Steve F. Sapontzis: Doing

“1. We are morally obligated to alleviate unjustified animal suffering that it is in our power to prevent without occasioning as much or more unjustified suffering.
2. Innocent animals suffer when they are preyed upon by other animals.
3. Therefore, we are morally obligated to prevent predation whenever we can do so without occasioning as much or more unjustified suffering than the predation would create, and we are also morally obligated to attempt to expand the number of such cases.”

Animals , Suffering

“When healthy animals, whose prospects include the possibility of lives that are worth living, are killed, then they suffer the loss of those prospects, even if they do not suffer pain or anxiety in the killing process. So, the mass killing or "slaughter" of animals for food always involves mass suffering. If the phrase "humane slaughter" is supposed to indicate a killing process without suffering, it is a false label.”

“Where we can prevent predation without occasioning as much or more suffering than we would prevent, we are obligated to do so by the principle that we are obligated to alleviate avoidable animal suffering. Where we cannot prevent or cannot do so without occasioning as much or more suffering than we would prevent, that principle does not obligate us to attempt to prevent predation.”

“When our interests or the interests of those we care for will be hurt, we do not recognize a moral obligation to "let nature take its course," but when we do not want to be bothered with an obligation, "that's just the way the world works" provides a handy excuse.”
