Piyavadana

Playing with the lives of other beings without sensitivity or hesitation as in the act of hunting or fishing for sport is an act of heedless, needless violence: A violation of the solemn rights
of all living beings
 
Being attentive to the nature of interdependence of all creatures both animate and inanimate, one should never slacken in one’s efforts to preserve and conserve nature’s energy.

His Holiness the Dalai Lama
