Initial claim: The idea of anthropocentrism that only humans can have moral consideration is problematic.
Objections: every living organism including humans are all made of cells. So if the structure is the same, all of them should worth equal moral consideration.
Possible Objections: It is true that people need all of the body parts in order to have a healthy life. But it doesn't mean that they are equally valued. Comparing with one little finger, our heart is more valuable.
Questions: How can we determine the species that have a different cell with us and animals. The objection is based on humans which means that the cells that humans have are valuable. But, plants might have different cells with us.
Improvement: The disruption part of the introduction could be more clear and straightforward.
