competition
Competition in biology and sociology, is a contest between two or more organisms, animals, individuals, groups, etc., for territory, a niche, for a location of resources, for resources and goods, for mates, for prestige, for recognition, for awards, for group or social status, or for leadership. Competition is the opposite of cooperation.〔(Competition ), Sociology guide〕 It arises whenever at least two parties strive for a goal which cannot be shared or which is desired individually but not in sharing and cooperation. Competition occurs naturally between living organisms which co-exist in the same environment.〔Keddy, P.A. 2001.
''Competition'', 2nd ed., Kluwer, Dordrecht. 552 p.〕 For example, animals compete over water supplies, food, mates, and other biological resources. Humans usually compete for food and mates, though when these needs are met deep rivalries often arise over the pursuit of wealth, prestige, and fame. Competition is also a major tenet of market economies and business is often associated with competition as most companies are in competition with at least one other firm over the same group of customers, and also competition inside a company is usually stimulated for meeting and reaching higher quality of services or products that the company produce or develop.

Competition can have both beneficial and detrimental effects. Many evolutionary biologists view inter-species and intra-species competition as the driving force of adaptation, and ultimately of evolution. However, some biologists disagree, citing competition as a driving force only on a small scale, and citing the larger scale drivers of evolution to be abiotic factors (termed 'Room to Roam'). Richard Dawkins, prefers to think of evolution in terms of competition between single genes, which have the welfare of the organism 'in mind' only insofar as that welfare furthers their own selfish drives for replication (termed the 'selfish gene').
Some social darwinists claim that competition also serves as a mechanism for determining the best-suited group; politically, economically and ecologically. Positively, competition may serve as a form of recreation or a challenge provided that it is non-hostile. On the negative side, competition can cause injury and loss to the organisms involved, and drain valuable resources and energy. In the human species competition can be expensive on many levels, not only in lives lost to war, physical injuries, and damaged psychological well beings, but also in the health effects from everyday civilian life caused by work stress, long work hours, abusive working relationships, and poor working conditions, that detract from the enjoyment of life, even as such competition results in financial gain for the owners.
