Peter Singer has popularized the term "speiciesism." It's the idea that we are biased or prejudiced towards our own species. Therefore, the argument says, we should have equal consideration for animals. However, this won't apply to animals. The lion will still eat the gazelle, the sharks will eat the dolphins, and any carnivore will eat any animal. I can imagine Singer replying that animals don't have the rational capacity to do ethics. The ideas that Singer presents only applies to us humans. But if this is the case, isn't that a form of speciesism?
