Psychosocial deprivation of animals

Impoverished animal environments
Behavioural monotony of captive and domesticated animals
Animal boredom
Animals kept under unchanging conditions which offer them little incentive to move and explore their environment may easily become bored, especially when the environment does not permit them to participate in their normal cycles of relationship with those of the same or different species. They then exhibit abnormal behaviour patterns, such as the repetitive pacing and rubbing frequently observable in zoos.
Imposing unstimulating conditions on animals is tantamount to destroying their spirit and effectively denies recognition of their role in the planetary ecology.
Man is the only animal that can be bored. Animals are quite content when they are regularly fed and do not have to compete in the wild for scarce food.
