I am thoroughly confused by the ethics of vegetarianism, which to my mind seems more of a religious objection towards eating meat than a scientific point of view.
Recently I attended a lecture by Peter Singer (<i>Animal Liberation</i>) on the ethics of eating meat. One thing he did not address was differentiating between the 'killing' of the (sentient) animal and the 'eating' of it.
OK- so here is my question: is it ethical to eat roadkill, or animals that have died of "natural" causes or of "old age"? Further to this, is being killed by a human primate not a "natural" cause of death of a cow?
If humans shouldn't kill cows to eat (because we know better), perhaps we could let lions kill the cows, then we can eat them afterwards?
Isn't it unethical to tell people in the developing world they shouldn't eat meat? - especially when a huge percentage of women in the developing world are iron deficient?
