Utilitarianism

 The Utilitarianism is a consequential ethic:  The rightness or wrongness of an action depends only upon the consequences of the action. This theory holds that utility or usefulness is the norm of morality because what is useful is always considered to be good. Although every good thing is useful to all sometimes every useful thing is not good to all. Ultimately, the victim of such kind is the environment. The theory of utility complements human chauvinism as the concept of usefulness depends on human interest. Consequently, other species in the biosphere are under risk. This theory also degrades environment as it receives just instrumental value. In utilitarianism, therefore, the only good thing is some form of happiness, or pain aversion, and actions are deemed ethical or unethical by how effectively they can maximize happiness and avoid pain.
