungle" is prevalent in many colloquial languages of the Indian subcontinent and generally used to refer a densetropical forest or aswamp . About 6% of the Earth's land mass is classified as jungle. Jungles are vital to sustaining theecosystem s of the Earth as we know it. About 57% of all species live in jungle environments [http://www.bbc.co.uk/nature/programmes/tv/jungle/] . The term may still be used in a technical context to describe the forestbiome rainforest , a forest characterised by extensivebiodiversity and densely tangled undergrowth including youngtree s,vine s andliana s, andherbaceous plants. As a forest biome, "jungles" are present in bothequatorial andtropical climatic zones, and are associated with preclimax stages of therainforest . For this reason, jungle is to be distinguished from tropical rainforest in that the former is a profuse thicket of tropical shrubs, vines, and small trees growing in areas outside the light-blocking canopy of a tropical rainforest. Hence, 'jungle' is often found at the edges of climax rain-forests, where human activity may increase sunlight penetration.Not all regions called "jungles" would qualify as "rain forests" because many would apply "jungle" to the forests of northern
Thailand or southernGuangdong inChina : but scientifically, these are "monsoon forests" or "tropicaldeciduous forests" but not "rain forests".As a metaphor
Upton Sinclair gave the title "The Jungle " (1906) to his book about the life of workers at the Chicago Stockyards in order to imply that the workers were being mercilessly exploited and had no legal or other recourse.The term "
The Law of the Jungle " is also used in this kind of context, drawn from Rudyard Kipling's "The Jungle Book " (1894) - though in the society of jungle animals portrayed in that book and obviously meant as a metaphor for human society, that phrase referred to an intricate code of laws which Kipling describes in detail, and not at all to a lawless chaos.The "
Cities in Flight " science fiction series byJames Blish depicted spaceborne cities flying through the galaxy, which the writer compared to Hobos or Okies of space. The term "jungle", borrowed from the above Hobo term, is used for an area of space where such flying cities congregate.ee also
