Glad to see there are a few people who care about this stuff here. I think it is important to try to reduce animal suffering as well as human suffering, that's why I don't consume animal products/wear them and for that reason I would not procreate. As another posted out, the whole right to die movement, or whatever you'd like to call it, seems a bit linked to the idea of sparing suffering in general, which I feel is important. No living thing ought to be forced into a tortuous existence with no possibility of escape or relief. Also, I would argue that animals are, by their very nature, always innocent whereas humans rarely are, if ever. Humans have a sense of morality and a conscience, but they choose to stifle it, whereas animals may act in a way that seems immoral when viewed through a sort of lens of humanity, but they don't understand the ramifications of their actions when they act on instinct/impulse. A human has the capacity to discern right from wrong but they often ignore it.
