Considered by many to be the father of the animal rights movement, Peter Singer is also considered by many to be opposed to fundamental human rights.

An Australian philosopher and bioethicist, today he is a Professor at Princeton University.
His appointment as a professor was marked with controversy and protest, mainly by disabled-persons' rights groups.

Amongst other things (including vegetarianism), Peter Singer advocates euthanasia, not just for the terminally ill, but also for newborns with serious disabilities (hemophilia, Down's syndrome, etc.).

His major writings include Animal Liberation, Democracy and Disobedience, Practical Ethics, Rethinking Life and Death, Ethics into Action, Should the Baby Live? and Animal Factories.
